# Alt-Svc
curl features support for the Alt-Svc: HTTP header.
## Enable Alt-Svc in build
`./configure --enable-alt-svc`
(enabled by default since 7.73.0)
## Standard
[RFC 7838](https://datatracker.ietf.org/doc/html/rfc7838)
# Alt-Svc cache file format
This is a text based file with one line per entry and each line consists of nine
space separated fields.
## Example
h2 quic.tech 8443 h3-22 quic.tech 8443 "20190808 06:18:37" 0 0
## Fields
1. The ALPN id for the source origin
2. The hostname for the source origin
3. The port number for the source origin
4. The ALPN id for the destination host
5. The hostname for the destination host
6. The port number for the destination host
7. The expiration date and time of this entry within double quotes. The date format is "YYYYMMDD HH:MM:SS" and the time zone is GMT.
8. Boolean (1 or 0) if "persist" was set for this entry
9. Integer priority value (not currently used)
If the hostname is an IPv6 numerical address, it is stored with brackets such
as `[::1]`.

libcurl bindings
================
Creative people have written bindings or interfaces for various environments
and programming languages. Using one of these allows you to take advantage of
curl powers from within your favourite language or system.
This is a list of all known interfaces as of this writing.
The bindings listed below are not part of the curl/libcurl distribution
archives, but must be downloaded and installed separately.

# The curl bug bounty
The curl project runs a bug bounty program in association with
[HackerOne](https://www.hackerone.com) and the [Internet Bug
Bounty](https://internetbugbounty.org).
## How does it work?
Start out by posting your suspected security vulnerability directly to [curl's
HackerOne program](https://hackerone.com/curl).
After you have reported a security issue, it has been deemed credible, and a
patch and advisory has been made public, you may be eligible for a bounty from
this program. See the [Security Process](https://curl.se/dev/secprocess.html)
document for how we work with security issues.
## What are the reward amounts?
The curl project offers monetary compensation for reported and published
security vulnerabilities. The amount of money that is rewarded depends on how
serious the flaw is determined to be.
Since 2021, the Bug Bounty is managed in association with the Internet Bug
Bounty and they set the reward amounts. If it would turn out that they set
amounts that are way lower than we can accept, the curl project intends to
"top up" rewards.
In 2025, typical "Medium" rated vulnerabilities are rewarded 2,500 USD each.
## Who is eligible for a reward?
Everyone and anyone who reports a security problem in a released curl version
that has not already been reported can ask for a bounty.
Dedicated - paid for - security audits that are performed in collaboration
with curl developers are not eligible for bounties.
Vulnerabilities in features that are off by default and documented as
experimental are not eligible for a reward.
The vulnerability has to be fixed and publicly announced (by the curl project)
before a bug bounty is considered.
Once the vulnerability has been published by curl, the researcher can request
their bounty from the [Internet Bug Bounty](https://hackerone.com/ibb).
Bounties need to be requested within twelve months from the publication of the
vulnerability.
The curl security team reserves themselves the right to deny or allow bug
bounty payouts on its own discretion. There is no appeals process.
## Product vulnerabilities only
This bug bounty only concerns the curl and libcurl products and thus their
respective source codes - when running on existing hardware. It does not
include curl documentation, curl websites, or other curl related
infrastructure.
The curl security team is the sole arbiter if a reported flaw is subject to a
bounty or not.
## Third parties
The curl bug bounty does not cover flaws in third party dependencies
(libraries) used by curl or libcurl. If the bug triggers because of curl
behaving wrongly or abusing a third party dependency, the problem is rather in
curl and not in the dependency and then the bounty might cover the problem.
## How are vulnerabilities graded?
The grading of each reported vulnerability that makes a reward claim is
performed by the curl security team. The grading is based on the CVSS (Common
Vulnerability Scoring System) 3.0.
## How are reward amounts determined?
The curl security team gives the vulnerability a score or severity level, as
mentioned above. The actual monetary reward amount is decided and paid by the
Internet Bug Bounty..
## Regarding taxes, etc. on the bounties
In the event that the individual receiving a bug bounty needs to pay taxes on
the reward money, the responsibility lies with the receiver. The curl project
or its security team never actually receive any of this money, hold the money,
or pay out the money.

# BUGS
## There are still bugs
curl and libcurl keep being developed. Adding features and changing code
means that bugs sneak in, no matter how hard we try to keep them out.
Of course there are lots of bugs left. Not to mention misfeatures.
To help us make curl the stable and solid product we want it to be, we need
bug reports and bug fixes.
## Where to report
If you cannot fix a bug yourself and submit a fix for it, try to report an as
detailed report as possible to a curl mailing list to allow one of us to have
a go at a solution. You can optionally also submit your problem in [curl's
bug tracking system](https://github.com/curl/curl/issues).
Please read the rest of this document below first before doing that.
If you feel you need to ask around first, find a suitable [mailing
list](https://curl.se/mail/) and post your questions there.
## Security bugs
If you find a bug or problem in curl or libcurl that you think has a security
impact, for example a bug that can put users in danger or make them
vulnerable if the bug becomes public knowledge, then please report that bug
using our security development process.
Security related bugs or bugs that are suspected to have a security impact,
should be reported on the [curl security tracker at
HackerOne](https://hackerone.com/curl).
This ensures that the report reaches the curl security team so that they
first can deal with the report away from the public to minimize the harm and
impact it has on existing users out there who might be using the vulnerable
versions.
The curl project's process for handling security related issues is
[documented separately](https://curl.se/dev/secprocess.html).
## What to report
When reporting a bug, you should include all information to help us
understand what is wrong, what you expected to happen and how to repeat the
bad behavior. You therefore need to tell us:
- your operating system's name and version number
- what version of curl you are using (`curl -V` is fine)
- versions of the used libraries that libcurl is built to use
- what URL you were working with (if possible), at least which protocol
and anything and everything else you think matters. Tell us what you expected
to happen, tell us what did happen, tell us how you could make it work
another way. Dig around, try out, test. Then include all the tiny bits and
pieces in your report. You benefit from this yourself, as it enables us to
help you quicker and more accurately.
Since curl deals with networks, it often helps us if you include a protocol
debug dump with your bug report. The output you get by using the `-v` or
`--trace` options.
If curl crashed, causing a core dump (in Unix), there is hardly any use to
send that huge file to anyone of us. Unless we have the same system setup as
you, we cannot do much with it. Instead, we ask you to get a stack trace and
send that (much smaller) output to us instead.
The address and how to subscribe to the mailing lists are detailed in the
`MANUAL.md` file.
## libcurl problems
When you have written your own application with libcurl to perform transfers,
it is even more important to be specific and detailed when reporting bugs.
Tell us the libcurl version and your operating system. Tell us the name and
version of all relevant sub-components like for example the SSL library
you are using and what name resolving your libcurl uses. If you use SFTP or
SCP, the libssh2 version is relevant etc.
Showing us a real source code example repeating your problem is the best way
to get our attention and it greatly increases our chances to understand your
problem and to work on a fix (if we agree it truly is a problem).
Lots of problems that appear to be libcurl problems are actually just abuses
of the libcurl API or other malfunctions in your applications. It is advised
that you run your problematic program using a memory debug tool like valgrind
or similar before you post memory-related or "crashing" problems to us.
## Who fixes the problems
If the problems or bugs you describe are considered to be bugs, we want to
have the problems fixed.
There are no developers in the curl project that are paid to work on bugs.
All developers that take on reported bugs do this on a voluntary basis. We do
it out of an ambition to keep curl and libcurl excellent products and out of
pride.
Please do not assume that you can just lump over something to us and it then
magically gets fixed after some given time. Most often we need feedback and
help to understand what you have experienced and how to repeat a problem.
Then we may only be able to assist YOU to debug the problem and to track down
the proper fix.
We get reports from many people every month and each report can take a
considerable amount of time to really go to the bottom with.
## How to get a stack trace
First, you must make sure that you compile all sources with `-g` and that you
do not 'strip' the final executable. Try to avoid optimizing the code as well,
remove `-O`, `-O2` etc from the compiler options.
Run the program until it cores.
Run your debugger on the core file, like `<debugger> curl core`. `<debugger>`
should be replaced with the name of your debugger, in most cases that is
`gdb`, but `dbx` and others also occur.
When the debugger has finished loading the core file and presents you a
prompt, enter `where` (without quotes) and press return.
The list that is presented is the stack trace. If everything worked, it is
supposed to contain the chain of functions that were called when curl
crashed. Include the stack trace with your detailed bug report, it helps a
lot.
## Bugs in libcurl bindings
There are of course bugs in libcurl bindings. You should then primarily
approach the team that works on that particular binding and see what you can
do to help them fix the problem.
If you suspect that the problem exists in the underlying libcurl, then please
convert your program over to plain C and follow the steps outlined above.
## Bugs in old versions
The curl project typically releases new versions every other month, and we
fix several hundred bugs per year. For a huge table of releases, number of
bug fixes and more, see: https://curl.se/docs/releases.html
The developers in the curl project do not have bandwidth or energy enough to
maintain several branches or to spend much time on hunting down problems in
old versions when chances are we already fixed them or at least that they have
changed nature and appearance in later versions.
When you experience a problem and want to report it, you really SHOULD
include the version number of the curl you are using when you experience the
issue. If that version number shows us that you are using an out-of-date curl,
you should also try out a modern curl version to see if the problem persists
or how/if it has changed in appearance.
Even if you cannot immediately upgrade your application/system to run the
latest curl version, you can most often at least run a test version or
experimental build or similar, to get this confirmed or not.
At times people insist that they cannot upgrade to a modern curl version, but
instead, they "just want the bug fixed". That is fine, just do not count on us
spending many cycles on trying to identify which single commit, if that is
even possible, that at some point in the past fixed the problem you are now
experiencing.
Security wise, it is almost always a bad idea to lag behind the current curl
versions by a lot. We keep discovering and reporting security problems
over time see you can see in [this
table](https://curl.se/docs/vulnerabilities.html)
# Bug fixing procedure
## What happens on first filing
When a new issue is posted in the issue tracker or on the mailing list, the
team of developers first needs to see the report. Maybe they took the day off,
maybe they are off in the woods hunting. Have patience. Allow at least a few
days before expecting someone to have responded.
In the issue tracker, you can expect that some labels are set on the issue to
help categorize it.
## First response
If your issue/bug report was not perfect at once (and few are), chances are
that someone asks follow-up questions. Which version did you use? Which
options did you use? How often does the problem occur? How can we reproduce
this problem? Which protocols does it involve? Or perhaps much more specific
and deep diving questions. It all depends on your specific issue.
You should then respond to these follow-up questions and provide more info
about the problem, so that we can help you figure it out. Or maybe you can
help us figure it out. An active back-and-forth communication is important
and the key for finding a cure and landing a fix.
## Not reproducible
We may require further work from you who actually see or experience the
problem if we cannot reproduce it and cannot understand it even after having
gotten all the info we need and having studied the source code over again.
## Unresponsive
If the problem have not been understood or reproduced, and there is nobody
responding to follow-up questions or questions asking for clarifications or
for discussing possible ways to move forward with the task, we take that as a
strong suggestion that the bug is unimportant.
Unimportant issues are closed as inactive sooner or later as they cannot be
fixed. The inactivity period (waiting for responses) should not be shorter
than two weeks but may extend months.
## Lack of time/interest
Bugs that are filed and are understood can unfortunately end up in the
"nobody cares enough about it to work on it" category. Such bugs are
perfectly valid problems that *should* get fixed but apparently are not. We
try to mark such bugs as `KNOWN_BUGS material` after a time of inactivity and
if no activity is noticed after yet some time those bugs are added to the
`KNOWN_BUGS` document and are closed in the issue tracker.
## `KNOWN_BUGS`
This is a list of known bugs. Bugs we know exist and that have been pointed
out but that have not yet been fixed. The reasons for why they have not been
fixed can involve anything really, but the primary reason is that nobody has
considered these problems to be important enough to spend the necessary time
and effort to have them fixed.
The `KNOWN_BUGS` items are always up for grabs and we love the ones who bring
one of them back to life and offer solutions to them.
The `KNOWN_BUGS` document has a sibling document known as `TODO`.
## `TODO`
Issues that are filed or reported that are not really bugs but more missing
features or ideas for future improvements and so on are marked as
*enhancement* or *feature-request* and get added to the `TODO` document and
the issues are closed. We do not keep TODO items open in the issue tracker.
The `TODO` document is full of ideas and suggestions of what we can add or
fix one day. You are always encouraged and free to grab one of those items and
take up a discussion with the curl development team on how that could be
implemented or provided in the project so that you can work on ticking it odd
that document.
If an issue is rather a bug and not a missing feature or functionality, it is
listed in `KNOWN_BUGS` instead.
## Closing off stalled bugs
The [issue and pull request trackers](https://github.com/curl/curl) only hold
"active" entries open (using a non-precise definition of what active actually
is, but they are at least not completely dead). Those that are abandoned or
in other ways dormant are closed and sometimes added to `TODO` and
`KNOWN_BUGS` instead.
This way, we only have "active" issues open on GitHub. Irrelevant issues and
pull requests do not distract developers or casual visitors.

## curl cipher options
A TLS handshake involves many parameters which take part in the negotiation
between client and server in order to agree on the TLS version and set of
algorithms to use for a connection.
What has become known as a "cipher" or better "cipher suite" in TLS
are names for specific combinations of
[key exchange](https://en.wikipedia.org/wiki/Key_exchange),
[bulk encryption](https://en.wikipedia.org/wiki/Link_encryption),
[message authentication code](https://en.wikipedia.org/wiki/Message_authentication_code)
and with TLSv1.3 the
[authenticated encryption](https://en.wikipedia.org/wiki/Authenticated_encryption).
In addition, there are other parameters that influence the TLS handshake, like
[DHE](https://en.wikipedia.org/wiki/Diffie%e2%80%93Hellman_key_exchange) "groups"
and [ECDHE](https://en.wikipedia.org/wiki/Elliptic-curve_Diffie%e2%80%93Hellman)
with its "curves".
### History
curl's way of letting users configure these settings closely followed OpenSSL
in its API. TLS learned new parameters, OpenSSL added new API functions and
curl added command line options.
Several other TLS backends followed the OpenSSL approach, more or less closely,
and curl maps the command line options to these TLS backends. Some TLS
backends do not support all of it and command line options are either
ignored or lead to an error.
Many examples below show the OpenSSL-like use of these options. GnuTLS
however chose a different approach. These are described in a separate
section further below.
## ciphers, the OpenSSL way
With curl's option
[`--tls13-ciphers`](https://curl.se/docs/manpage.html#--tls13-ciphers)
or
[`CURLOPT_TLS13_CIPHERS`](https://curl.se/libcurl/c/CURLOPT_TLS13_CIPHERS.html)
users can control which cipher suites to consider when negotiating TLS 1.3
connections. With option
[`--ciphers`](https://curl.se/docs/manpage.html#--ciphers)
or
[`CURLOPT_SSL_CIPHER_LIST`](https://curl.se/libcurl/c/CURLOPT_SSL_CIPHER_LIST.html)
users can control which cipher suites to consider when negotiating
TLS 1.2 (1.1, 1.0) connections.
By default, curl may negotiate TLS 1.3 and TLS 1.2 connections, so the cipher
suites considered when negotiating a TLS connection are a union of the TLS 1.3
and TLS 1.2 cipher suites. If you want curl to consider only TLS 1.3 cipher
suites for the connection, you have to set the minimum TLS version to 1.3 by
using [`--tlsv1.3`](https://curl.se/docs/manpage.html#--tlsv13)
or [`CURLOPT_SSLVERSION`](https://curl.se/libcurl/c/CURLOPT_SSLVERSION.html)
with `CURL_SSLVERSION_TLSv1_3`.
Both the TLS 1.3 and TLS 1.2 cipher options expect a list of cipher suites
separated by colons (`:`). This list is parsed opportunistically, cipher suites
that are not recognized or implemented are ignored. As long as there is at
least one recognized cipher suite in the list, the list is considered valid.
For both the TLS 1.3 and TLS 1.2 cipher options, the order in which the
cipher suites are specified determine the preference of them. When negotiating
a TLS connection the server picks a cipher suite from the intersection of the
cipher suites supported by the server and the cipher suites sent by curl. If
the server is configured to honor the client's cipher preference, the first
common cipher suite in the list sent by curl is chosen.
### TLS 1.3 cipher suites
Setting TLS 1.3 cipher suites is supported by curl with
OpenSSL (1.1.1+, curl 7.61.0+), LibreSSL (3.4.1+, curl 8.3.0+),
wolfSSL (curl 8.10.0+) and mbedTLS (3.6.0+, curl 8.10.0+).
The list of cipher suites that can be used for the `--tls13-ciphers` option:
```
TLS_AES_128_GCM_SHA256
TLS_AES_256_GCM_SHA384
TLS_CHACHA20_POLY1305_SHA256
TLS_AES_128_CCM_SHA256
TLS_AES_128_CCM_8_SHA256
```

In addition to above list the following cipher suites can be used:
`TLS_SM4_GCM_SM3` `TLS_SM4_CCM_SM3` `TLS_SHA256_SHA256` `TLS_SHA384_SHA384`.
Usage of these cipher suites is not recommended. (The last two cipher suites
are NULL ciphers, offering no encryption whatsoever.)
### TLS 1.2 (1.1, 1.0) cipher suites
Setting TLS 1.2 cipher suites is supported by curl with OpenSSL, LibreSSL,
BoringSSL, mbedTLS (curl 8.8.0+), wolfSSL (curl 7.53.0+). Schannel does not
support setting cipher suites directly, but does support setting algorithms
(curl 7.61.0+), see Schannel notes below.
For TLS 1.2 cipher suites there are multiple naming schemes, the two most used
are with OpenSSL names (e.g. `ECDHE-RSA-AES128-GCM-SHA256`) and IANA names
(e.g. `TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256`). IANA names of TLS 1.2 cipher
suites look similar to TLS 1.3 cipher suite names, to distinguish them note
that TLS 1.2 names contain `_WITH_`, while TLS 1.3 names do not. When setting
TLS 1.2 cipher suites with curl it is recommended that you use OpenSSL names
as these are most widely recognized by the supported SSL backends.
The complete list of cipher suites that may be considered for the `--ciphers`
option is extensive, it consists of more than 300 ciphers suites. However,
nowadays for most of them their usage is discouraged, and support for a lot of
them have been removed from the various SSL backends, if ever implemented at
all.
A shortened list (based on [recommendations by
Mozilla](https://wiki.mozilla.org/Security/Server_Side_TLS)) of cipher suites,
which are (mostly) supported by all SSL backends, that can be used for the
`--ciphers` option:
```
ECDHE-ECDSA-AES128-GCM-SHA256
ECDHE-RSA-AES128-GCM-SHA256
ECDHE-ECDSA-AES256-GCM-SHA384
ECDHE-RSA-AES256-GCM-SHA384
ECDHE-ECDSA-CHACHA20-POLY1305
ECDHE-RSA-CHACHA20-POLY1305
DHE-RSA-AES128-GCM-SHA256
DHE-RSA-AES256-GCM-SHA384
DHE-RSA-CHACHA20-POLY1305
ECDHE-ECDSA-AES128-SHA256
ECDHE-RSA-AES128-SHA256
ECDHE-ECDSA-AES128-SHA
ECDHE-RSA-AES128-SHA
ECDHE-ECDSA-AES256-SHA384
ECDHE-RSA-AES256-SHA384
ECDHE-ECDSA-AES256-SHA
ECDHE-RSA-AES256-SHA
DHE-RSA-AES128-SHA256
DHE-RSA-AES256-SHA256
AES128-GCM-SHA256
AES256-GCM-SHA384
AES128-SHA256
AES256-SHA256
AES128-SHA
AES256-SHA
DES-CBC3-SHA
```
See this [list](https://github.com/curl/curl/blob/master/docs/CIPHERS-TLS12.md)
for a complete list of TLS 1.2 cipher suites.
#### OpenSSL notes
In addition to specifying a list of cipher suites, OpenSSL also accepts a
format with specific cipher strings (like `TLSv1.2`, `AESGCM`, `CHACHA20`) and
`!`, `-` and `+` operators. Refer to the
[OpenSSL cipher documentation](https://docs.openssl.org/master/man1/openssl-ciphers/#cipher-list-format)
for further information on that format.
#### Schannel notes
Schannel does not support setting individual TLS 1.2 cipher suites directly.
It only allows the enabling and disabling of encryption algorithms. These are
in the form of `CALG_xxx`, see the [Schannel `ALG_ID`
documentation](https://docs.microsoft.com/windows/desktop/SecCrypto/alg-id)
for a list of these algorithms. Also, (since curl 7.77.0)
`SCH_USE_STRONG_CRYPTO` can be given to pass that flag to Schannel, lookup the
[documentation for the Windows version in
use](https://learn.microsoft.com/en-us/windows/win32/secauthn/cipher-suites-in-schannel)
to see how that affects the cipher suite selection. When not specifying the
`--ciphers` and `--tls13-ciphers` options curl passes this flag by default.
### Examples
```sh
curl \
--tls13-ciphers TLS_AES_128_GCM_SHA256:TLS_CHACHA20_POLY1305_SHA256 \
--ciphers ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-GCM-SHA256:\
ECDHE-ECDSA-CHACHA20-POLY1305:ECDHE-RSA-CHACHA20-POLY1305 \
https://example.com/
```
Restrict ciphers to `aes128-gcm` and `chacha20`. Works with OpenSSL, LibreSSL,
mbedTLS and wolfSSL.
```sh
curl \
--tlsv1.3 \
--tls13-ciphers TLS_AES_128_GCM_SHA256:TLS_CHACHA20_POLY1305_SHA256 \
https://example.com/
```
Restrict to only TLS 1.3 with `aes128-gcm` and `chacha20` ciphers. Works with
OpenSSL, LibreSSL, mbedTLS, wolfSSL and Schannel.
```sh
curl \
--ciphers ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-GCM-SHA256:\
ECDHE-ECDSA-CHACHA20-POLY1305:ECDHE-RSA-CHACHA20-POLY1305 \
https://example.com/
```
Restrict TLS 1.2 ciphers to `aes128-gcm` and `chacha20`, use default TLS 1.3
ciphers (if TLS 1.3 is available). Works with OpenSSL, LibreSSL, BoringSSL,
mbedTLS and wolfSSL.
## ciphers, the GnuTLS way
With GnuTLS, curl allows configuration of all TLS parameters via option
[`--ciphers`](https://curl.se/docs/manpage.html#--ciphers)
or
[`CURLOPT_SSL_CIPHER_LIST`](https://curl.se/libcurl/c/CURLOPT_SSL_CIPHER_LIST.html)
only. The option
[`--tls13-ciphers`](https://curl.se/docs/manpage.html#--tls13-ciphers)
or
[`CURLOPT_TLS13_CIPHERS`](https://curl.se/libcurl/c/CURLOPT_TLS13_CIPHERS.html)
is being ignored.
`--ciphers` is used to set the GnuTLS **priority string** in
the following way:
* When the set string starts with '+', '-' or '!' it is *appended* to the
priority string libcurl itself generates (separated by ':'). This initial
priority depends other settings such as CURLOPT_SSLVERSION(3),
CURLOPT_TLSAUTH_USERNAME(3) (for SRP) or if HTTP/3 (QUIC)
is being negotiated.
* Otherwise, the set string fully *replaces* the libcurl generated one. While
giving full control to the application, the set priority needs to
provide for everything the transfer may need to negotiate. Example: if
the set priority only allows TLSv1.2, all HTTP/3 attempts fail.
Users may specify via `--ciphers` anything that GnuTLS supports: ciphers,
key exchange, MAC, compression, TLS versions, signature algorithms, groups,
elliptic curves, certificate types. In addition, GnuTLS has a variety of
other keywords that tweak its operations. Applications or a system
may define new alias names for priority strings that can then be used here.
Since the order of items in priority strings is significant, it makes no
sense for curl to puzzle other ssl options somehow together. `--ciphers`
is the single way to change priority.
### Examples
```sh
curl \
--ciphers '-CIPHER_ALL:+AES-128-GCM:+CHACHA20-POLY1305' \
https://example.com/
```
Restrict ciphers to `aes128-gcm` and `chacha20` in GnuTLS.
```sh
curl \
--ciphers 'NORMAL:-VERS-ALL:+TLS1.3:-AES-256-GCM' \
https://example.com/
```
Restrict to only TLS 1.3 without the `aes256-gcm` cipher.
```sh
curl \
--ciphers 'NORMAL:-VERS-ALL:+TLS1.2:-CIPHER_ALL:+CAMELLIA-128-GCM' \
https://example.com/
```
Restrict to only TLS 1.2 with the `CAMELLIA-128-GCM` cipher.

# How to do code reviews for curl
Anyone and everyone is encouraged and welcome to review code submissions in
curl. This is a guide on what to check for and how to perform a successful
code review.
## All submissions should get reviewed
All pull requests and patches submitted to the project should be reviewed by
at least one experienced curl maintainer before that code is accepted and
merged.
## Let the tools and tests take the first rounds
On initial pull requests, let the tools and tests do their job first and then
start out by helping the submitter understand the test failures and tool
alerts.
## How to provide feedback to author
Be nice. Ask questions. Provide examples or suggestions of improvements.
Assume the best intentions. Remember language barriers.
All first-time contributors can become regulars. Let's help them go there.
## Is this a change we want?
If this is not a change that seems to be aligned with the project's path
forward and as such cannot be accepted, inform the author about this sooner
rather than later. Do it gently and explain why and possibly what could be
done to make it more acceptable.
## API/ABI stability or changed behavior
Changing the API and the ABI may be fine in a change but it needs to be done
deliberately and carefully. If not, a reviewer must help the author to realize
the mistake.
curl and libcurl are similarly strict on not modifying existing behavior. API
and ABI stability is not enough, the behavior should also remain intact as far
as possible.
## Code style
Most code style nits are detected by checksrc but not all. Only leave remarks
on style deviation once checksrc does not find anymore.
Minor nits from fresh submitters can also be handled by the maintainer when
merging, in case it seems like the submitter is not clear on what to do. We
want to make the process fun and exciting for new contributors.
## Encourage consistency
Make sure new code is written in a similar style as existing code. Naming,
logic, conditions, etc.
## Are pointers always non-NULL?
If a function or code rely on pointers being non-NULL, take an extra look if
that seems to be a fair assessment.
## Asserts
Conditions that should never be false can be verified with `DEBUGASSERT()`
calls to get caught in tests and debugging easier, while not having an impact
on final or release builds.
## Memory allocation
Can the mallocs be avoided? Do not introduce mallocs in any hot paths. If
there are (new) mallocs, can they be combined into fewer calls?
Are all allocations handled in error paths to avoid leaks and crashes?
## Thread-safety
We do not like static variables as they break thread-safety and prevent
functions from being reentrant.
## Should features be `#ifdef`ed?
Features and functionality may not be present everywhere and should therefore
be `#ifdef`ed. Additionally, some features should be possible to switch on/off
in the build.
Write `#ifdef`s to be as little of a "maze" as possible.
## Does it look portable enough?
curl runs "everywhere". Does the code take a reasonable stance and enough
precautions to be possible to build and run on most platforms?
Remember that we live by C89 restrictions.
## Tests and testability
New features should be added in conjunction with one or more test cases.
Ideally, functions should also be written so that unit tests can be done to
test individual functions.
## Documentation
New features or changes to existing functionality **must** be accompanied by
updated documentation. Submitting that in a separate follow-up pull request is
not OK. A code review must also verify that the submitted documentation update
matches the code submission.
English is not everyone's first language, be mindful of this and help the
submitter improve the text if it needs a rewrite to read better.
## Code should not be hard to understand
Source code should be written to maximize readability and be easy to
understand.
## Functions should not be large
A single function should never be large as that makes it hard to follow and
understand all the exit points and state changes. Some existing functions in
curl certainly violate this ground rule but when reviewing new code we should
propose splitting into smaller functions.
## Duplication is evil
Anything that looks like duplicated code is a red flag. Anything that seems to
introduce code that we *should* already have or provide needs a closer check.
## Sensitive data
When credentials are involved, take an extra look at what happens with this
data. Where it comes from and where it goes.
## Variable types differ
`size_t` is not a fixed size. `time_t` can be signed or unsigned and have
different sizes. Relying on variable sizes is a red flag.
Also remember that endianness and >= 32-bit accesses to unaligned addresses
are problematic areas.
## Integer overflows
Be careful about integer overflows. Some variable types can be either 32-bit
or 64-bit. Integer overflows must be detected and acted on *before* they
happen.
## Dangerous use of functions
Maybe use of `realloc()` should rather use the dynbuf functions?
Do not allow new code that grows buffers without using dynbuf.
Use of C functions that rely on a terminating zero must only be used on data
that really do have a null-terminating zero.
## Dangerous "data styles"
Make extra precautions and verify that memory buffers that need a terminating
zero always have exactly that. Buffers *without* a null-terminator must not be
used as input to string functions.
# Commit messages
Tightly coupled with a code review is making sure that the commit message is
good. It is the responsibility of the person who merges the code to make sure
that the commit message follows our standard (detailed in the
[CONTRIBUTE](https://curl.se/dev/contribute.html) document). This includes
making sure the PR identifies related issues and giving credit to reporters
and helpers.

# Contributing to the curl project
This document is intended to offer guidelines on how to best contribute to the
curl project. This concerns new features as well as corrections to existing
flaws or bugs.
## Join the Community
Skip over to [https://curl.se/mail/](https://curl.se/mail/) and join
the appropriate mailing list(s). Read up on details before you post
questions. Read this file before you start sending patches. We prefer
questions sent to and discussions being held on the mailing list(s), not sent
to individuals.
Before posting to one of the curl mailing lists, please read up on the
[mailing list etiquette](https://curl.se/mail/etiquette.html).
We also hang out on IRC in #curl on libera.chat
If you are at all interested in the code side of things, consider clicking
'watch' on the [curl repository on GitHub](https://github.com/curl/curl) to be
notified of pull requests and new issues posted there.
## License and copyright
When contributing with code, you agree to put your changes and new code under
the same license curl and libcurl is already using unless stated and agreed
otherwise.
If you add a larger piece of code, you can opt to make that file or set of
files to use a different license as long as they do not enforce any changes to
the rest of the package and they make sense. Such "separate parts" can not be
GPL licensed (as we do not want copyleft to affect users of libcurl) but they
must use "GPL compatible" licenses (as we want to allow users to use libcurl
properly in GPL licensed environments).
When changing existing source code, you do not alter the copyright of the
original file(s). The copyright is still owned by the original creator(s) or
those who have been assigned copyright by the original author(s).
By submitting a patch to the curl project, you are assumed to have the right
to the code and to be allowed by your employer or whatever to hand over that
patch/code to us. We credit you for your changes as far as possible, to give
credit but also to keep a trace back to who made what changes. Please always
provide us with your full real name when contributing,
## What To Read
Source code, the man pages, the [INTERNALS
document](https://curl.se/dev/internals.html),
[TODO](https://curl.se/docs/todo.html),
[KNOWN_BUGS](https://curl.se/docs/knownbugs.html) and the [most recent
changes](https://curl.se/dev/sourceactivity.html) in git. Just lurking on the
[curl-library mailing list](https://curl.se/mail/list.cgi?list=curl-library)
gives you a lot of insights on what's going on right now. Asking there is a
good idea too.
## Write a good patch
### Follow code style
When writing C code, follow the
[CODE_STYLE](https://curl.se/dev/code-style.html) already established in
the project. Consistent style makes code easier to read and mistakes less
likely to happen. Run `make checksrc` before you submit anything, to make sure
you follow the basic style. That script does not verify everything, but if it
complains you know you have work to do.
### Non-clobbering All Over
When you write new functionality or fix bugs, it is important that you do not
fiddle all over the source files and functions. Remember that it is likely
that other people have done changes in the same source files as you have and
possibly even in the same functions. If you bring completely new
functionality, try writing it in a new source file. If you fix bugs, try to
fix one bug at a time and send them as separate patches.
### Write Separate Changes
It is annoying when you get a huge patch from someone that is said to fix 11
odd problems, but discussions and opinions do not agree with 10 of them - or 9
of them were already fixed in a different way. Then the person merging this
change needs to extract the single interesting patch from somewhere within the
huge pile of source, and that creates a lot of extra work.
Preferably, each fix that corrects a problem should be in its own patch/commit
with its own description/commit message stating exactly what they correct so
that all changes can be selectively applied by the maintainer or other
interested parties.
Also, separate changes enable bisecting much better for tracking problems
and regression in the future.
### Patch Against Recent Sources
Please try to get the latest available sources to make your patches against.
It makes the lives of the developers so much easier. The best is if you get
the most up-to-date sources from the git repository, but the latest release
archive is quite OK as well.
### Documentation
Writing docs is dead boring and one of the big problems with many open source
projects but someone's gotta do it. It makes things a lot easier if you submit
a small description of your fix or your new features with every contribution
so that it can be swiftly added to the package documentation.
Documentation is mostly provided as manpages or plain ASCII files. The
manpages are rendered from their source files that are usually written using
markdown. Most HTML files on the website and in the release archives are
generated from corresponding markdown and ASCII files.
### Test Cases
Since the introduction of the test suite, we can quickly verify that the main
features are working as they are supposed to. To maintain this situation and
improve it, all new features and functions that are added need to be tested in
the test suite. Every feature that is added should get at least one valid test
case that verifies that it works as documented. If every submitter also posts
a few test cases, it does not end up a heavy burden on a single person.
If you do not have test cases or perhaps you have done something that is hard
to write tests for, do explain exactly how you have otherwise tested and
verified your changes.
# Submit Your Changes
## Get your changes merged
Ideally you file a [pull request on
GitHub](https://github.com/curl/curl/pulls), but you can also send your plain
patch to [the curl-library mailing
list](https://curl.se/mail/list.cgi?list=curl-library).
If you opt to post a patch on the mailing list, chances are someone converts
it into a pull request for you, to have the CI jobs verify it proper before it
can be merged. Be prepared that some feedback on the proposed change might
then come on GitHub.
Your changes be reviewed and discussed and you are expected to correct flaws
pointed out and update accordingly, or the change risks stalling and
eventually just getting deleted without action. As a submitter of a change,
you are the owner of that change until it has been merged.
Respond on the list or on GitHub about the change and answer questions and/or
fix nits/flaws. This is important. We take lack of replies as a sign that you
are not anxious to get your patch accepted and we tend to simply drop such
changes.
## About pull requests
With GitHub it is easy to send a [pull
request](https://github.com/curl/curl/pulls) to the curl project to have
changes merged.
We strongly prefer pull requests to mailed patches, as it makes it a proper
git commit that is easy to merge and they are easy to track and not that easy
to lose in the flood of many emails, like they sometimes do on the mailing
lists.
Every pull request submitted is automatically tested in several different
ways. [See the CI document for more
information](https://github.com/curl/curl/blob/master/docs/tests/CI.md).
Sometimes the tests fail due to a dependency service temporarily being offline
or otherwise unavailable, e.g. package downloads. In this case you can just
try to update your pull requests to rerun the tests later as described below.
You can update your pull requests by pushing new commits or force-pushing
changes to existing commits. Force-pushing an amended commit without any
actual content changed also allows you to retrigger the tests for that commit.
When you adjust your pull requests after review, consider squashing the
commits so that we can review the full updated version more easily.
A pull request sent to the project might get labeled `needs-votes` by a
project maintainer. This label means that in addition to meeting all other
checks and qualifications this pull request must also receive more "votes" of
user support. More signs that people want this to happen. It could be in the
form of messages saying so, or thumbs-up reactions on GitHub.
## When the pull request is approved
If it does not seem to get approved when you think it is ready - feel free to
ask for approval.
Once your pull request has been approved it can be merged by a maintainer.
For new features, or changes, we require that the *feature window* is open for
the pull request to be merged. This is typically a three week period that
starts ten days after a previous release. New features submitted as pull
requests while the window is closed simply have to wait until it opens to get
merged.
If time passes without your approved pull request gets merged: feel free to
ask what more you can do to make it happen.
## Making quality changes
Make the patch against as recent source versions as possible.
If you have followed the tips in this document and your patch still has not
been incorporated or responded to after some weeks, consider resubmitting it
to the list or better yet: change it to a pull request.
## Commit messages
How to write git commit messages in the curl project.
---- start ----
[area]: [short line describing the main effect]
-- empty line --
[full description, no wider than 72 columns that describes as much as
possible as to why this change is made, and possibly what things
it fixes and everything else that is related,
-- end --
The first line is a succinct description of the change and should ideally work
as a single line in the RELEASE NOTES.
- use the imperative, present tense: **change** not "changed" nor "changes"
- do not capitalize the first letter
- no period (.) at the end
The `[area]` in the first line can be `http2`, `cookies`, `openssl` or
similar. There is no fixed list to select from but using the same "area" as
other related changes could make sense.
## Commit message keywords
Use the following ways to improve the message and provide pointers to related
work.
- `Follow-up to {shorthash}` - if this fixes or continues a previous commit;
add a `Ref:` that commit's PR or issue if it is not a small, obvious fix;
followed by an empty line
- `Bug: URL` to the source of the report or more related discussion; use
`Fixes` for GitHub issues instead when that is appropriate.
- `Approved-by: John Doe` - credit someone who approved the PR.
- `Authored-by: John Doe` - credit the original author of the code; only use
this if you cannot use `git commit --author=...`.
- `Signed-off-by: John Doe` - we do not use this, but do not bother removing
it.
- `whatever-else-by:` credit all helpers, finders, doers; try to use one of
the following keywords if at all possible, for consistency: `Acked-by:`,
`Assisted-by:`, `Co-authored-by:`, `Found-by:`, `Reported-by:`,
`Reviewed-by:`, `Suggested-by:`, `Tested-by:`.
- `Ref: #1234` - if this is related to a GitHub issue or PR, possibly one that
has already been closed.
- `Ref: URL` to more information about the commit; use `Bug:` instead for a
reference to a bug on another bug tracker]
- `Fixes #1234` - if this fixes a GitHub issue; GitHub closes the issue once
this commit is merged.
- `Closes #1234` - if this merges a GitHub PR; GitHub closes the PR once this
commit is merged.
Do not forget to use commit with `--author` if you commit someone else's work,
and make sure that you have your own user and email setup correctly in git
before you commit.
Add whichever header lines as appropriate, with one line per person if more
than one person was involved. There is no need to credit yourself unless you
are using `--author` which hides your identity. Do not include people's email
addresses in headers to avoid spam, unless they are already public from a
previous commit; saying `{userid} on github` is OK.
## Push Access
If you are a frequent contributor, you may be given push access to the git
repository and then you are able to push your changes straight into the git
repository instead of sending changes as pull requests or by mail as patches.
Just ask if this is what you would want. You are required to have posted
several high quality patches first, before you can be granted push access.

# Update copyright and license information
There is a CI job called **REUSE compliance / check** that runs on every pull
request and commit to verify that the *REUSE state* of all files are still
fine.
This means that all files need to have their license and copyright information
clearly stated. Ideally by having the standard curl source code header, with
the `SPDX-License-Identifier` included. If the header does not work, you can
use a smaller header or add the information for a specific file to the
`REUSE.toml` file.
You can manually verify the copyright and compliance status by running the
[REUSE helper tool](https://github.com/fsfe/reuse-tool): `reuse lint`
# On AI use in curl
Guidelines for AI use when contributing to curl.
## For security reports and other issues
If you asked an AI tool to find problems in curl, you **must** make sure to
reveal this fact in your report.
You must also double-check the findings carefully before reporting them to us
to validate that the issues are indeed existing and working exactly as the AI
says. AI-based tools frequently generate inaccurate or fabricated results.
Further: it is *rarely* a good idea to just copy and paste an AI generated
report to the project. Those generated reports typically are too wordy and
rarely to the point (in addition to the common fabricated details). If you
actually find a problem with an AI and you have verified it yourself to be
true: write the report yourself and explain the problem as you have learned
it. This makes sure the AI-generated inaccuracies and invented issues are
filtered out early before they waste more people's time.
As we take security reports seriously, we investigate each report with
priority. This work is both time and energy consuming and pulls us away from
doing other meaningful work. Fake and otherwise made up security problems
effectively prevent us from doing real project work and make us waste time and
resources.
We ban users immediately who submit made up fake reports to the project.
## For pull requests
When contributing content to the curl project, you give us permission to use
it as-is and you must make sure you are allowed to distribute it to us. By
submitting a change to us, you agree that the changes can and should be
adopted by curl and get redistributed under the curl license. Authors should
be explicitly aware that the burden is on them to ensure no unlicensed code is
submitted to the project.
This is independent if AI is used or not.
When contributing a pull request you should of course always make sure that
the proposal is good quality and a best effort that follows our guidelines. A
basic rule of thumb is that if someone can spot that the contribution was made
with the help of AI, you have more work to do.
We can accept code written with the help of AI into the project, but the code
must still follow coding standards, be written clearly, be documented, feature
test cases and adhere to all the normal requirements we have.
## For translation
Translation services help users write reports, texts and documentation in
non-native languages and we encourage and welcome such contributors and
contributions.
As AI-based translation tools sometimes have a way to make the output sound a
little robotic and add an "AI tone" to the text, you may want to consider
mentioning that you used such a tool. Failing to do so risks that maintainers
wrongly dismiss translated texts as AI slop.

# curldown
A markdown-like syntax for libcurl man pages.
## Purpose
A text format for writing libcurl documentation in the shape of man pages.
Make it easier for users to contribute and write documentation. A format that
is easier on the eye in its source format.
Make it harder to do syntactical mistakes.
Use a format that allows creating man pages that end up looking exactly like
the man pages did when we wrote them in nroff format.
Take advantage of the fact that people these days are accustomed to markdown
by using a markdown-like syntax.
This allows us to fix issues in the nroff format easier since now we generate
them. For example: escaping minus to prevent them from being turned into
Unicode by man.
Generate nroff output that looks (next to) *identical* to the previous files,
so that the look, existing test cases, HTML conversions, existing
infrastructure etc remain mostly intact.
Contains meta-data in a structured way to allow better output (for example the
see also information) and general awareness of what the file is about.
## File extension
Since curldown looks similar to markdown, we use `.md` extensions on the
files.
## Conversion
Convert **from curldown to nroff** with `cd2nroff`. Generates nroff man pages.
Convert **from nroff to curldown** with `nroff2cd`. This is only meant to be
used for the initial conversion to curldown and should ideally never be needed
again.
Convert, check or clean up an existing curldown to nicer, better, cleaner
curldown with **cd2cd**.
Mass-convert all curldown files to nroff in specified directories with
`cdall`:
cdall [dir1] [dir2] [dir3] ..
## Known issues
The `cd2nroff` tool does not yet handle *italics* or **bold** where the start
and the end markers are used on separate lines.
The `nroff2cd` tool generates code style quotes for all `.fi` sections since
the nroff format does not carry a distinction.
# Format
Each curldown starts with a header with meta-data:
---
c: Copyright (C) Daniel Stenberg, <daniel@haxx.se>, et al.
SPDX-License-Identifier: curl
Title: CURLOPT_AWS_SIGV4
Section: 3
Source: libcurl
Protocol:
- HTTP
See-also:
- CURLOPT_HEADEROPT (3)
- CURLOPT_HTTPAUTH (3)
TLS-backend:
- [name]
Added-in: [version or "n/a"]
---
All curldown files *must* have all the headers present and at least one
`See-also:` entry specified.
If the man page is for section 3 (library related). The `Protocol` list must
contain at least one protocol, which can be `*` if the option is virtually for
everything. If `*` is used, it must be the only listed protocol. Recognized
protocols are either URL schemes (in uppercase), `TLS` or `TCP`.
If the `Protocol` list contains `TLS`, then there must also be a `TLS-backend`
list, specifying `All` or a list of what TLS backends that work with this
option. The available TLS backends are:
- `GnuTLS`
- `mbedTLS`
- `OpenSSL` (also covers BoringSSL, LibreSSL, quictls, AWS-LC and AmiSSL)
- `rustls`
- `Schannel`
- `wolfSSL`
- `All`: all TLS backends
Following the header in the file, is the manual page using markdown-like
syntax:
~~~
# NAME
a page - this is a page describing something
# SYNOPSIS
~~~c
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_AWS_SIGV4, char *param);
~~~
~~~
Quoted source code should start with `~~~c` and end with `~~~` while regular
quotes can start with `~~~` or just be indented with 4 spaces.
Headers at top-level `#` get converted to `.SH`.
`nroff2cd` supports the `##` next level header which gets converted to `.IP`.
Write bold words or phrases within `**` like:
This is a **bold** word.
Write italics like:
This is *italics*.
Due to how man pages do not support backticks especially formatted, such
occurrences in the source are instead just using italics in the generated
output:
This `word` appears in italics.
When generating the nroff output, the tooling removes superfluous newlines,
meaning they can be used freely in the source file to make the text more
readable.
To make sure curldown documents render correctly as markdown, all literal
occurrences of `<` or `>` need to be escaped by a leading backslash.
## Generating contents
`# %PROTOCOLS%` - inserts a **PROTOCOLS** section based on the metadata
provided in the header.
`# %AVAILABILITY%` - inserts an **AVAILABILITY** section based on the metadata
provided in the header.
## Symbols
All mentioned curl symbols that have their own man pages, like
`curl_easy_perform(3)` are automatically rendered using italics in the output
without having to enclose it with asterisks. This helps ensuring that they get
converted to links properly later in the HTML version on the website, as
converted with `roffit`. This makes the curldown text easier to read even when
mentioning many curl symbols.
This auto-linking works for patterns matching `(lib|)curl[^ ]*(3)`.

# Items to be removed from future curl releases
If any of these deprecated features is a cause for concern for you, please
email the
[curl-library mailing list](https://lists.haxx.se/listinfo/curl-library)
as soon as possible and explain to us why this is a problem for you and
how your use case cannot be satisfied properly using a workaround.
## Nothing
Nothing is currently scheduled to be removed.
## msh3 support
The msh3 backed for QUIC and HTTP/3 was introduced in April 2022 but has never
been made to work properly. It has seen no visible traction or developer
activity from the msh3 main author (or anyone else seemingly interested) in
two years. As a non-functional backend, it only adds friction and "weight" to
the development and maintenance.
Meanwhile, we have a fully working backend in the ngtcp2 one and we have two
fully working backends in OpenSSL-QUIC and quiche well on their way of ending
their experimental status in a future.
We remove msh3 support from the curl source tree in July 2025.
## winbuild build system
curl drops support for the winbuild build method after September 2025.
We recommend migrating to CMake. See the migration guide in
`docs/INSTALL-CMAKE.md`.
## Windows CE
Windows CE "mainstream support" ended on October 9, 2018, and "Extended
Support" ended on October 10, 2023.
curl drops all support in November 2025.
## VS2008
curl drops support for getting built with Microsoft Visual Studio 2008 in
November 2025.
The only reason we kept support for this version is for Windows CE - and we
intend to remove support for that Operating System in this time frame as well.
Bumping the minimum to VS2010. VS2008 is a pain to support.
Previous discussion and details: https://github.com/curl/curl/discussions/15972
## Past removals
- axTLS (removed in 7.63.0)
- Pipelining (removed in 7.65.0)

# curl distros
<!-- markdown-link-check-disable -->
Lots of organizations distribute curl packages to end users. This is a
collection of pointers to where to learn more about curl on and with each
distro. Those marked *Rolling Release* typically run the latest version of curl
and are therefore less likely to have back-ported patches to older versions.
We discuss curl distro issues, patches and collaboration on the [curl-distros
mailing list](https://lists.haxx.se/listinfo/curl-distros) ([list
archives](https://curl.se/mail/list.cgi?list=curl-distros)).

# How to determine if an early patch release is warranted
In the curl project we do releases every 8 weeks. Unless we break the cycle
and do an early patch release.
We do frequent releases partly to always have the next release "not too far
away".
## Bugfix
During the release cycle, and especially in the beginning of a new cycle (the
so-called "cool down" period), there are times when a bug is reported and
after it has been subsequently fixed correctly, the question might be asked:
is this bug and associated fix important enough for an early patch release?
The question can only be properly asked when a fix has been created and landed
in the git master branch.
## Early release
An early patch release means that we ship a new, complete and full release
called `major.minor.patch` where the `patch` part is increased by one since
the previous release. A curl release is a curl release. There is no small or
big and we never release just a patch. There is only "release".
## Questions to ask
- Is there a security advisory rated high or critical?
- Is there a data corruption bug?
- Did the bug cause an API/ABI breakage?
- Does the problem annoy a significant share of the user population?
If the answer is yes to one or more of the above, an early release might be
warranted.
More questions to ask ourselves when doing the assessment if the answers to
the three ones above are all 'no'.
- Does the bug cause curl to prematurely terminate?
- How common is the affected buggy option/feature/protocol/platform to get
used?
- How large is the estimated impacted user base?
- Does the bug block something crucial for applications or other adoption of
curl "out there" ?
- Does the bug cause problems for curl developers or others on "the curl
team" ?
- Is the bug limited to the curl tool only? That might have a smaller impact
than a bug also present in libcurl.
- Is there a (decent) workaround?
- Is it a regression? Is the bug introduced in this release?
- Can the bug be fixed "easily" by applying a patch?
- Does the bug break the build? Most users do not build curl themselves.
- How long is it until the already scheduled next release?
- Can affected users safely rather revert to a former release until the next
scheduled release?
- Is it a performance regression with no functionality side-effects? If so it
has to be substantial.
## If an early release is deemed necessary
Unless done for security or similarly important reasons, an early release
should not be done within a week of the previous release.
This, to enable us to collect and bundle more fixes into the same release to
make the release more worthwhile for everyone and to allow more time for fixes
to settle and things to get tested. Getting a release in shape and done in
style is work that should not be rushed.

# Building curl with HTTPS-RR and ECH support
We have added support for ECH to curl. It can use HTTPS RRs published in the
DNS if curl uses DoH, or else can accept the relevant ECHConfigList values
from the command line. This works with OpenSSL, wolfSSL, BoringSSL, AWS-LC
or rustls-ffi as the TLS provider.
This feature is EXPERIMENTAL. DO NOT USE IN PRODUCTION.
This should however provide enough of a proof-of-concept to prompt an informed
discussion about a good path forward for ECH support in curl.
## OpenSSL Build
To build the OpenSSL project's ECH feature branch:
```bash
cd $HOME/code
git clone https://github.com/openssl/openssl
cd openssl
git checkout feature/ech
./config --libdir=lib --prefix=$HOME/code/openssl-local-inst
...stuff...
make -j8
...more stuff...
make install_sw
...a little bit of stuff...
```
To build curl ECH-enabled, making use of the above:
```bash
cd $HOME/code
git clone https://github.com/curl/curl
cd curl
autoreconf -fi
LDFLAGS="-Wl,-rpath,$HOME/code/openssl-local-inst/lib/" ./configure --with-ssl=$HOME/code/openssl-local-inst --enable-ech
...lots of output...
WARNING: ECH HTTPSRR enabled but marked EXPERIMENTAL...
make
...lots more output...
```
If you do not get that WARNING at the end of the ``configure`` command, then
ECH is not enabled, so go back some steps and re-do whatever needs re-doing:-)
If you want to debug curl then you should add ``--enable-debug`` to the
``configure`` command.
In a recent (2024-05-20) build on one machine, configure failed to find the
ECH-enabled SSL library, apparently due to the existence of
``$HOME/code/openssl-local-inst/lib/pkgconfig`` as a directory containing
various settings. Deleting that directory worked around the problem but may
not be the best solution.
## Using ECH and DoH
curl supports using DoH for A/AAAA lookups so it was relatively easy to add
retrieval of HTTPS RRs in that situation. To use ECH and DoH together:
```bash
cd $HOME/code/curl
LD_LIBRARY_PATH=$HOME/code/openssl ./src/curl --ech true --doh-url https://one.one.one.one/dns-query https://defo.ie/ech-check.php
...
SSL_ECH_STATUS: success <img src="greentick-small.png" alt="good" /> <br/>
...
```
The output snippet above is within the HTML for the webpage, when things work.
The above works for these test sites:
```bash
https://defo.ie/ech-check.php
https://draft-13.esni.defo.ie:8413/stats
https://draft-13.esni.defo.ie:8414/stats
https://crypto.cloudflare.com/cdn-cgi/trace
https://tls-ech.dev
```
The list above has 4 different server technologies, implemented by 3 different
parties, and includes a case (the port 8414 server) where HelloRetryRequest
(HRR) is forced.
We currently support the following new curl command line arguments/options:
- ``--ech <config>`` - the ``config`` value can be one of:
- ``false`` says to not attempt ECH
- ``true`` says to attempt ECH, if possible
- ``grease`` if attempting ECH is not possible, then send a GREASE ECH extension
- ``hard`` hard-fail the connection if ECH cannot be attempted
- ``ecl:<b64value>`` a base64 encoded ECHConfigList, rather than one accessed from the DNS
- ``pn:<name>`` override the ``public_name`` from an ECHConfigList
Note that in the above "attempt ECH" means the client emitting a TLS
ClientHello with a "real" ECH extension, but that does not mean that the
relevant server can succeed in decrypting, as things can fail for other
reasons.
## Supplying an ECHConfigList on the command line
To supply the ECHConfigList on the command line, you might need a bit of
cut-and-paste, e.g.:
```bash
dig +short https defo.ie
1 . ipv4hint=213.108.108.101 ech=AED+DQA8PAAgACD8WhlS7VwEt5bf3lekhHvXrQBGDrZh03n/LsNtAodbUAAEAAEAAQANY292ZXIuZGVmby5pZQAA ipv6hint=2a00:c6c0:0:116:5::10
```
Then paste the base64 encoded ECHConfigList onto the curl command line:
```bash
LD_LIBRARY_PATH=$HOME/code/openssl ./src/curl --ech ecl:AED+DQA8PAAgACD8WhlS7VwEt5bf3lekhHvXrQBGDrZh03n/LsNtAodbUAAEAAEAAQANY292ZXIuZGVmby5pZQAA https://defo.ie/ech-check.php
...
SSL_ECH_STATUS: success <img src="greentick-small.png" alt="good" /> <br/>
...
```
The output snippet above is within the HTML for the webpage.
If you paste in the wrong ECHConfigList (it changes hourly for ``defo.ie``) you
should get an error like this:
```bash
LD_LIBRARY_PATH=$HOME/code/openssl ./src/curl -vvv --ech ecl:AED+DQA8yAAgACDRMQo+qYNsNRNj+vfuQfFIkrrUFmM4vogucxKj/4nzYgAEAAEAAQANY292ZXIuZGVmby5pZQAA https://defo.ie/ech-check.php
...
* OpenSSL/3.3.0: error:0A00054B:SSL routines::ech required
...
```
There is a reason to want this command line option - for use before publishing
an ECHConfigList in the DNS as per the Internet-draft [A well-known URI for
publishing ECHConfigList values](https://datatracker.ietf.org/doc/draft-ietf-tls-wkech/).
If you do use a wrong ECHConfigList value, then the server might return a
good value, via the ``retry_configs`` mechanism. You can see that value in
the verbose output, e.g.:
```bash
LD_LIBRARY_PATH=$HOME/code/openssl ./src/curl -vvv --ech ecl:AED+DQA8yAAgACDRMQo+qYNsNRNj+vfuQfFIkrrUFmM4vogucxKj/4nzYgAEAAEAAQANY292ZXIuZGVmby5pZQAA https://defo.ie/ech-check.php
...
* ECH: retry_configs AQD+DQA8DAAgACBvYqJy+Hgk33wh/ZLBzKSPgwxeop7gvojQzfASq7zeZQAEAAEAAQANY292ZXIuZGVmby5pZQAA/g0APEMAIAAgXkT5r4cYs8z19q5rdittyIX8gfQ3ENW4wj1fVoiJZBoABAABAAEADWNvdmVyLmRlZm8uaWUAAP4NADw2ACAAINXSE9EdXzEQIJZA7vpwCIQsWqsFohZARXChgPsnfI1kAAQAAQABAA1jb3Zlci5kZWZvLmllAAD+DQA8cQAgACASeiD5F+UoSnVoHvA2l1EifUVMFtbVZ76xwDqmMPraHQAEAAEAAQANY292ZXIuZGVmby5pZQAA
* ECH: retry_configs for defo.ie from cover.defo.ie, 319
...
```
At that point, you could copy the base64 encoded value above and try again.
For now, this only works for the OpenSSL and BoringSSL/AWS-LC builds.
## Default settings
curl has various ways to configure default settings, e.g. in ``$HOME/.curlrc``,
so one can set the DoH URL and enable ECH that way:
```bash
cat ~/.curlrc
doh-url=https://one.one.one.one/dns-query
silent
ech=true
```
Note that when you use the system's curl command (rather than our ECH-enabled
build), it is liable to warn that ``ech`` is an unknown option. If that is an
issue (e.g. if some script re-directs stdout and stderr somewhere) then adding
the ``silent`` line above seems to be a good enough fix. (Though of
course, yet another script could depend on non-silent behavior, so you may have
to figure out what you prefer yourself.) That seems to have changed with the
latest build, previously ``silent=TRUE`` was what I used in ``~/.curlrc`` but
now that seems to cause a problem, so that the following line(s) are ignored.
If you want to always use our OpenSSL build you can set ``LD_LIBRARY_PATH``
in the environment:
```bash
export LD_LIBRARY_PATH=$HOME/code/openssl
```
When you do the above, there can be a mismatch between OpenSSL versions
for applications that check that. A ``git push`` for example fails so you
should unset ``LD_LIBRARY_PATH`` before doing that or use a different shell.
```bash
git push
OpenSSL version mismatch. Built against 30000080, you have 30200000
...
```
With all that setup as above the command line gets simpler:
```bash
./src/curl https://defo.ie/ech-check.php
...
SSL_ECH_STATUS: success <img src="greentick-small.png" alt="good" /> <br/>
...
```
The ``--ech true`` option is opportunistic, so tries to do ECH but does not fail if
the client for example cannot find any ECHConfig values. The ``--ech hard``
option hard-fails if there is no ECHConfig found in DNS, so for now, that is not
a good option to set as a default. Once ECH has really been attempted by
the client, if decryption on the server side fails, then curl fails.
## Code changes for ECH support when using DoH
Code changes are ``#ifdef`` protected via ``USE_ECH`` or ``USE_HTTPSRR``:
- ``USE_HTTPSRR`` is used for HTTPS RR retrieval code that could be generically
used should non-ECH uses for HTTPS RRs be identified, e.g. use of ALPN values
or IP address hints.
- ``USE_ECH`` protects ECH specific code.
There are various obvious code blocks for handling the new command line
arguments which are not described here, but should be fairly clear.
As shown in the ``configure`` usage above, there are ``configure.ac`` changes
that allow separately dis/enabling ``USE_HTTPSRR`` and ``USE_ECH``. If ``USE_ECH``
is enabled, then ``USE_HTTPSRR`` is forced. In both cases ``CURL_DISABLE_DOH``
must not be enabled. (There may be some configuration conflicts available for the
determined :-)
The main functional change, as you would expect, is in ``lib/vtls/openssl.c``
where an ECHConfig, if available from command line or DNS cache, is fed into
the OpenSSL library via the new APIs implemented in our OpenSSL fork for that
purpose. This code also implements the opportunistic (``--ech true``) or hard-fail
(``--ech hard``) logic.
Other than that, the main additions are in ``lib/doh.c``
where we reuse ``dohprobe()`` to retrieve an HTTPS RR value for the target
domain. If such a value is found, that is stored using a new ``doh_store_https()``
function in a new field in the ``dohentry`` structure.
The qname for the DoH query is modified if the port number is not 443, as
defined in the SVCB specification.
When the DoH process has worked, ``Curl_doh_is_resolved()`` now also returns
the relevant HTTPS RR value data in the ``Curl_dns_entry`` structure.
That is later accessed when the TLS session is being established, if ECH is
enabled (from ``lib/vtls/openssl.c`` as described above).
## Limitations
Things that need fixing, but that can probably be ignored for the
moment:
- We could easily add code to make use of an ``alpn=`` value found in an HTTPS
RR, passing that on to OpenSSL for use as the "inner" ALPN value, but have
yet to do that.
Current limitations (more interesting than the above):
- Only the first HTTPS RR value retrieved is actually processed as described
above, that could be extended in future, though picking the "right" HTTPS RR
could be non-trivial if multiple RRs are published - matching IP address hints
versus A/AAAA values might be a good basis for that. Last I checked though,
browsers supporting ECH did not handle multiple HTTPS RRs well, though that
needs re-checking as it has been a while.
- It is unclear how one should handle any IP address hints found in an HTTPS RR.
It may be that a bit of consideration of how "multi-CDN" deployments might
emerge would provide good answers there, but for now, it is not clear how best
curl might handle those values when present in the DNS.
- The SVCB/HTTPS RR specification supports a new "CNAME at apex" indirection
("aliasMode") - the current code takes no account of that at all. One could
envisage implementing the equivalent of following CNAMEs in such cases, but
it is not clear if that'd be a good plan. (As of now, chrome browsers do not seem
to have any support for that "aliasMode" and we have not checked Firefox for that
recently.)
- We have not investigated what related changes or additions might be needed
for applications using libcurl, as opposed to use of curl as a command line
tool.
- We have not yet implemented tests as part of the usual curl test harness as
doing so would seem to require re-implementing an ECH-enabled server as part
of the curl test harness. For now, we have a ``./tests/ech_test.sh`` script
that attempts ECH with various test servers and with many combinations of the
allowed command line options. While that is a useful test and has find issues,
it is not comprehensive and we are not (as yet) sure what would be the right
level of coverage. When running that script you should not have a
``$HOME/.curlrc`` file that affects ECH or some of the negative tests could
produce spurious failures.
## Building with cmake
To build with cmake, assuming our ECH-enabled OpenSSL is as before:
```bash
cd $HOME/code
git clone https://github.com/curl/curl
cd curl
mkdir build
cd build
cmake -DOPENSSL_ROOT_DIR=$HOME/code/openssl -DUSE_ECH=1 ..
...
make
...
[100%] Built target curl
```
The binary produced by the cmake build does not need any ECH-specific
``LD_LIBRARY_PATH`` setting.
## BoringSSL build
BoringSSL is also supported by curl and also supports ECH, so to build
with that, instead of our ECH-enabled OpenSSL:
```bash
cd $HOME/code
git clone https://boringssl.googlesource.com/boringssl
cd boringssl
cmake -DCMAKE_INSTALL_PREFIX:PATH=$HOME/code/boringssl/inst -DBUILD_SHARED_LIBS=1
make
...
make install
```
Then:
```bash
cd $HOME/code
git clone https://github.com/curl/curl
cd curl
autoreconf -fi
LDFLAGS="-Wl,-rpath,$HOME/code/boringssl/inst/lib" ./configure --with-ssl=$HOME/code/boringssl/inst --enable-ech
...lots of output...
WARNING: ECH HTTPSRR enabled but marked EXPERIMENTAL. Use with caution.
make
```
The BoringSSL/AWS-LC APIs are fairly similar to those in our ECH-enabled
OpenSSL fork, so code changes are also in ``lib/vtls/openssl.c``, protected
via ``#ifdef OPENSSL_IS_BORINGSSL`` and are mostly obvious API variations.
The BoringSSL/AWS-LC APIs however do not support the ``--ech pn:`` command
line variant as of now.
## wolfSSL build
wolfSSL also supports ECH and can be used by curl, so here's how:
```bash
cd $HOME/code
git clone https://github.com/wolfSSL/wolfssl
cd wolfssl
./autogen.sh
./configure --prefix=$HOME/code/wolfssl/inst --enable-ech --enable-debug --enable-opensslextra
make
make install
```
The install prefix (``inst``) in the above causes wolfSSL to be installed there
and we seem to need that for the curl configure command to work out. The
``--enable-opensslextra`` turns out (after much faffing about;-) to be
important or else we get build problems with curl below.
```bash
cd $HOME/code
git clone https://github.com/curl/curl
cd curl
autoreconf -fi
./configure --with-wolfssl=$HOME/code/wolfssl/inst --enable-ech
make
```
There are some known issues with the ECH implementation in wolfSSL:
- The main issue is that the client currently handles HelloRetryRequest
incorrectly. [HRR issue](https://github.com/wolfSSL/wolfssl/issues/6802).)
The HRR issue means that the client does not work for
[this ECH test web site](https://tls-ech.dev) and any other similarly configured
sites.
- There is also an issue related to so-called middlebox compatibility mode.
[middlebox compatibility issue](https://github.com/wolfSSL/wolfssl/issues/6774)
### Code changes to support wolfSSL
There are what seem like oddball differences:
- The DoH URL in``$HOME/.curlrc`` can use `1.1.1.1` for OpenSSL but has to be
`one.one.one.one` for wolfSSL. The latter works for both, so OK, we us that.
- There seems to be some difference in CA databases too - the wolfSSL version
does not like ``defo.ie``, whereas the system and OpenSSL ones do. We can
ignore that for our purposes via ``--insecure``/``-k`` but would need to fix
for a real setup. (Browsers do like those certificates though.)
Then there are some functional code changes:
- tweak to ``configure.ac`` to check if wolfSSL has ECH or not
- added code to ``lib/vtls/wolfssl.c`` mirroring what's done in the
OpenSSL equivalent above.
- wolfSSL does not support ``--ech false`` or the ``--ech pn:`` command line
argument.
The lack of support for ``--ech false`` is because wolfSSL has decided to
always at least GREASE if built to support ECH. In other words, GREASE is
a compile time choice for wolfSSL, but a runtime choice for OpenSSL or
BoringSSL/AWS-LC. (Both are reasonable.)
## Additional notes
### Supporting ECH without DoH
All of the above only applies if DoH is being used. There should be a use-case
for ECH when DoH is not used by curl - if a system stub resolver supports DoT
or DoH, then, considering only ECH and the network threat model, it would make
sense for curl to support ECH without curl itself using DoH. The author for
example uses a combination of stubby+unbound as the system resolver listening
on localhost:53, so would fit this use-case. That said, it is unclear if
this is a niche that is worth trying to address. (The author is just as happy to
let curl use DoH to talk to the same public recursive that stubby might use:-)
Assuming for the moment this is a use-case we would like to support, then if
DoH is not being used by curl, it is not clear at this time how to provide
support for ECH. One option would seem to be to extend the ``c-ares`` library
to support HTTPS RRs, but in that case it is not now clear whether such
changes would be attractive to the ``c-ares`` maintainers, nor whether the
"tag=value" extensibility inherent in the HTTPS/SVCB specification is a good
match for the ``c-ares`` approach of defining structures specific to decoded
answers for each supported RRtype. We are also not sure how many downstream
curl deployments actually make use of the ``c-ares`` library, which would
affect the utility of such changes. Another option might be to consider using
some other generic DNS library that does support HTTPS RRs, but it is unclear
if such a library could or would be used by all or almost all curl builds and
downstream releases of curl.
Our current conclusion is that doing the above is likely best left until we
have some experience with the "using DoH" approach, so we are going to punt on
this for now.
### Debugging
Just a note to self as remembering this is a nuisance:
```bash
LD_LIBRARY_PATH=$HOME/code/openssl:./lib/.libs gdb ./src/.libs/curl
```
### Localhost testing
It can be useful to be able to run against a localhost OpenSSL ``s_server``
for testing. We have published instructions for such
[localhost tests](https://github.com/defo-project/ech-dev-utils/blob/main/howtos/localhost-tests.md)
in another repository. Once you have that set up, you can start a server
and then run curl against that:
```bash
cd $HOME/code/ech-dev-utils
./scripts/echsvr.sh -d
...
```
The ``echsvr.sh`` script supports many ECH-related options. Use ``echsvr.sh -h``
for details.
In another window:
```bash
cd $HOME/code/curl/
./src/curl -vvv --insecure --connect-to foo.example.com:8443:localhost:8443 --ech ecl:AD7+DQA6uwAgACBix2B78sX+EQhEbxMspDOc8Z3xVS5aQpYP0Cxpc2AWPAAEAAEAAQALZXhhbXBsZS5jb20AAA==
```
### Automated use of ``retry_configs`` not supported so far...
As of now we have not added support for using ``retry_config`` handling in the
application - for a command line tool, one can just use ``dig`` (or ``kdig``)
to get the HTTPS RR and pass the ECHConfigList from that on the command line,
if needed, or one can access the value from command line output in verbose more
and then reuse that in another invocation.
Both our OpenSSL fork and BoringSSL/AWS-LC have APIs for both controlling GREASE
and accessing and logging ``retry_configs``, it seems wolfSSL has neither.
### Testing ECH
We have yet to add a robust test setup for ECH as that requires an ECH-enabled
test server.
We have added two basic tests though, aiming to ensure that the client sends a
GREASE or real ECH extension when requested, and reacts correctly to the
failure of ECH in the latter case. (Given that `stunnel` has no ECH support.)
As with other similar tests, those tests require the `stunnel` tool be
installed. On Ubuntu `sudo apt install stunnel4` achieves that.
The test cases are:
- data/test4000: GREASE ECH, expected result: connection succeeds
- data/test4001: real ECH, connection fails with error 101 (ECH required)

# Experimental
Some features and functionality in curl and libcurl are considered
**EXPERIMENTAL**.
Experimental support in curl means:
1. Experimental features are provided to allow users to try them out and
provide feedback on functionality and API etc before they ship and get
"carved in stone".
2. You must enable the feature when invoking configure as otherwise curl is
not built with the feature present.
3. We strongly advise against using this feature in production.
4. **We reserve the right to change behavior** of the feature without sticking
to our API/ABI rules as we do for regular features, as long as it is marked
experimental.
5. Experimental features are clearly marked so in documentation. Beware.
## Graduation
1. Each experimental feature should have a set of documented requirements of
what is needed for that feature to graduate. Graduation means being removed
from the list of experiments.
2. An experiment should NOT graduate if it needs test cases to be disabled,
unless they are for minor features that are clearly documented as not
provided by the experiment and then the disabling should be managed inside
each affected test case.
## Experimental features right now
### HTTP/3 support (non-ngtcp2 backends)
Graduation requirements:
- The used libraries should be considered out-of-beta with a reasonable
expectation of a stable API going forward.
- Using HTTP/3 with the given build should perform without risking busy-loops
### The Rustls backend
Graduation requirements:
- a reasonable expectation of a stable API going forward.
## ECH
Use of the HTTPS resource record and Encrypted Client Hello (ECH) when using
DoH
Graduation requirements:
- ECH support exists in at least one widely used TLS library apart from
BoringSSL and wolfSSL.
- feedback from users saying that ECH works for their use cases
- it has been given time to mature, so no earlier than April 2025 (twelve
months after being added here)
## SSL session import/export
Import/Export of SSL sessions tickets in libcurl and curl command line
option '--ssl-session <filename>' for faster TLS handshakes and use
of TLSv1.3/QUIC Early Data (0-RTT).
Graduation requirements:
- the implementation is considered safe
- feedback from users saying that session export works for their use cases
## HTTPS RR
HTTPS records support is a requirement for ECH but is provided as a
stand-alone feature that is itself considered EXPERIMENTAL.
Graduation requirements:
- HTTPS records work for DoH, c-ares and the threaded resolver
- HTTPS records can control ALPN and port number, at least
- There are options to control HTTPS use

# Decision making in the curl project
A rough guide to how we make decisions and who does what.
## BDFL
This project was started by and has to some extent been pushed forward over
the years with Daniel Stenberg as the driving force. It matches a standard
BDFL (Benevolent Dictator For Life) style project.
This setup has been used due to convenience and the fact that it has worked
fine this far. It is not because someone thinks of it as a superior project
leadership model. It also only works as long as Daniel manages to listen in to
what the project and the general user population wants and expects from us.
## Legal entity
There is no legal entity. The curl project is just a bunch of people scattered
around the globe with the common goal to produce source code that creates
great products. We are not part of any umbrella organization and we are not
located in any specific country. We are totally independent.
The copyrights in the project are owned by the individuals and organizations
that wrote those parts of the code.
## Decisions
The curl project is not a democracy, but everyone is entitled to state their
opinion and may argue for their sake within the community.
All and any changes that have been done or are done are eligible to bring up
for discussion, to object to or to praise. Ideally, we find consensus for the
appropriate way forward in any given situation or challenge.
If there is no obvious consensus, a maintainer who's knowledgeable in the
specific area takes an "executive" decision that they think is the right for
the project.
## Donations
Donating plain money to curl is best done to curl's [Open Collective
fund](https://opencollective.com/curl). Open Collective is a US based
non-profit organization that holds on to funds for us. This fund is then used
for paying the curl security bug bounties, to reimburse project related
expenses etc.
Donations to the project can also come in the form of server hosting, providing
services and paying for people to work on curl related code etc. Usually, such
donations are services paid for directly by the sponsors.
We grade sponsors in a few different levels and if they meet the criteria,
they can be mentioned on the Sponsors page on the curl website.
## Commercial Support
The curl project does not do or offer commercial support. It only hosts
mailing lists, runs bug trackers etc to facilitate communication and work.
However, Daniel works for wolfSSL and we offer commercial curl support there.
# Key roles
## User
Someone who uses or has used curl or libcurl.
## Contributor
Someone who has helped the curl project, who has contributed to bring it
forward. Contributing could be to provide advice, debug a problem, file a bug
report, run test infrastructure or writing code etc.
## Commit author
Sometimes also called 'committer'. Someone who has authored a commit in the
curl source code repository. Committers are recorded as `Author` in git.
## Maintainers
A maintainer in the curl project is an individual who has been given
permissions to push commits to one of the git repositories.
Maintainers are free to push commits to the repositories at they see fit.
Maintainers are however expected to listen to feedback from users and any
change that is non-trivial in size or nature *should* be brought to the
project as a Pull-Request (PR) to allow others to comment/object before merge.
## Former maintainers
A maintainer who stops being active in the project gets their push permissions
removed at some point. We do this for security reasons but also to make sure
that we always have the list of maintainers as "the team that push stuff to
curl".
Getting push permissions removed is not a punishment. Everyone who ever worked
on maintaining curl is considered a hero, for all time hereafter.
## Security team members
We have a security team. That is the team of people who are subscribed to the
curl-security mailing list; the receivers of security reports from users and
developers. This list of people varies over time but they are all skilled
developers familiar with the curl project.
The security team works best when it consists of a small set of active
persons. We invite new members when the team seems to need it, and we also
expect to retire security team members as they "drift off" from the project or
just find themselves unable to perform their duties there.
## Core team
There is a curl core team. It currently has the same set of members as the
security team. It can also be reached on the security email address.
The core team nominates and invites new members to the team when it sees fit.
There is no open member voting or formal ways to be a candidate. Active
participants in the curl project who want to join the core team can ask to
join.
The core team is a board of advisors. It deals with project management
subjects that need confidentiality or for other reasons cannot be dealt with
and discussed in the open (for example reports of code of conduct violations).
Project matters should always as far as possible be discussed on open mailing
lists.
## Server admins
We run a web server, a mailing list and more on the curl project's primary
server. That physical machine is owned and run by Haxx. Daniel is the primary
admin of all things curl related server stuff, but Björn Stenberg and Linus
Feltzing serve as backup admins for when Daniel is gone or unable.
The primary server is paid for by Haxx. The machine is physically located in a
server bunker in Stockholm Sweden, operated by the company Glesys.
The website contents are served to the web via Fastly and Daniel is the
primary curl contact with Fastly.
## BDFL
That is Daniel.
# Maintainers
A curl maintainer is a project volunteer who has the authority and rights to
merge changes into a git repository in the curl project.
Anyone can aspire to become a curl maintainer.
### Duties
There are no mandatory duties. We hope and wish that maintainers consider
reviewing patches and help merging them, especially when the changes are
within the area of personal expertise and experience.
### Requirements
- only merge code that meets our quality and style guide requirements.
- *never* merge code without doing a PR first, unless the change is "trivial"
- if in doubt, ask for input/feedback from others
### Recommendations
- we require two-factor authentication enabled on your GitHub account to
reduce risk of malicious source code tampering
- consider enabling signed git commits for additional verification of changes
### Merge advice
When you are merging patches/pull requests...
- make sure the commit messages follow our template
- squash patch sets into a few logical commits even if the PR did not, if
necessary
- avoid the "merge" button on GitHub, do it "manually" instead to get full
control and full audit trail (GitHub leaves out you as "Committer:")
- remember to credit the reporter and the helpers.
## Who are maintainers?
The [list of maintainers](https://github.com/orgs/curl/people). Be aware that
the level of presence and activity in the project vary greatly between
different individuals and over time.
### Become a maintainer?
If you think you can help making the project better by shouldering some
maintaining responsibilities, then please get in touch.
You are expected to be familiar with the curl project and its ways of working.
You need to have gotten a few quality patches merged as a proof of this.
### Stop being a maintainer
If you (appear to) not be active in the project anymore, you may be removed as
a maintainer. Thank you for your service.

# How to get started helping out in the curl project
We are always in need of more help. If you are new to the project and are
looking for ways to contribute and help out, this document aims to give a few
good starting points.
You may subscribe to the [curl-library mailing
list](https://lists.haxx.se/listinfo/curl-library) to keep track of the
current discussion topics; or if you are registered on GitHub, you can use the
[Discussions section](https://github.com/curl/curl/discussions) on the main
curl repository.
## Scratch your own itch
One of the best ways is to start working on any problems or issues you have
found yourself or perhaps got annoyed at in the past. It can be a spelling
error in an error text or a weirdly phrased section in a man page. Hunt it
down and report the bug. Or make your first pull request with a fix for that.
## Smaller tasks
Some projects mark small issues as "beginner friendly", "bite-sized" or
similar. We do not do that in curl since such issues never linger around long
enough. Simple issues get handled fast.
If you are looking for a smaller or simpler task in the project to help out
with as an entry-point into the project, perhaps because you are a newcomer or
even maybe not a terribly experienced developer, here's our advice:
- Read through this document to get a grasp on a general approach to use
- Consider adding a test case for something not currently tested (correctly)
- Consider updating or adding documentation
- One way to get started gently in the project, is to participate in an
existing issue/PR and help out by reproducing the issue, review the code in
the PR etc.
## Help wanted
In the issue tracker we occasionally mark bugs with [help
wanted](https://github.com/curl/curl/labels/help%20wanted), as a sign that the
bug is acknowledged to exist and that there is nobody known to work on this
issue for the moment. Those are bugs that are fine to "grab" and provide a
pull request for. The complexity level of these of course varies, so pick one
that piques your interest.
## Work on known bugs
Some bugs are known and have not yet received attention and work enough to get
fixed. We collect such known existing flaws in the
[KNOWN_BUGS](https://curl.se/docs/knownbugs.html) page. Many of them link
to the original bug report with some additional details, but some may also
have aged a bit and may require some verification that the bug still exists in
the same way and that what was said about it in the past is still valid.
## Fix autobuild problems
On the [autobuilds page](https://curl.se/dev/builds.html) we show a
collection of test results from the automatic curl build and tests that are
performed by volunteers. Fixing compiler warnings and errors shown there is
something we value greatly. Also, if you own or run systems or architectures
that are not already tested in the autobuilds, we also appreciate more
volunteers running builds automatically to help us keep curl portable.
## TODO items
Ideas for features and functions that we have considered worthwhile to
implement and provide are kept in the
[TODO](https://curl.se/docs/todo.html) file. Some of the ideas are
rough. Some are well thought out. Some probably are not really suitable
anymore.
Before you invest a lot of time on a TODO item, do bring it up for discussion
on the mailing list. For discussion on applicability but also for ideas and
brainstorming on specific ways to do the implementation etc.
## You decide
You can also come up with a completely new thing you think we should do. Or
not do. Or fix. Or add to the project. You then either bring it to the mailing
list first to see if people shoot down the idea at once, or you bring a first
draft of the idea as a pull request and take the discussion there around the
specific implementation. Either way is fine.
## CONTRIBUTE
We offer [guidelines](https://curl.se/dev/contribute.html) that are suitable
to be familiar with before you decide to contribute to curl. If you are used
to open source development, you probably do not find many surprises there.

How curl Became Like This
=========================
Towards the end of 1996, Daniel Stenberg was spending time writing an IRC bot
for an Amiga related channel on EFnet. He then came up with the idea to make
currency-exchange calculations available to Internet Relay Chat (IRC)
users. All the necessary data were published on the Web; he just needed to
automate their retrieval.
1996
----
On November 11, 1996 the Brazilian developer Rafael Sagula wrote and released
HttpGet version 0.1.
Daniel extended this existing command-line open-source tool. After a few minor
adjustments, it did just what he needed. The first release with Daniel's
additions was 0.2, released on December 17, 1996. Daniel quickly became the
new maintainer of the project.
1997
----
HttpGet 0.3 was released in January 1997 and now it accepted HTTP URLs on the
command line.
HttpGet 1.0 was released on April 8 1997 with brand new HTTP proxy support.
We soon found and fixed support for getting currencies over GOPHER. Once FTP
download support was added, the name of the project was changed and urlget 2.0
was released in August 1997. The http-only days were already passed.
Version 2.2 was released on August 14 1997 and introduced support to build for
and run on Windows and Solaris.
November 24 1997: Version 3.1 added FTP upload support.
Version 3.5 added support for HTTP POST.
1998
----
February 4: urlget 3.10
February 9: urlget 3.11
March 14: urlget 3.12 added proxy authentication.
The project slowly grew bigger. With upload capabilities, the name was once
again misleading and a second name change was made. On March 20, 1998 curl 4
was released. (The version numbering from the previous names was kept.)
(Unrelated to this project a company called Curl Corporation registered a US
trademark on the name "CURL" on May 18 1998. That company had then already
registered the curl.com domain back in November of the previous year. All this
was revealed to us much later.)
SSL support was added, powered by the SSLeay library.
August: first announcement of curl on freshmeat.net.
October: with the curl 4.9 release and the introduction of cookie support,
curl was no longer released under the GPL license. Now we are at 4000 lines of
code, we switched over to the MPL license to restrict the effects of
"copyleft".
November: configure script and reported successful compiles on several
major operating systems. The never-quite-understood -F option was added and
curl could now simulate quite a lot of a browser. TELNET support was added.
curl 5 was released in December 1998 and introduced the first ever curl man
page. People started making Linux RPM packages out of it.
1999
----
January: DICT support added.
OpenSSL took over and SSLeay was abandoned.
May: first Debian package.
August: LDAP:// and FILE:// support added. The curl website gets 1300 visits
weekly. Moved site to curl.haxx.nu.
September: Released curl 6.0. 15000 lines of code.
December 28: added the project on Sourceforge and started using its services
for managing the project.
2000
----
Spring: major internal overhaul to provide a suitable library interface.
The first non-beta release was named 7.1 and arrived in August. This offered
the easy interface and turned out to be the beginning of actually getting
other software and programs to be based on and powered by libcurl. Almost
20000 lines of code.
June: the curl site moves to "curl.haxx.se"
August, the curl website gets 4000 visits weekly.
The PHP guys adopted libcurl already the same month, when the first ever third
party libcurl binding showed up. CURL has been a supported module in PHP since
the release of PHP 4.0.2. This would soon get followers. More than 16
different bindings exist at the time of this writing.
September: kerberos4 support was added.
November: started the work on a test suite for curl. It was later re-written
from scratch again. The libcurl major SONAME number was set to 1.
2001
----
January: Daniel released curl 7.5.2 under a new license again: MIT (or
MPL). The MIT license is extremely liberal and can be combined with GPL
in other projects. This would finally put an end to the "complaints" from
people involved in GPLed projects that previously were prohibited from using
libcurl while it was released under MPL only. (Due to the fact that MPL is
deemed "GPL incompatible".)
March 22: curl supports HTTP 1.1 starting with the release of 7.7. This
also introduced libcurl's ability to do persistent connections. 24000 lines of
code. The libcurl major SONAME number was bumped to 2 due to this overhaul.
The first experimental ftps:// support was added.
August: The curl website gets 8000 visits weekly. Curl Corporation contacted
Daniel to discuss "the name issue". After Daniel's reply, they have never
since got back in touch again.
September: libcurl 7.9 introduces cookie jar and `curl_formadd()`. During the
forthcoming 7.9.x releases, we introduced the multi interface slowly and
without many whistles.
September 25: curl (7.7.2) is bundled in Mac OS X (10.1) for the first time. It was
already becoming more and more of a standard utility of Linux distributions
and a regular in the BSD ports collections.
2002
----
June: the curl website gets 13000 visits weekly. curl and libcurl is
35000 lines of code. Reported successful compiles on more than 40 combinations
of CPUs and operating systems.
To estimate the number of users of the curl tool or libcurl library is next to
impossible. Around 5000 downloaded packages each week from the main site gives
a hint, but the packages are mirrored extensively, bundled with numerous OS
distributions and otherwise retrieved as part of other software.
October 1: with the release of curl 7.10 it is released under the MIT license
only.
Starting with 7.10, curl verifies SSL server certificates by default.
2003
----
January: Started working on the distributed curl tests. The autobuilds.
February: the curl site averages at 20000 visits weekly. At any given moment,
there is an average of 3 people browsing the website.
Multiple new authentication schemes are supported: Digest (May), NTLM (June)
and Negotiate (June).
November: curl 7.10.8 is released. 45000 lines of code. ~55000 unique visitors
to the website. Five official web mirrors.
December: full-fledged SSL for FTP is supported.
2004
----
January: curl 7.11.0 introduced large file support.
June: curl 7.12.0 introduced IDN support. 10 official web mirrors.
This release bumped the major SONAME to 3 due to the removal of the
`curl_formparse()` function

Public curl release number: 82
Releases counted from the beginning: 109
Available command line options: 96
Available curl_easy_setopt() options: 120
Number of public functions in libcurl: 36
Amount of public website mirrors: 12

2005
----
April: GnuTLS can now optionally be used for the secure layer when curl is
built.
April: Added the multi_socket() API
September: TFTP support was added.
More than 100,000 unique visitors of the curl website. 25 mirrors.
December: security vulnerability: libcurl URL Buffer Overflow
2006
----
January: We dropped support for Gopher. We found bugs in the implementation
that turned out to have been introduced years ago, so with the conclusion that
nobody had found out in all this time we removed it instead of fixing it.
March: security vulnerability: libcurl TFTP Packet Buffer Overflow
September: The major SONAME number for libcurl was bumped to 4 due to the
removal of ftp third party transfer support.
November: Added SCP and SFTP support

HTTP Strict-Transport-Security. Added as experimental in curl
7.74.0. Supported "for real" since 7.77.0.
## Standard
[HTTP Strict Transport Security](https://datatracker.ietf.org/doc/html/rfc6797)
## Behavior
libcurl features an in-memory cache for HSTS hosts, so that subsequent
HTTP-only requests to a hostname present in the cache gets internally
"redirected" to the HTTPS version.
## `curl_easy_setopt()` options:
- `CURLOPT_HSTS_CTRL` - enable HSTS for this easy handle
- `CURLOPT_HSTS` - specify filename where to store the HSTS cache on close
(and possibly read from at startup)
## curl command line options
- `--hsts [filename]` - enable HSTS, use the file as HSTS cache. If filename
is `""` (no length) then no file is used, only in-memory cache.
## HSTS cache file format
Lines starting with `#` are ignored.
For each hsts entry:
[host name] "YYYYMMDD HH:MM:SS"
The `[host name]` is dot-prefixed if it includes subdomains.
The time stamp is when the entry expires.
## Possible future additions
- `CURLOPT_HSTS_PRELOAD` - provide a set of HSTS hostnames to load first
- ability to save to something else than a file

# HTTP Cookies
## Cookie overview
Cookies are `name=contents` pairs that an HTTP server tells the client to
hold and then the client sends back those to the server on subsequent
requests to the same domains and paths for which the cookies were set.
Cookies are either "session cookies" which typically are forgotten when the
session is over which is often translated to equal when browser quits, or
the cookies are not session cookies they have expiration dates after which
the client throws them away.
Cookies are set to the client with the Set-Cookie: header and are sent to
servers with the Cookie: header.
For a long time, the only spec explaining how to use cookies was the
original [Netscape spec from 1994](https://curl.se/rfc/cookie_spec.html).
In 2011, [RFC 6265](https://www.ietf.org/rfc/rfc6265.txt) was finally
published and details how cookies work within HTTP. In 2016, an update which
added support for prefixes was
[proposed](https://datatracker.ietf.org/doc/html/draft-ietf-httpbis-cookie-prefixes-00),
and in 2017, another update was
[drafted](https://datatracker.ietf.org/doc/html/draft-ietf-httpbis-cookie-alone-01)
to deprecate modification of 'secure' cookies from non-secure origins. Both
of these drafts have been incorporated into a proposal to
[replace](https://datatracker.ietf.org/doc/html/draft-ietf-httpbis-rfc6265bis-11)
RFC 6265. Cookie prefixes and secure cookie modification protection has been
implemented by curl.
curl considers `http://localhost` to be a *secure context*, meaning that it
allows and uses cookies marked with the `secure` keyword even when done over
plain HTTP for this host. curl does this to match how popular browsers work
with secure cookies.
## Super cookies
A single cookie can be set for a domain that matches multiple hosts. Like if
set for `example.com` it gets sent to both `aa.example.com` as well as
`bb.example.com`.
A challenge with this concept is that there are certain domains for which
cookies should not be allowed at all, because they are *Public
Suffixes*. Similarly, a client never accepts cookies set directly for the
top-level domain like for example `.com`. Cookies set for *too broad*
domains are generally referred to as *super cookies*.
If curl is built with PSL (**Public Suffix List**) support, it detects and
discards cookies that are specified for such suffix domains that should not
be allowed to have cookies.
if curl is *not* built with PSL support, it has no ability to stop super
cookies.
## Cookies saved to disk
Netscape once created a file format for storing cookies on disk so that they
would survive browser restarts. curl adopted that file format to allow
sharing the cookies with browsers, only to see browsers move away from that
format. Modern browsers no longer use it, while curl still does.
The Netscape cookie file format stores one cookie per physical line in the
file with a bunch of associated meta data, each field separated with
TAB. That file is called the cookie jar in curl terminology.
When libcurl saves a cookie jar, it creates a file header of its own in
which there is a URL mention that links to the web version of this document.
## Cookie file format
The cookie file format is text based and stores one cookie per line. Lines
that start with `#` are treated as comments. An exception is lines that
start with `#HttpOnly_`, which is a prefix for cookies that have the
`HttpOnly` attribute set.
Each line that specifies a single cookie consists of seven text fields
separated with TAB characters. A valid line must end with a newline
character.
### Fields in the file
Field number, what type and example data and the meaning of it:
0. string `example.com` - the domain name
1. boolean `FALSE` - include subdomains
2. string `/foobar/` - path
3. boolean `TRUE` - send/receive over HTTPS only
4. number `1462299217` - expires at - seconds since Jan 1st 1970, or 0
5. string `person` - name of the cookie
6. string `daniel` - value of the cookie
## Cookies with curl the command line tool
curl has a full cookie "engine" built in. If you just activate it, you can
have curl receive and send cookies exactly as mandated in the specs.
Command line options:
[`-b, --cookie`](https://curl.se/docs/manpage.html#-b)
tell curl a file to read cookies from and start the cookie engine, or if it
is not a file it passes on the given string. `-b name=var` works and so does
`-b cookiefile`.
[`-j, --junk-session-cookies`](https://curl.se/docs/manpage.html#-j)
when used in combination with -b, it skips all "session cookies" on load so
as to appear to start a new cookie session.
[`-c, --cookie-jar`](https://curl.se/docs/manpage.html#-c)
tell curl to start the cookie engine and write cookies to the given file
after the request(s)
## Cookies with libcurl
libcurl offers several ways to enable and interface the cookie engine. These
options are the ones provided by the native API. libcurl bindings may offer
access to them using other means.
[`CURLOPT_COOKIE`](https://curl.se/libcurl/c/CURLOPT_COOKIE.html)
Is used when you want to specify the exact contents of a cookie header to
send to the server.
[`CURLOPT_COOKIEFILE`](https://curl.se/libcurl/c/CURLOPT_COOKIEFILE.html)
Tell libcurl to activate the cookie engine, and to read the initial set of
cookies from the given file. Read-only.
[`CURLOPT_COOKIEJAR`](https://curl.se/libcurl/c/CURLOPT_COOKIEJAR.html)
Tell libcurl to activate the cookie engine, and when the easy handle is
closed save all known cookies to the given cookie jar file. Write-only.
[`CURLOPT_COOKIELIST`](https://curl.se/libcurl/c/CURLOPT_COOKIELIST.html)
Provide detailed information about a single cookie to add to the internal
storage of cookies. Pass in the cookie as an HTTP header with all the
details set, or pass in a line from a Netscape cookie file. This option can
also be used to flush the cookies etc.
[`CURLOPT_COOKIESESSION`](https://curl.se/libcurl/c/CURLOPT_COOKIESESSION.html)
Tell libcurl to ignore all cookies it is about to load that are session
cookies.
[`CURLINFO_COOKIELIST`](https://curl.se/libcurl/c/CURLINFO_COOKIELIST.html)
Extract cookie information from the internal cookie storage as a linked
list.
## Cookies with JavaScript
These days a lot of the web is built up by JavaScript. The web browser loads
complete programs that render the page you see. These JavaScript programs
can also set and access cookies.
Since curl and libcurl are plain HTTP clients without any knowledge of or
capability to handle JavaScript, such cookies are not detected or used.
Often, if you want to mimic what a browser does on such websites, you can
record web browser HTTP traffic when using such a site and then repeat the
cookie operations using curl or libcurl.

# HTTP3 (and QUIC)
## Resources
[HTTP/3 Explained](https://http3-explained.haxx.se/en/) - the online free
book describing the protocols involved.
[quicwg.org](https://quicwg.org/) - home of the official protocol drafts
## QUIC libraries
QUIC libraries we are using:
[ngtcp2](https://github.com/ngtcp2/ngtcp2)
[quiche](https://github.com/cloudflare/quiche) - **EXPERIMENTAL**
[OpenSSL 3.2+ QUIC](https://github.com/openssl/openssl) - **EXPERIMENTAL**
[msh3](https://github.com/nibanks/msh3) (with [msquic](https://github.com/microsoft/msquic)) - **EXPERIMENTAL**
## Experimental
HTTP/3 support in curl is considered **EXPERIMENTAL** until further notice
when built to use *quiche* or *msh3*. Only the *ngtcp2* backend is not
experimental.
Further development and tweaking of the HTTP/3 support in curl happens in the
master branch using pull-requests, just like ordinary changes.
To fix before we remove the experimental label:
- the used QUIC library needs to consider itself non-beta
- it is fine to "leave" individual backends as experimental if necessary
# ngtcp2 version
Building curl with ngtcp2 involves 3 components: `ngtcp2` itself, `nghttp3` and a QUIC supporting TLS library. The supported TLS libraries are covered below.
While any version of `ngtcp2` and `nghttp3` from v1.0.0 on are expected to
work, using the latest versions often brings functional and performance
improvements.
The build examples use `$NGHTTP3_VERSION` and `$NGTCP2_VERSION` as placeholders
for the version you build.
## Build with OpenSSL
OpenSSL v3.5.0+ offers APIs for integration with *ngtcp2* v1.12.0+. Earlier
versions do not work.
Build OpenSSL (version 3.5.0 or newer):
% git clone --quiet --depth=1 -b openssl-$OPENSSL_VERSION https://github.com/openssl/openssl
% cd openssl
% ./config --prefix=<somewhere1> --libdir=lib
% make
% make install
Build nghttp3:
% cd ..
% git clone -b $NGHTTP3_VERSION https://github.com/ngtcp2/nghttp3
% cd nghttp3
% git submodule update --init
% autoreconf -fi
% ./configure --prefix=<somewhere2> --enable-lib-only
% make
% make install
Build ngtcp2:
% cd ..
% git clone -b $NGTCP2_VERSION https://github.com/ngtcp2/ngtcp2
% cd ngtcp2
% autoreconf -fi
% ./configure PKG_CONFIG_PATH=<somewhere1>/lib/pkgconfig:<somewhere2>/lib/pkgconfig LDFLAGS="-Wl,-rpath,<somewhere1>/lib" --prefix=<somewhere3> --enable-lib-only --with-openssl
% make
% make install
Build curl:
% cd ..
% git clone https://github.com/curl/curl
% cd curl
% autoreconf -fi
% LDFLAGS="-Wl,-rpath,<somewhere1>/lib" ./configure --with-openssl=<somewhere1> --with-nghttp3=<somewhere2> --with-ngtcp2=<somewhere3>
% make
% make install
## Build with quictls
OpenSSL does not offer the required APIs for building a QUIC client. You need
to use a TLS library that has such APIs and that works with *ngtcp2*.
Build quictls (any `+quic` tagged version works):
% git clone --depth 1 -b openssl-3.1.4+quic https://github.com/quictls/openssl
% cd openssl
% ./config enable-tls1_3 --prefix=<somewhere1> --libdir=lib
% make
% make install
Build nghttp3:
% cd ..
% git clone -b $NGHTTP3_VERSION https://github.com/ngtcp2/nghttp3
% cd nghttp3
% git submodule update --init
% autoreconf -fi
% ./configure --prefix=<somewhere2> --enable-lib-only
% make
% make install
Build ngtcp2:
% cd ..
% git clone -b $NGTCP2_VERSION https://github.com/ngtcp2/ngtcp2
% cd ngtcp2
% autoreconf -fi
% ./configure PKG_CONFIG_PATH=<somewhere1>/lib/pkgconfig:<somewhere2>/lib/pkgconfig LDFLAGS="-Wl,-rpath,<somewhere1>/lib" --prefix=<somewhere3> --enable-lib-only
% make
% make install
Build curl:
% cd ..
% git clone https://github.com/curl/curl
% cd curl
% autoreconf -fi
% LDFLAGS="-Wl,-rpath,<somewhere1>/lib" ./configure --with-openssl=<somewhere1> --with-nghttp3=<somewhere2> --with-ngtcp2=<somewhere3>
% make
% make install
## Build with GnuTLS
Build GnuTLS:
% git clone --depth 1 https://gitlab.com/gnutls/gnutls.git
% cd gnutls
% ./bootstrap
% ./configure --prefix=<somewhere1>
% make
% make install
Build nghttp3:
% cd ..
% git clone -b $NGHTTP3_VERSION https://github.com/ngtcp2/nghttp3
% cd nghttp3
% git submodule update --init
% autoreconf -fi
% ./configure --prefix=<somewhere2> --enable-lib-only
% make
% make install
Build ngtcp2:
% cd ..
% git clone -b $NGTCP2_VERSION https://github.com/ngtcp2/ngtcp2
% cd ngtcp2
% autoreconf -fi
% ./configure PKG_CONFIG_PATH=<somewhere1>/lib/pkgconfig:<somewhere2>/lib/pkgconfig LDFLAGS="-Wl,-rpath,<somewhere1>/lib" --prefix=<somewhere3> --enable-lib-only --with-gnutls
% make
% make install
Build curl:
% cd ..
% git clone https://github.com/curl/curl
% cd curl
% autoreconf -fi
% ./configure --with-gnutls=<somewhere1> --with-nghttp3=<somewhere2> --with-ngtcp2=<somewhere3>
% make
% make install
## Build with wolfSSL
Build wolfSSL:
% git clone https://github.com/wolfSSL/wolfssl.git
% cd wolfssl
% autoreconf -fi
% ./configure --prefix=<somewhere1> --enable-quic --enable-session-ticket --enable-earlydata --enable-psk --enable-harden --enable-altcertchains
% make
% make install
Build nghttp3:
% cd ..
% git clone -b $NGHTTP3_VERSION https://github.com/ngtcp2/nghttp3
% cd nghttp3
% git submodule update --init
% autoreconf -fi
% ./configure --prefix=<somewhere2> --enable-lib-only
% make
% make install
Build ngtcp2:
% cd ..
% git clone -b $NGTCP2_VERSION https://github.com/ngtcp2/ngtcp2
% cd ngtcp2
% autoreconf -fi
% ./configure PKG_CONFIG_PATH=<somewhere1>/lib/pkgconfig:<somewhere2>/lib/pkgconfig LDFLAGS="-Wl,-rpath,<somewhere1>/lib" --prefix=<somewhere3> --enable-lib-only --with-wolfssl
% make
% make install
Build curl:
% cd ..
% git clone https://github.com/curl/curl
% cd curl
% autoreconf -fi
% ./configure --with-wolfssl=<somewhere1> --with-nghttp3=<somewhere2> --with-ngtcp2=<somewhere3>

# quiche version
quiche support is **EXPERIMENTAL**
Since the quiche build manages its dependencies, curl can be built against the latest version. You are *probably* able to build against their main branch, but in case of problems, we recommend their latest release tag.
## Build
Build quiche and BoringSSL:
% git clone --recursive -b 0.22.0 https://github.com/cloudflare/quiche
% cd quiche
% cargo build --package quiche --release --features ffi,pkg-config-meta,qlog
% ln -s libquiche.so target/release/libquiche.so.0
% mkdir quiche/deps/boringssl/src/lib
% ln -vnf $(find target/release -name libcrypto.a -o -name libssl.a) quiche/deps/boringssl/src/lib/
Build curl:
% cd ..
% git clone https://github.com/curl/curl
% cd curl
% autoreconf -fi
% ./configure LDFLAGS="-Wl,-rpath,$PWD/../quiche/target/release" --with-openssl=$PWD/../quiche/quiche/deps/boringssl/src --with-quiche=$PWD/../quiche/target/release
% make
% make install
If `make install` results in `Permission denied` error, you need to prepend
it with `sudo`.
# OpenSSL version
QUIC support is **EXPERIMENTAL**
Use OpenSSL 3.3.1 or newer (QUIC support was added in 3.3.0, with
shortcomings on some platforms like macOS). 3.4.1 or newer is recommended.
Build via:
% cd ..
% git clone -b $OPENSSL_VERSION https://github.com/openssl/openssl
% cd openssl
% ./config enable-tls1_3 --prefix=<somewhere> --libdir=lib
% make
% make install
Build nghttp3:
% cd ..
% git clone -b $NGHTTP3_VERSION https://github.com/ngtcp2/nghttp3
% cd nghttp3
% git submodule update --init
% autoreconf -fi
% ./configure --prefix=<somewhere2> --enable-lib-only
% make
% make install
Build curl:
% cd ..
% git clone https://github.com/curl/curl
% cd curl
% autoreconf -fi
% LDFLAGS="-Wl,-rpath,<somewhere>/lib" ./configure --with-openssl=<somewhere> --with-openssl-quic --with-nghttp3=<somewhere2>
% make
% make install
You can build curl with cmake:
% cd ..
% git clone https://github.com/curl/curl
% cd curl
% cmake -B bld -DCURL_USE_OPENSSL=ON -DUSE_OPENSSL_QUIC=ON
% cmake --build bld
% cmake --install bld
If `make install` results in `Permission denied` error, you need to prepend
it with `sudo`.
# msh3 (msquic) version
**Note**: The msquic HTTP/3 backend is immature and is not properly functional
one as of September 2023. Feel free to help us test it and improve it, but
there is no point in filing bugs about it just yet.
msh3 support is **EXPERIMENTAL**
## Build Linux (with quictls fork of OpenSSL)
Build msh3:
% git clone -b v0.6.0 --depth 1 --recursive https://github.com/nibanks/msh3
% cd msh3 && mkdir build && cd build
% cmake -G 'Unix Makefiles' -DCMAKE_BUILD_TYPE=RelWithDebInfo ..
% cmake --build .
% cmake --install .
Build curl:
% git clone https://github.com/curl/curl
% cd curl
% autoreconf -fi
% ./configure LDFLAGS="-Wl,-rpath,/usr/local/lib" --with-msh3=/usr/local --with-openssl
% make
% make install
Run from `/usr/local/bin/curl`.
## Build Windows
Build msh3:
% git clone -b v0.6.0 --depth 1 --recursive https://github.com/nibanks/msh3
% cd msh3 && mkdir build && cd build
% cmake -G 'Visual Studio 17 2022' -DCMAKE_BUILD_TYPE=RelWithDebInfo ..
% cmake --build . --config Release
% cmake --install . --config Release
**Note** - On Windows, Schannel is used for TLS support by default. If you
with to use (the quictls fork of) OpenSSL, specify the `-DQUIC_TLS=openssl`
option to the generate command above. Also note that OpenSSL brings with it an
additional set of build dependencies not specified here.
Build curl (in [Visual Studio Command
prompt](../winbuild/README.md#open-a-command-prompt)):
% git clone https://github.com/curl/curl
% cd curl/winbuild
% nmake /f Makefile.vc mode=dll WITH_MSH3=dll MSH3_PATH="C:/Program Files/msh3" MACHINE=x64
Run in the `C:/Program Files/msh3/lib` directory, copy `curl.exe` to that
directory, or copy `msquic.dll` and `msh3.dll` from that directory to the
`curl.exe` directory. For example:
% C:\Program Files\msh3\lib> F:\curl\builds\libcurl-vc-x64-release-dll-ipv6-sspi-schannel-msh3\bin\curl.exe --http3 https://curl.se/
# `--http3`
Use only HTTP/3:
% curl --http3-only https://example.org:4433/
Use HTTP/3 with fallback to HTTP/2 or HTTP/1.1 (see "HTTPS eyeballing" below):
% curl --http3 https://example.org:4433/
Upgrade via Alt-Svc:
% curl --alt-svc altsvc.cache https://curl.se/
See this [list of public HTTP/3 servers](https://bagder.github.io/HTTP3-test/)
### HTTPS eyeballing
With option `--http3` curl attempts earlier HTTP versions as well should the
connect attempt via HTTP/3 not succeed "fast enough". This strategy is similar
to IPv4/6 happy eyeballing where the alternate address family is used in
parallel after a short delay.
The IPv4/6 eyeballing has a default of 200ms and you may override that via
`--happy-eyeballs-timeout-ms value`. Since HTTP/3 is still relatively new, we
decided to use this timeout also for the HTTP eyeballing - with a slight
twist.
The `happy-eyeballs-timeout-ms` value is the **hard** timeout, meaning after
that time expired, a TLS connection is opened in addition to negotiate HTTP/2
or HTTP/1.1. At half of that value - currently - is the **soft** timeout. The
soft timeout fires, when there has been **no data at all** seen from the
server on the HTTP/3 connection.
So, without you specifying anything, the hard timeout is 200ms and the soft is 100ms:
* Ideally, the whole QUIC handshake happens and curl has an HTTP/3 connection
in less than 100ms.
* When QUIC is not supported (or UDP does not work for this network path), no
reply is seen and the HTTP/2 TLS+TCP connection starts 100ms later.
* In the worst case, UDP replies start before 100ms, but drag on. This starts
the TLS+TCP connection after 200ms.
* When the QUIC handshake fails, the TLS+TCP connection is attempted right
away. For example, when the QUIC server presents the wrong certificate.
The whole transfer only fails, when **both** QUIC and TLS+TCP fail to
handshake or time out.
Note that all this happens in addition to IP version happy eyeballing. If the
name resolution for the server gives more than one IP address, curl tries all
those until one succeeds - just as with all other protocols. If those IP
addresses contain both IPv6 and IPv4, those attempts happen, delayed, in
parallel (the actual eyeballing).
## Known Bugs
Check out the [list of known HTTP3 bugs](https://curl.se/docs/knownbugs.html#HTTP3).
# HTTP/3 Test server
This is not advice on how to run anything in production. This is for
development and experimenting.
## Prerequisite(s)
An existing local HTTP/1.1 server that hosts files. Preferably also a few huge
ones. You can easily create huge local files like `truncate -s=8G 8GB` - they
are huge but do not occupy that much space on disk since they are just big
holes.
In a Debian setup you can install apache2. It runs on port 80 and has a
document root in `/var/www/html`. Download the 8GB file from apache with `curl
localhost/8GB -o dev/null`
In this description we setup and run an HTTP/3 reverse-proxy in front of the
HTTP/1 server.
## Setup
You can select either or both of these server solutions.
### nghttpx
Get, build and install quictls, nghttp3 and ngtcp2 as described
above.
Get, build and install nghttp2:
% git clone https://github.com/nghttp2/nghttp2.git
% cd nghttp2
% autoreconf -fi
% PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/home/daniel/build-quictls/lib/pkgconfig:/home/daniel/build-nghttp3/lib/pkgconfig:/home/daniel/build-ngtcp2/lib/pkgconfig LDFLAGS=-L/home/daniel/build-quictls/lib CFLAGS=-I/home/daniel/build-quictls/include ./configure --enable-maintainer-mode --prefix=/home/daniel/build-nghttp2 --disable-shared --enable-app --enable-http3 --without-jemalloc --without-libxml2 --without-systemd
% make && make install
Run the local h3 server on port 9443, make it proxy all traffic through to
HTTP/1 on localhost port 80. For local toying, we can just use the test cert
that exists in curl's test dir.
% CERT=/path/to/stunnel.pem
% $HOME/bin/nghttpx $CERT $CERT --backend=localhost,80 \
--frontend="localhost,9443;quic"
### Caddy
[Install Caddy](https://caddyserver.com/docs/install). For easiest use, the binary
should be either in your PATH or your current directory.
Create a `Caddyfile` with the following content:
~~~
localhost:7443 {
respond "Hello, world! you are using {http.request.proto}"
}
~~~
Then run Caddy:
% ./caddy start
Making requests to `https://localhost:7443` should tell you which protocol is being used.
You can change the hard-coded response to something more useful by replacing `respond`
with `reverse_proxy` or `file_server`, for example: `reverse_proxy localhost:80`

# HTTPS RR
[RFC 9460](https://www.rfc-editor.org/rfc/rfc9460.html) documents the HTTPS
DNS Resource Record.
curl features **experimental** support for HTTPS RR.
- The ALPN list from the record is parsed and used
- The ECH field is stored - and used if ECH is enabled in the build
- The port number is not used (Firefox supports it, Chrome does not)
- The target name is not used
- The IP addresses (`Ipv6hints`, `Ipv4hints`) from the HTTPS RR are not used
- It only supports a single HTTPS RR per hostname
- Hostnames without A/AAAA records but *with* HTTPS RR fails
- consider service profiles where the RR provides different addresses for TCP
vs QUIC etc
`HTTPSRR` is listed as a feature in the `curl -V` output if curl contains
HTTPS RR support. If c-ares is not included in the build, the HTTPS RR support
is limited to DoH.
`asyn-rr` is listed as a feature in the `curl -V` output if c-ares is used for
additional resolves in addition to a "normal" resolve done with the threaded
resolver.
The data extracted from the HTTPS RR is stored in the in-memory DNS cache to
be reused on subsequent uses of the same hostnames.
## limitations
We have decided to work on the HTTPS RR support by following what seems to be
(widely) used, and simply wait with implementing the details of the record
that do not seem to be deployed. HTTPS RR is a DNS field with many odd corners
and complexities and we might as well avoid them if no one seems to want them.
## build
./configure --enable-httpsrr
or
cmake -DUSE_HTTPSRR=ON
## ALPN
The list of ALPN IDs is parsed but may not be completely respected because of
what the HTTP version preference is set to, which is a problem we are working
on. Also, getting an `HTTP/1.1` ALPN in the HTTPS RR field for an HTTP://
transfer should imply switching to HTTPS, HSTS style. Which curl currently
does not.
## DoH
When HTTPS RR is enabled in the curl build, The DoH code asks for an HTTPS
record in addition to the A and AAAA records, and if an HTTPS RR answer is
returned, curl parses it and stores the retrieved information.
## Non-DoH
If DoH is not used for name resolving in an HTTPS RR enabled build, we must
provide the ability using the regular resolver backends. We use the c-ares DNS
library for the HTTPS RR lookup. Version 1.28.0 or later.
### c-ares
If curl is built to use the c-ares library for name resolves, an HTTPS RR
enabled build makes a request for the HTTPS RR in addition to the regular
lookup.
### Threaded resolver
When built to use the threaded resolver, which is the default, an HTTPS RR
build still needs a c-ares installation provided so that a separate request
for the HTTPS record can be done in parallel to the regular getaddrinfo()
call.
This is done by specifying both c-ares and threaded resolver to configure:
./configure --enable-ares=... --enable-threaded-resolver
or to cmake:
cmake -DENABLE_ARES=ON -DENABLE_THREADED_RESOLVER=ON
Because the HTTPS record is handled separately from the A/AAAA record
retrieval, by a separate library, there is a small risk for discrepancies.
When building curl using the threaded resolver with HTTPS RR support (using
c-ares), the `curl -V` output looks exactly like a c-ares resolver build.
## HTTPS RR Options
Because curl is a low level transfer tool for which users sometimes want
detailed control, we need to offer options to control HTTPS RR use.

# Infrastructure in the curl project
Overview of infrastructure we maintain, host and run in the project for the
project.
## git repository
Since 2010, the main curl git repository has been hosted by GitHub, available
at https://github.com/curl/curl.
We also use the issue tracker, pull requests and discussions on GitHub.
curl has an "enterprise account" on GitHub and is an "organization" on the
site.
We accept sponsorship via GitHub Sponsors.
## CI services
For every pull request and git push to the master repository, a number of
build and testing jobs are run on a set of different CI services. The exact
services vary over time. GitHub Actions and AppVeyor are the primary ones
these days.
## Test Clutch
A [Test Clutch](https://github.com/dfandrich/testclutch) instance generates
regular reports on curl CI test results at https://testclutch.curl.se/ as well
as writing comments on curl pull requests whose tests have failed. The jobs
are hosted on a Virtuozzo Application Platform PaaS instance and is managed by
Dan Fandrich. The configuration code is available and managed at
https://github.com/dfandrich/testclutch-curl-web
## Autobuilds
The curl autobuild system is a set of scripts that build and test curl and
send all output logs back to the autobuild server. The results are
continuously collected and visualized on the curl website at
<https://curl.se/dev/builds.html>.
The autobuild system and server is maintained by Daniel Stenberg.
## OSS-Fuzz
Google runs the [OSS-Fuzz](https://google.github.io/oss-fuzz/) project which
also runs fuzzing on curl code, non-stop, in their infrastructure and they
send us emails in the rare instances they actually find something.
OSS-Fuzz notifies those that are members in the "curl team". Any curl
maintainer who wants to is welcome to participate. It requires a Google
account.
## Coverity
We regularly run our code through the [Coverity static code
analyzer](https://scan.coverity.com/) thanks to them offering this service to
us for free.
## CodeSonar
[CodeSonar](https://codesecure.com/our-products/codesonar/) analyzes the curl
source code daily and emails Daniel Stenberg whenever it finds suspected
problems in the source code. I hope and expect that we can invite other
maintainers to access these reports soon.
## Domain names
The project runs services and website using a few different curl related
domain names, including `curl.se` and `curl.dev`. Daniel Stenberg owns these
domain names.
Until a few years ago, the curl website was present at `curl.haxx.se`. The
`haxx.se` domain is owned by Haxx AB, administrated by Daniel Stenberg. The
curl.haxx.se name is meant to keep working and be redirecting to curl.se for
the foreseeable future.
## Websites
The main curl website at `curl.se` is maintained by curl maintainers and the
content is available and managed at https://github.com/curl/curl-www. The site
updates from git and runs make every 20 minutes. Any change pushed to git can
thus take up to 20 minutes until it takes effect on the origin server.
The content on `curl.dev` is available and managed at
https://github.com/curl/curl.dev/
The content on `everything-curl.dev` is available and managed at
https://github.com/curl/everything-curl/
The machine hosting the website contents for these three sites is owned by
Haxx AB and is primarily managed by Daniel Stenberg (co-owner of the Haxx
company). The machine is physically located in Sweden.
curl release tarballs are hosted on https://curl.se/download.html. They are
uploaded there at release-time by the release manager.
curl-for-win downloads are hosted on https://curl.se/windows and are uploaded
to the server by Viktor Szakats.
curl-for-QNX downloads are hosted on <https://curl.se/qnx> and are uploaded to
the server by Daniel Stenberg.
Daily release tarball-like snapshots are generated automatically and are
provided for download at <https://curl.se/snapshots/>.
CA certificate bundles are extracted from the Firefox source code, hosted by
Mozilla and converted to PEM file format and is offered for download. The
conversion checks for updates daily. The bundle is provided for download at
<https://curl.se/docs/caextract.html>.
There is an automated "download check bot" that runs twice daily to scan for
available curl downloads to populate the curl download page appropriately with
the correct updated information. The bot uses URLs and patterns for all
download packages and is maintained in a database, maintained by Daniel
Stenberg and Dan Fandrich.
The TLS certificate for the origin curl web server is automatically updated
from Let's Encrypt.
## CDN
Fastly runs the Content Delivery Network (CDN) that fronts all the curl
websites. The CDN caches content that it gets from the origin server.
Recently, roughly 99.99% of web requests are satisfied by the CDN without
having to reach the origin.
The CDN caches different content at different lengths depending on the
content-type. The caching thus adds to the time for a change to have an effect
on the site from the moment it gets pushed to the git repository.
Using this setup, we provide four IPv4 addresses and eight IPv6 addresses for
anycast access to the site. Should be snappy from virtually everywhere across
the globe.
The CDN servers support HTTP/1, HTTP/2 and HTTP/3. They set HSTS for a year.
The `HTTP://` version of the site redirects to `HTTPS://`.
Fastly manages the TLS certificates from Let's Encrypt for the servers they
run on the behalf of curl.
## Containers
The curl project offer container builds of curl. The source repository for
them is located at <https://github.com/curl/curl-container>.
Container images are hosted at <https://quay.io/repository/curl/curl> and
<https://hub.docker.com/r/curlimages/curl>
## DNS
The primary domain name, `curl.se` is managed by Kirei and is offered over
fault-tolerant anycast servers. High availability and fast access for
everyone.
The actual physical DNS files and origin bind instance is managed by Daniel
Stenberg.
## Mailing lists
The curl related mailing lists are hosted by Haxx AB on `lists.haxx.se` and
are maintained by Daniel Stenberg. This includes the mailman2 and Postfix
instances used for this.
## Email
We use a few rare additional curl related email aliases in the curl domains.
They go through the mail server `mail.haxx.se` maintained by Daniel Stenberg
## Bug-bounty
We run a [bug-bounty](https://curl.se/docs/bugbounty.html) on HackerOne. The
setup runs entirely at https://hackerone.com/curl.
The money part for the bug bounty is sponsored by the [Internet Bug
Bounty](https://hackerone.com/ibb).
## Open Collective
We use [Open Collective](https://opencollective.com/curl) as our "fiscal
host". All money sent to and received by the curl project is managed by Open
Collective.
## Merchandise
We have stickers, coffee mugs and coasters. They are managed by Daniel who
sits on the inventory. The best way to get your hands on curl merchandise is
to attend events where Daniel is physically.
## Chat
Some curl developers, maintainers, users and enthusiasts use IRC for real-time
chat about curl and related topics. This done in the `#curl` channel on the
`libra.chat` IRC network. **Daniel Stenberg** (`bagder`) is registered owner
of the channel. We do not run any IRC servers or services ourselves.
`curelbot` is a service in the channel that shows details about GitHub issues
and pull requests when publicly mentioned using #[number]. The bot is run by
user `TheAssassin`.
There is a Matrix bridge to the IRC channel called `matrix.curl.se`. The
bridge is setup and run by **Sergio Durigan Junior** and **Daniel Stenberg**.

# Building with CMake
This document describes how to configure, build and install curl and libcurl
from source code using the CMake build tool. To build with CMake, you of
course first have to install CMake. The minimum required version of CMake is
specified in the file `CMakeLists.txt` found in the top of the curl source
tree. Once the correct version of CMake is installed you can follow the
instructions below for the platform you are building on.
CMake builds can be configured either from the command line, or from one of
CMake's GUIs.
# Configuring
A CMake configuration of curl is similar to the autotools build of curl.
It consists of the following steps after you have unpacked the source.
We recommend building with CMake on Windows. For instructions on migrating
from the `projects/Windows` Visual Studio solution files, see
[this section](#migrating-from-visual-studio-ide-project-files). For
instructions on migrating from the winbuild builds, see
[the following section](#migrating-from-winbuild-builds).
## Using `cmake`
You can configure for in source tree builds or for a build tree
that is apart from the source tree.
- Build in the source tree.
$ cmake -B .
- Build in a separate directory (parallel to the curl source tree in this
example). The build directory is created for you. This is recommended over
building in the source tree to separate source and build artifacts.
$ cmake -B ../curl-build
For the full list of CMake build configuration variables see
[the corresponding section](#cmake-build-options).
### Fallback for CMake before version 3.13
CMake before version 3.13 does not support the `-B` option. In that case,
you must create the build directory yourself, `cd` to it and run `cmake`
from there:
$ mkdir ../curl-build
$ cd ../curl-build
$ cmake ../curl
If you want to build in the source tree, it is enough to do this:
$ cmake .
### Build system generator selection
You can override CMake's default by using `-G <generator-name>`. For example
on Windows with multiple build systems if you have MinGW-w64 then you could use
`-G "MinGW Makefiles"`.
[List of generator names](https://cmake.org/cmake/help/latest/manual/cmake-generators.7.html).
## Using `ccmake`
CMake comes with a curses based interface called `ccmake`. To run `ccmake`
on a curl use the instructions for the command line cmake, but substitute
`ccmake` for `cmake`.
This brings up a curses interface with instructions on the bottom of the
screen. You can press the "c" key to configure the project, and the "g" key to
generate the project. After the project is generated, you can run make.
## Using `cmake-gui`
CMake also comes with a Qt based GUI called `cmake-gui`. To configure with
`cmake-gui`, you run `cmake-gui` and follow these steps:
1. Fill in the "Where is the source code" combo box with the path to
the curl source tree.
2. Fill in the "Where to build the binaries" combo box with the path to
the directory for your build tree, ideally this should not be the same
as the source tree, but a parallel directory called curl-build or
something similar.
3. Once the source and binary directories are specified, press the
"Configure" button.
4. Select the native build tool that you want to use.
5. At this point you can change any of the options presented in the GUI.
Once you have selected all the options you want, click the "Generate"
button.
# Building
Build (you have to specify the build directory).
$ cmake --build ../curl-build
## Static builds
The CMake build setup is primarily done to work with shared/dynamic third
party dependencies. When linking with shared libraries, the dependency "chain"
is handled automatically by the library loader - on all modern systems.
If you instead link with a static library, you need to provide all the
dependency libraries already at the link command line.
Figuring out all the dependency libraries for a given library is hard, as it
might involve figuring out the dependencies of the dependencies and they vary
between platforms and can change between versions.
When using static dependencies, the build scripts mostly assume that you, the
user, provide all the necessary additional dependency libraries as additional
arguments in the build.
Building statically is not for the faint of heart.
### Fallback for CMake before version 3.13
CMake before version 3.13 does not support the `--build` option. In that
case, you have to `cd` to the build directory and use the building tool that
corresponds to the build files that CMake generated for you. This example
assumes that CMake generates `Makefile`:
$ cd ../curl-build
$ make
# Testing
(The test suite does not yet work with the cmake build)
# Installing
Install to default location (you have to specify the build directory).
$ cmake --install ../curl-build
Do not use `--prefix` to change the installation prefix as the output produced
by the `curl-config` script is determined at CMake configure time. If you want
to set a custom install prefix for curl, set
[`CMAKE_INSTALL_PREFIX`](https://cmake.org/cmake/help/latest/variable/CMAKE_INSTALL_PREFIX.html)
when configuring the CMake build.
### Fallback for CMake before version 3.15
CMake before version 3.15 does not support the `--install` option. In that
case, you have to `cd` to the build directory and use the building tool that
corresponds to the build files that CMake generated for you. This example
assumes that CMake generates `Makefile`:
$ cd ../curl-build
$ make install
# CMake usage
Just as curl can be built and installed using CMake, it can also be used from
CMake.
## Using `find_package`
To locate libcurl from CMake, one can use the standard
[`find_package`](https://cmake.org/cmake/help/latest/command/find_package.html)
command in the typical fashion:
```cmake
find_package(CURL 8.12.0 REQUIRED) # FATAL_ERROR if CURL is not found
```
This invokes the CMake-provided
[FindCURL](https://cmake.org/cmake/help/latest/module/FindCURL.html) find module,
which first performs a search using the `find_package`
[config mode](https://cmake.org/cmake/help/latest/command/find_package.html#config-mode-search-procedure).
This is supported by the `CURLConfig.cmake` CMake config script which is
available if the given CURL was built and installed using CMake.
### Detecting CURL features/protocols
Since version 8.12.0, `CURLConfig.cmake` publishes the supported CURL features
and protocols (see [release notes](https://curl.se/ch/8.12.0.html)). These can
be specified using the `find_package` keywords `COMPONENTS` and
`OPTIONAL_COMPONENTS`, with protocols in all caps, e.g. `HTTPS`, `LDAP`, while
features should be in their original sentence case, e.g. `AsynchDNS`,
`UnixSockets`. If any of the `COMPONENTS` are missing, then CURL is considered
as *not* found.
Here is an example of using `COMPONENTS` and `OPTIONAL_COMPONENTS` in
`find_package` with CURL:
```cmake
# CURL_FOUND is FALSE if no HTTPS but brotli and zstd can be missing
find_package(CURL 8.12.0 COMPONENTS HTTPS OPTIONAL_COMPONENTS brotli zstd)
```
One can also check the defined `CURL_SUPPORTS_<feature-or-protocol>` variables
if a particular feature/protocol is supported. For example:
```cmake
# check HTTPS
if(CURL_SUPPORTS_HTTPS)
message(STATUS "CURL supports HTTPS")
else()
message(STATUS "CURL does NOT support HTTPS")
endif()
```
### Linking against libcurl
To link a CMake target against libcurl one can use
[`target_link_libraries`](https://cmake.org/cmake/help/latest/command/target_link_libraries.html)
as usual:
```cmake
target_link_libraries(my_target PRIVATE CURL::libcurl)
```

## Feature detection variables
By default this CMake build script detects the version of some dependencies
using `check_symbol_exists`. Those checks do not work in the case that both
CURL and its dependency are included as sub-projects in a larger build using
`FetchContent`. To support that case, additional variables may be defined by
the parent project, ideally in the "extra" find package redirect file:
<https://cmake.org/cmake/help/latest/module/FetchContent.html#integrating-with-find-package>
Available variables:
- `HAVE_GNUTLS_SRP`: `gnutls_srp_verifier` present in GnuTLS.
- `HAVE_GSS_C_NT_HOSTBASED_SERVICE`: `GSS_C_NT_HOSTBASED_SERVICE` present in GSS/Heimdal/Kerberos.
- `HAVE_LDAP_INIT_FD`: `ldap_init_fd` present in LDAP library.
- `HAVE_LDAP_URL_PARSE`: `ldap_url_parse` present in LDAP library.
- `HAVE_OPENSSL_SRP`: `SSL_CTX_set_srp_username` present in OpenSSL (or fork).
- `HAVE_QUICHE_CONN_SET_QLOG_FD`: `quiche_conn_set_qlog_fd` present in quiche.
- `HAVE_RUSTLS_SUPPORTED_HPKE`: `rustls_supported_hpke` present in Rustls (unused if Rustls is detected via `pkg-config`).
- `HAVE_SSL_SET0_WBIO`: `SSL_set0_wbio` present in OpenSSL (or fork).
- `HAVE_SSL_SET1_ECH_CONFIG_LIST`: `SSL_set1_ech_config_list` present in OpenSSL (or fork).
- `HAVE_SSL_SET_QUIC_TLS_CBS`: `SSL_set_quic_tls_cbs` in OpenSSL.
- `HAVE_SSL_SET_QUIC_USE_LEGACY_CODEPOINT`: `SSL_set_quic_use_legacy_codepoint` in OpenSSL fork.
- `HAVE_WOLFSSL_BIO_NEW`: `wolfSSL_BIO_new` present in wolfSSL.
- `HAVE_WOLFSSL_BIO_SET_SHUTDOWN`: `wolfSSL_BIO_set_shutdown` present in wolfSSL.
- `HAVE_WOLFSSL_CTX_GENERATEECHCONFIG`: `wolfSSL_CTX_GenerateEchConfig` present in wolfSSL.
- `HAVE_WOLFSSL_DES_ECB_ENCRYPT`: `wolfSSL_DES_ecb_encrypt` present in wolfSSL.
- `HAVE_WOLFSSL_GET_PEER_CERTIFICATE`: `wolfSSL_get_peer_certificate` present in wolfSSL.
- `HAVE_WOLFSSL_SET_QUIC_USE_LEGACY_CODEPOINT`:
`wolfSSL_set_quic_use_legacy_codepoint` present in wolfSSL.
- `HAVE_WOLFSSL_USEALPN`: `wolfSSL_UseALPN` present in wolfSSL.
For each of the above variables, if the variable is *defined* (either to `ON`
or `OFF`), the symbol detection is skipped. If the variable is *not defined*,
the feature detection is performed.
Note: These variables are internal and subject to change.
# Migrating from Visual Studio IDE Project Files
We recommend using CMake to build curl with MSVC.
The project build files reside in project/Windows/VC\* for VS2010, VS2012 and
VS2013.
These CMake Visual Studio generators require CMake v3.24 or older. You can
download them from <https://cmake.org/files/v3.24/>.
You can also use `-G "NMake Makefiles"`, which is supported by all CMake
versions.
Configuration element | Equivalent CMake options
:-------------------------------- | :--------------------------------
`VC10` | `-G "Visual Studio 10 2010"`
`VC11` | `-G "Visual Studio 11 2012"`
`VC12` | `-G "Visual Studio 12 2013"`
`x64` | `-A x64`
`Win32` | `-A Win32`
`DLL` | `BUILD_SHARED_LIBS=ON`, `BUILD_STATIC_LIBS=OFF`, (default)
`LIB` | `BUILD_SHARED_LIBS=OFF`, `BUILD_STATIC_LIBS=ON`
`Debug` | `CMAKE_BUILD_TYPE=Debug` (`-G "NMake Makefiles"` only)
`Release` | `CMAKE_BUILD_TYPE=Release` (`-G "NMake Makefiles"` only)
`DLL Windows SSPI` | `CURL_USE_SCHANNEL=ON` (with SSPI enabled by default)
`DLL OpenSSL` | `CURL_USE_OPENSSL=ON`, optional: `OPENSSL_ROOT_DIR`, `OPENSSL_USE_STATIC_LIBS=ON`
`DLL libssh2` | `CURL_USE_LIBSSH2=ON`, optional: `LIBSSH2_INCLUDE_DIR`, `LIBSSH2_LIBRARY`
`DLL WinIDN` | `USE_WIN32_IDN=ON`
For example these commands:
> cd projects
> ./generate.bat VC12
> msbuild "-property:Configuration=DLL Debug - DLL Windows SSPI - DLL WinIDN" Windows/VC12/curl-all.sln
translate to:
> cmake . -G "Visual Studio 12 2013" -A x64 -DCURL_USE_SCHANNEL=ON -DUSE_WIN32_IDN=ON -DCURL_USE_LIBPSL=OFF
> cmake --build . --config Debug --parallel
We do *not* specify `-DCMAKE_BUILD_TYPE=Debug` here as we might do for the
`"NMake Makefiles"` generator because the Visual Studio generators are
[multi-config generators](https://cmake.org/cmake/help/latest/prop_gbl/GENERATOR_IS_MULTI_CONFIG.html)
and therefore ignore the value of `CMAKE_BUILD_TYPE`.
# Migrating from winbuild builds
We recommend CMake to build curl with MSVC. The winbuild build system is
deprecated and is going to be removed in September 2025 in favor of the CMake
build system.
In CMake you can customize the path of dependencies by passing the absolute
header path and the full path of the library via `*_INCLUDE_DIR` and
`*_LIBRARY` options (see the complete list in the option listing above).
The full path to the library can point to a static library or an import
library, which defines if the dependency is linked as a dll or statically.
For OpenSSL this works
[differently](https://cmake.org/cmake/help/latest/module/FindOpenSSL.html):
You can pass the root directory of the OpenSSL installation via
`OPENSSL_ROOT_DIR`, then pass `OPENSSL_USE_STATIC_LIBS=ON` to select static
libs.
winbuild options | Equivalent CMake options
:-------------------------------- | :--------------------------------
`DEBUG` | `CMAKE_BUILD_TYPE=Debug`
`GEN_PDB` | `CMAKE_EXE_LINKER_FLAGS=/Fd<path>`, `CMAKE_SHARED_LINKER_FLAGS=/Fd<path>`
`LIB_NAME_DLL`, `LIB_NAME_STATIC` | `IMPORT_LIB_SUFFIX`, `LIBCURL_OUTPUT_NAME`, `STATIC_LIB_SUFFIX`
`VC`: `<N>` | see the CMake [Visual Studio generators](https://cmake.org/cmake/help/latest/manual/cmake-generators.7.html#visual-studio-generators)
`MACHINE`: `x64`, `x86` | `-A x64`, `-A Win32`
`MODE`: `dll`, `static` | `BUILD_SHARED_LIBS=ON/OFF`, `BUILD_STATIC_LIBS=ON/OFF`, `BUILD_STATIC_CURL=ON/OFF` (default: dll)
`RTLIBCFG`: `static` | `CURL_STATIC_CRT=ON`
`ENABLE_IDN` | `USE_WIN32_IDN=ON`
`ENABLE_IPV6` | `ENABLE_IPV6=ON`
`ENABLE_MSH3` | `USE_MSH3=ON`
`ENABLE_NGHTTP2` | `USE_NGHTTP2=ON`
`ENABLE_OPENSSL_AUTO_LOAD_CONFIG` | `CURL_DISABLE_OPENSSL_AUTO_LOAD_CONFIG=OFF` (default)
`ENABLE_SCHANNEL` | `CURL_USE_SCHANNEL=ON`
`ENABLE_SSPI` | `CURL_WINDOWS_SSPI=ON` (default with Schannel)
`ENABLE_UNICODE` | `ENABLE_UNICODE=ON`
`WITH_PREFIX` | `CMAKE_INSTALL_PREFIX=<path>`
`WITH_DEVEL` | see individual `*_INCLUDE_DIR` and `*_LIBRARY` options and `OPENSSL_ROOT_DIR`
`WITH_CARES`, `CARES_PATH` | `ENABLE_ARES=ON`, optional: `CARES_INCLUDE_DIR`, `CARES_LIBRARY`
`WITH_MBEDTLS`, `MBEDTLS_PATH` | `CURL_USE_MBEDTLS=ON`, optional: `MBEDTLS_INCLUDE_DIR`, `MBEDTLS_LIBRARY`, `MBEDX509_LIBRARY`, `MBEDCRYPTO_LIBRARY`
`WITH_MSH3`, `MSH_PATH` | `USE_MSH3=ON`, optional: `MSH3_INCLUDE_DIR`, `MSH3_LIBRARY`
`WITH_NGHTTP2`, `NGHTTP2_PATH` | `USE_NGHTTP2=ON`, optional: `NGHTTP2_INCLUDE_DIR`, `NGHTTP2_LIBRARY`
`WITH_SSH`, `SSH_PATH` | `CURL_USE_LIBSSH=ON`, optional: `LIBSSH_INCLUDE_DIR`, `LIBSSH_LIBRARY`
`WITH_SSH2`, `SSH2_PATH` | `CURL_USE_LIBSSH2=ON`, optional: `LIBSSH2_INCLUDE_DIR`, `LIBSSH2_LIBRARY`
`WITH_SSL`, `SSL_PATH` | `CURL_USE_OPENSSL=ON`, optional: `OPENSSL_ROOT_DIR`, `OPENSSL_USE_STATIC_LIBS=ON`
`WITH_WOLFSSL`, `WOLFSSL_PATH` | `CURL_USE_WOLFSSL=ON`, optional: `WOLFSSL_INCLUDE_DIR`, `WOLFSSL_LIBRARY`
`WITH_ZLIB`, `ZLIB_PATH` | `CURL_ZLIB=ON`, optional: `ZLIB_INCLUDE_DIR`, `ZLIB_LIBRARY`
For example this command-line:
> nmake -f Makefile.vc VC=17 MACHINE=x64 DEBUG=ON mode=dll SSL_PATH=C:\OpenSSL WITH_SSL=dll ENABLE_UNICODE=ON
translates to:
> cmake . -G "Visual Studio 17 2022" -A x64 -DBUILD_SHARED_LIBS=ON -DOPENSSL_ROOT_DIR=C:\OpenSSL -DCURL_USE_OPENSSL=ON -DENABLE_UNICODE=ON -DCURL_USE_LIBPSL=OFF
> cmake --build . --config Debug
We use `--config` with `cmake --build` because the Visual Studio CMake
generators are multi-config and therefore ignore `CMAKE_BUILD_TYPE`.

# How to install curl and libcurl
## Installing Binary Packages
Lots of people download binary distributions of curl and libcurl. This
document does not describe how to install curl or libcurl using such a binary
package. This document describes how to compile, build and install curl and
libcurl from [source code](https://curl.se/download.html).
## Building using vcpkg
You can download and install curl and libcurl using the [vcpkg](https://github.com/Microsoft/vcpkg/) dependency manager:
git clone https://github.com/Microsoft/vcpkg.git
cd vcpkg
./bootstrap-vcpkg.sh
./vcpkg integrate install
vcpkg install curl[tool]
The curl port in vcpkg is kept up to date by Microsoft team members and
community contributors. If the version is out of date, please [create an issue
or pull request](https://github.com/Microsoft/vcpkg) on the vcpkg repository.
## Building from git
If you get your code off a git repository instead of a release tarball, see
the [GIT-INFO.md](https://github.com/curl/curl/blob/master/GIT-INFO.md) file in the root directory for specific instructions on how
to proceed.
# Unix
A normal Unix installation is made in three or four steps (after you have
unpacked the source archive):
./configure --with-openssl [--with-gnutls --with-wolfssl]
make
make test (optional)
make install
(Adjust the configure line accordingly to use the TLS library you want.)
You probably need to be root when doing the last command.
Get a full listing of all available configure options by invoking it like:
./configure --help
If you want to install curl in a different file hierarchy than `/usr/local`,
specify that when running configure:
./configure --prefix=/path/to/curl/tree
If you have write permission in that directory, you can do 'make install'
without being root. An example of this would be to make a local install in
your own home directory:
./configure --prefix=$HOME
make
make install
The configure script always tries to find a working SSL library unless
explicitly told not to. If you have OpenSSL installed in the default search
path for your compiler/linker, you do not need to do anything special. If you
have OpenSSL installed in `/usr/local/ssl`, you can run configure like:
./configure --with-openssl
If you have OpenSSL installed somewhere else (for example, `/opt/OpenSSL`) and
you have pkg-config installed, set the pkg-config path first, like this:
env PKG_CONFIG_PATH=/opt/OpenSSL/lib/pkgconfig ./configure --with-openssl
Without pkg-config installed, use this:
./configure --with-openssl=/opt/OpenSSL
If you insist on forcing a build without SSL support, you can run configure
like this:
./configure --without-ssl
If you have OpenSSL installed, but with the libraries in one place and the
header files somewhere else, you have to set the `LDFLAGS` and `CPPFLAGS`
environment variables prior to running configure. Something like this should
work:
CPPFLAGS="-I/path/to/ssl/include" LDFLAGS="-L/path/to/ssl/lib" ./configure
If you have shared SSL libs installed in a directory where your runtime
linker does not find them (which usually causes configure failures), you can
provide this option to gcc to set a hard-coded path to the runtime linker:
LDFLAGS=-Wl,-R/usr/local/ssl/lib ./configure --with-openssl
## Static builds
To force a static library compile, disable the shared library creation by
running configure like:
./configure --disable-shared
The configure script is primarily done to work with shared/dynamic third party
dependencies. When linking with shared libraries, the dependency "chain" is
handled automatically by the library loader - on all modern systems.
If you instead link with a static library, you need to provide all the
dependency libraries already at the link command line.
Figuring out all the dependency libraries for a given library is hard, as it
might involve figuring out the dependencies of the dependencies and they vary
between platforms and change between versions.
When using static dependencies, the build scripts mostly assume that you, the
user, provide all the necessary additional dependency libraries as additional
arguments in the build. With configure, by setting `LIBS` or `LDFLAGS` on the
command line.
Building statically is not for the faint of heart.
## Debug
If you are a curl developer and use gcc, you might want to enable more debug
options with the `--enable-debug` option.
curl can be built to use a whole range of libraries to provide various useful
services, and configure tries to auto-detect a decent default. If you want to
alter it, you can select how to deal with each individual library.
## Select TLS backend
These options are provided to select the TLS backend to use.
- AmiSSL: `--with-amissl`
- GnuTLS: `--with-gnutls`.
- mbedTLS: `--with-mbedtls`
- OpenSSL: `--with-openssl` (also for BoringSSL, AWS-LC, LibreSSL, and quictls)
- rustls: `--with-rustls`
- Schannel: `--with-schannel`
- wolfSSL: `--with-wolfssl`
You can build curl with *multiple* TLS backends at your choice, but some TLS
backends cannot be combined: if you build with an OpenSSL fork (or wolfSSL),
you cannot add another OpenSSL fork (or wolfSSL) simply because they have
conflicting identical symbol names.
When you build with multiple TLS backends, you can select the active one at
runtime when curl starts up.
## MultiSSL and HTTP/3
HTTP/3 needs QUIC and QUIC needs TLS. Building libcurl with HTTP/3 and QUIC
support is not compatible with the MultiSSL feature: they are mutually
exclusive. If you need MultiSSL in your build, you cannot have HTTP/3 support
and vice versa.
libcurl can only use a single TLS library with QUIC and that *same* TLS
library needs to be used for the other TLS using protocols.
## Configure finding libs in wrong directory
When the configure script checks for third-party libraries, it adds those
directories to the `LDFLAGS` variable and then tries linking to see if it
works. When successful, the found directory is kept in the `LDFLAGS` variable
when the script continues to execute and do more tests and possibly check for
more libraries.
This can make subsequent checks for libraries wrongly detect another
installation in a directory that was previously added to `LDFLAGS` by another
library check.
# Windows
Building for Windows XP is required as a minimum.
You can build curl with:
- Microsoft Visual Studio 2008 v9.0 or later (`_MSC_VER >= 1500`)
- MinGW-w64
## Building Windows DLLs and C runtime (CRT) linkage issues
As a general rule, building a DLL with static CRT linkage is highly
discouraged, and intermixing CRTs in the same app is something to avoid at
any cost.
Reading and comprehending Microsoft Knowledge Base articles KB94248 and
KB140584 is a must for any Windows developer. Especially important is full
understanding if you are not going to follow the advice given above.
- [How To Use the C Runtime](https://support.microsoft.com/help/94248/how-to-use-the-c-run-time)
- [Runtime Library Compiler Options](https://docs.microsoft.com/cpp/build/reference/md-mt-ld-use-run-time-library)
- [Potential Errors Passing CRT Objects Across DLL Boundaries](https://docs.microsoft.com/cpp/c-runtime-library/potential-errors-passing-crt-objects-across-dll-boundaries)
If your app is misbehaving in some strange way, or it is suffering from memory
corruption, before asking for further help, please try first to rebuild every
single library your app uses as well as your app using the debug
multi-threaded dynamic C runtime.
If you get linkage errors read section 5.7 of the FAQ document.
## Cygwin
Almost identical to the Unix installation. Essentially run the configure script in the
curl source tree root with `sh configure`, then run `make`.
To expand on building with `cygwin` first ensure it is in your path, and there are no
conflicting tools (*i.e. Chocolatey with sed package*). If so move `cygwin` ahead of any items
in your path that would conflict with `cygwin` commands, making sure you have the `sh`
executable in `/bin/` or you see the configure fail toward the end.
Download the setup installer from
[`cygwin`](https://cygwin.com/) to begin. Additional `cygwin`
packages are needed for the install. For more on installing packages visit
[`cygwin setup`](https://www.cygwin.com/faq/faq.html#faq.setup.cli).
Either run setup-x86_64.exe, then search and select packages individually, or try:
setup-x86_64.exe -P binutils -P gcc-core -P libpsl-devel -P libtool -P perl -P make
If the latter, matching packages should appear in the install rows (*is fickle though*) after selecting
the download site i.e. `https://mirrors.kernel.org`. In either case, follow the GUI prompts
until you reach the "Select Packages" window; then select packages, click next, and finish
the `cygwin` package installation.
Download the latest version of the `cygwin` packages required (*and suggested*) for a successful install:
<details>
<summary>Package List</summary>
```
binutil - required
gcc-core - required
libpsl-devel - required
libtool - required
perl - required
make - required
- NOTE - if there is an error regarding make, open the cygwin terminal, and run:
ln -s /usr/bin/make /usr/bin/gmake
```
</details>
Once all the packages have been installed, begin the process of installing curl from the source code:
<details>
<summary>configure_options</summary>
```
--with-gnutls
--with-mbedtls
--with-openssl (also works for OpenSSL forks)
--with-rustls
--with-wolfssl
--without-ssl
```
</details>
1. `sh configure <configure_options>`
2. `make`
If any error occurs during curl installation, try:
- reinstalling the required `cygwin` packages from the list above
- temporarily move `cygwin` to the top of your path
- install all of the suggested `cygwin` packages
## MS-DOS
You can use either autotools or cmake:
./configure \
CC=/path/to/djgpp/bin/i586-pc-msdosdjgpp-gcc \
AR=/path/to/djgpp/bin/i586-pc-msdosdjgpp-ar \
RANLIB=/path/to/djgpp/bin/i586-pc-msdosdjgpp-ranlib \
WATT_ROOT=/path/to/djgpp/net/watt \
--host=i586-pc-msdosdjgpp \
--with-openssl=/path/to/djgpp \
--with-zlib=/path/to/djgpp \
--without-libpsl \
--disable-shared
cmake . \
-DCMAKE_SYSTEM_NAME=DOS \
-DCMAKE_C_COMPILER_TARGET=i586-pc-msdosdjgpp \
-DCMAKE_C_COMPILER=/path/to/djgpp/bin/i586-pc-msdosdjgpp-gcc \
-DWATT_ROOT=/path/to/djgpp/net/watt \
-DOPENSSL_INCLUDE_DIR=/path/to/djgpp/include \
-DOPENSSL_SSL_LIBRARY=/path/to/djgpp/lib/libssl.a \
-DOPENSSL_CRYPTO_LIBRARY=/path/to/djgpp/lib/libcrypto.a \
-DZLIB_INCLUDE_DIR=/path/to/djgpp/include \
-DZLIB_LIBRARY=/path/to/djgpp/lib/libz.a \
-DCURL_USE_LIBPSL=OFF
Notes:
- Requires DJGPP 2.04 or upper.
- Compile Watt-32 (and OpenSSL) with the same version of DJGPP. Otherwise
things go wrong because things like FS-extensions and `errno` values have
been changed between releases.
## AmigaOS
You can use either autotools or cmake:
./configure \
CC=/opt/amiga/bin/m68k-amigaos-gcc \
AR=/opt/amiga/bin/m68k-amigaos-ar \
RANLIB=/opt/amiga/bin/m68k-amigaos-ranlib \
--host=m68k-amigaos \
--with-amissl \
CFLAGS='-O0 -msoft-float -mcrt=clib2' \
CPPFLAGS=-I/path/to/AmiSSL/Developer/include \
LDFLAGS=-L/path/to/AmiSSL/Developer/lib/AmigaOS3 \
LIBS='-lnet -lm -latomic' \
--without-libpsl \
--disable-shared
cmake . \
-DAMIGA=1 \
-DCMAKE_SYSTEM_NAME=Generic \
-DCMAKE_C_COMPILER_TARGET=m68k-unknown-amigaos \
-DCMAKE_C_COMPILER=/opt/amiga/bin/m68k-amigaos-gcc \
-DCMAKE_C_FLAGS='-O0 -msoft-float -mcrt=clib2' \
-DAMISSL_INCLUDE_DIR=/path/to/AmiSSL/Developer/include \
-DAMISSL_STUBS_LIBRARY=/path/to/AmiSSL/Developer/lib/AmigaOS3/libamisslstubs.a \
-DAMISSL_AUTO_LIBRARY=/path/to/AmiSSL/Developer/lib/AmigaOS3/libamisslauto.a \
-DCURL_USE_LIBPSL=OFF
## Disabling Specific Protocols in Windows builds
The configure utility, unfortunately, is not available for the Windows
environment, therefore, you cannot use the various disable-protocol options of
the configure utility on this platform.
You can use specific defines to disable specific protocols and features. See
[CURL-DISABLE](https://github.com/curl/curl/blob/master/docs/CURL-DISABLE.md)
for the full list.
If you want to set any of these defines you have the following options:
- Modify `lib/config-win32.h`
- Modify `lib/curl_setup.h`
- Modify `winbuild/Makefile.vc`
- Modify the "Preprocessor Definitions" in the libcurl project
Note: The pre-processor settings can be found using the Visual Studio IDE
under "Project -> Properties -> Configuration Properties -> C/C++ ->
Preprocessor".
## Using BSD-style lwIP instead of Winsock TCP/IP stack in Windows builds
In order to compile libcurl and curl using BSD-style lwIP TCP/IP stack it is
necessary to make the definition of the preprocessor symbol `USE_LWIPSOCK`
visible to libcurl and curl compilation processes. To set this definition you
have the following alternatives:
- Modify `lib/config-win32.h`
- Modify `winbuild/Makefile.vc`
- Modify the "Preprocessor Definitions" in the libcurl project
Note: The pre-processor settings can be found using the Visual Studio IDE
under "Project -> Properties -> Configuration Properties -> C/C++ ->
Preprocessor".
Once that libcurl has been built with BSD-style lwIP TCP/IP stack support, in
order to use it with your program it is mandatory that your program includes
lwIP header file `<lwip/opt.h>` (or another lwIP header that includes this)
before including any libcurl header. Your program does not need the
`USE_LWIPSOCK` preprocessor definition which is for libcurl internals only.
Compilation has been verified with lwIP 1.4.0.
This BSD-style lwIP TCP/IP stack support must be considered experimental given
that it has been verified that lwIP 1.4.0 still needs some polish, and libcurl
might yet need some additional adjustment.
## Important static libcurl usage note
When building an application that uses the static libcurl library on Windows,
you must add `-DCURL_STATICLIB` to your `CFLAGS`. Otherwise the linker looks
for dynamic import symbols.
## Legacy Windows and SSL
Schannel (from Windows SSPI), is the native SSL library in Windows. However,
Schannel in Windows <= XP is unable to connect to servers that no longer
support the legacy handshakes and algorithms used by those versions. If you
are using curl in one of those earlier versions of Windows you should choose
another SSL backend such as OpenSSL.
# Android
When building curl for Android you can you CMake or curl's `configure` script.
Before you can build curl for Android, you need to install the Android NDK
first. This can be done using the SDK Manager that is part of Android Studio.
Once you have installed the Android NDK, you need to figure out where it has
been installed and then set up some environment variables before launching
the build.
Examples to compile for `aarch64` and API level 29:
with CMake, where `ANDROID_NDK_HOME` points into your NDK:
cmake . \

```
When building on Linux or targeting other API levels or architectures, you need
to adjust those variables accordingly. After that you can build curl like this:
./configure --host aarch64-linux-android --with-pic --disable-shared
Note that this does not give you SSL/TLS support. If you need SSL/TLS, you
have to build curl with an SSL/TLS library, e.g. OpenSSL, because it is
impossible for curl to access Android's native SSL/TLS layer. To build curl
for Android using OpenSSL, follow the OpenSSL build instructions and then
install `libssl.a` and `libcrypto.a` to `$TOOLCHAIN/sysroot/usr/lib` and copy
`include/openssl` to `$TOOLCHAIN/sysroot/usr/include`. Now you can build curl
for Android using OpenSSL like this:
```bash
LIBS="-lssl -lcrypto -lc++" # For OpenSSL/BoringSSL. In general, you need to the SSL/TLS layer's transitive dependencies if you are linking statically.
./configure --host aarch64-linux-android --with-pic --disable-shared --with-openssl="$TOOLCHAIN/sysroot/usr"
```
# IBM i
For IBM i (formerly OS/400), you can use curl in two different ways:
- Natively, running in the **ILE**. The obvious use is being able to call curl
from ILE C or RPG applications.
- You need to build this from source. See `packages/OS400/README` for the ILE
specific build instructions.
- In the **PASE** environment, which runs AIX programs. curl is built as it
would be on AIX.
- IBM provides builds of curl in their Yum repository for PASE software.
- To build from source, follow the Unix instructions.
There are some additional limitations and quirks with curl on this platform;
they affect both environments.
## Multi-threading notes
By default, jobs in IBM i does not start with threading enabled. (Exceptions
include interactive PASE sessions started by `QP2TERM` or SSH.) If you use
curl in an environment without threading when options like asynchronous DNS
were enabled, you get messages like:
```
getaddrinfo() thread failed to start
```
Do not panic. curl and your program are not broken. You can fix this by:
- Set the environment variable `QIBM_MULTI_THREADED` to `Y` before starting
your program. This can be done at whatever scope you feel is appropriate.
- Alternatively, start the job with the `ALWMLTTHD` parameter set to `*YES`.
# Cross compile
Download and unpack the curl package.
`cd` to the new directory. (e.g. `cd curl-7.12.3`)
Set environment variables to point to the cross-compile toolchain and call
configure with any options you need. Be sure and specify the `--host` and
`--build` parameters at configuration time. The following script is an example
of cross-compiling for the IBM 405GP PowerPC processor using the toolchain on
Linux.
```bash
#! /bin/sh
export PATH=$PATH:/opt/hardhat/devkit/ppc/405/bin
export CPPFLAGS="-I/opt/hardhat/devkit/ppc/405/target/usr/include"
export AR=ppc_405-ar
export AS=ppc_405-as
export LD=ppc_405-ld
export RANLIB=ppc_405-ranlib
export CC=ppc_405-gcc
export NM=ppc_405-nm
./configure --target=powerpc-hardhat-linux
--host=powerpc-hardhat-linux
--build=i586-pc-linux-gnu
--prefix=/opt/hardhat/devkit/ppc/405/target/usr/local
--exec-prefix=/usr/local
```
The `--prefix` parameter specifies where curl gets installed. If `configure`
completes successfully, do `make` and `make install` as usual.
In some cases, you may be able to simplify the above commands to as little as:
./configure --host=ARCH-OS
# REDUCING SIZE
There are a number of configure options that can be used to reduce the size of
libcurl for embedded applications where binary size is an important factor.
First, be sure to set the `CFLAGS` variable when configuring with any relevant
compiler optimization flags to reduce the size of the binary. For gcc, this
would mean at minimum the `-Os` option, and others like the following that
may be relevant in some environments: `-march=X`, `-mthumb`, `-m32`,
`-mdynamic-no-pic`, `-flto`, `-fdata-sections`, `-ffunction-sections`,
`-fno-unwind-tables`, `-fno-asynchronous-unwind-tables`,
`-fno-record-gcc-switches`, `-fsection-anchors`, `-fno-plt`,
`-Wl,--gc-sections`, `-Wl,-Bsymbolic`, `-Wl,-s`,
For example, this is how to combine a few of these options:
./configure CC=gcc CFLAGS='-Os -ffunction-sections' LDFLAGS='-Wl,--gc-sections'...
Note that newer compilers often produce smaller code than older versions
due to improved optimization.
Be sure to specify as many `--disable-` and `--without-` flags on the
configure command-line as you can to disable all the libcurl features that you
know your application is not going to need. Besides specifying the
`--disable-PROTOCOL` flags for all the types of URLs your application do not
use, here are some other flags that can reduce the size of the library by
disabling support for some features (run `./configure --help` to see them all):
- `--disable-aws` (cryptographic authentication)
- `--disable-basic-auth` (cryptographic authentication)
- `--disable-bearer-auth` (cryptographic authentication)
- `--disable-digest-auth` (cryptographic authentication)
- `--disable-http-auth` (all HTTP authentication)
- `--disable-kerberos-auth` (cryptographic authentication)
- `--disable-negotiate-auth` (cryptographic authentication)
- `--disable-ntlm` (NTLM authentication)
- `--disable-alt-svc` (HTTP Alt-Svc)
- `--disable-ares` (the C-ARES DNS library)
- `--disable-cookies` (HTTP cookies)
- `--disable-dateparse` (date parsing for time conditionals)
- `--disable-dnsshuffle` (internal server load spreading)
- `--disable-doh` (DNS-over-HTTP)
- `--disable-form-api` (POST form API)
- `--disable-get-easy-options` (lookup easy options at runtime)
- `--disable-headers-api` (API to access headers)
- `--disable-hsts` (HTTP Strict Transport Security)
- `--disable-ipv6` (IPv6)
- `--disable-libcurl-option` (--libcurl C code generation support)
- `--disable-manual` (--manual built-in documentation)
- `--disable-mime` (MIME API)
- `--disable-netrc` (.netrc file)
- `--disable-progress-meter` (graphical progress meter in library)
- `--disable-proxy` (HTTP and SOCKS proxies)
- `--disable-socketpair` (socketpair for asynchronous name resolving)
- `--disable-threaded-resolver` (threaded name resolver)
- `--disable-tls-srp` (Secure Remote Password authentication for TLS)
- `--disable-unix-sockets` (Unix sockets)
- `--disable-verbose` (eliminates debugging strings and error code strings)
- `--disable-versioned-symbols` (versioned symbols)
- `--enable-symbol-hiding` (eliminates unneeded symbols in the shared library)
- `--without-brotli` (Brotli on-the-fly decompression)
- `--without-libpsl` (Public Suffix List in cookies)
- `--without-nghttp2` (HTTP/2 using nghttp2)
- `--without-ngtcp2` (HTTP/2 using ngtcp2)
- `--without-zstd` (Zstd on-the-fly decompression)
- `--without-libidn2` (internationalized domain names)
- `--without-librtmp` (RTMP)
- `--without-ssl` (SSL/TLS)
- `--without-zlib` (gzip/deflate on-the-fly decompression)
Be sure also to strip debugging symbols from your binaries after compiling
using 'strip' or an option like `-s`. If space is really tight, you may be able
to gain a few bytes by removing some unneeded sections of the shared library
using the -R option to objcopy (e.g. the .comment section).
Using these techniques it is possible to create a basic HTTP-only libcurl
shared library for i386 Linux platforms that is only 137 KiB in size
(as of libcurl version 8.13.0, using gcc 14.2.0).
You may find that statically linking libcurl to your application results in a
lower total size than dynamically linking.
The curl test harness can detect the use of some, but not all, of the
`--disable` statements suggested above. Use of these can cause tests relying
on those features to fail. The test harness can be manually forced to skip the
relevant tests by specifying certain key words on the `runtests.pl` command
line. Following is a list of appropriate key words for those configure options
that are not automatically detected:
- `--disable-cookies` !cookies
- `--disable-dateparse` !RETRY-AFTER !`CURLOPT_TIMECONDITION` !`CURLINFO_FILETIME` !`If-Modified-Since` !`curl_getdate` !`-z`
- `--disable-libcurl-option` !`--libcurl`
- `--disable-verbose` !verbose\ logs

# curl internals
The canonical libcurl internals documentation is now in the [everything
curl](https://everything.curl.dev/internals) book. This file lists supported
versions of libs and build tools.
## Portability
We write curl and libcurl to compile with C89 compilers on 32-bit and up
machines. Most of libcurl assumes more or less POSIX compliance but that is
not a requirement.
We write libcurl to build and work with lots of third party tools, and we
want it to remain functional and buildable with these and later versions
(older versions may still work but is not what we work hard to maintain):
## Dependencies
We aim to support these or later versions.
- OpenSSL 1.0.2a
- LibreSSL 2.9.1
- GnuTLS 3.1.10
- zlib 1.2.5.2
- libssh2 1.2.8
- c-ares 1.6.0
- libssh 0.9.0
- libidn2 2.0.0
- wolfSSL 3.4.6
- OpenLDAP 2.0
- MIT Kerberos 1.2.4
- Heimdal ?
- nghttp2 1.15.0
- Winsock 2.2 (on Windows 95+ and Windows CE .NET 4.1+)
## Build tools
When writing code (mostly for generating stuff included in release tarballs)
we use a few "build tools" and we make sure that we remain functional with
these versions:
- GNU Libtool 1.4.2
- GNU Autoconf 2.59
- GNU Automake 1.7
- GNU M4 1.4
- perl 5.8
- roffit 0.5
- cmake 3.7
Library Symbols
===============
All symbols used internally in libcurl must use a `Curl_` prefix if they are
used in more than a single file. Single-file symbols must be made static.
Public ("exported") symbols must use a `curl_` prefix. Public API functions
are marked with `CURL_EXTERN` in the public header files so that all others
can be hidden on platforms where this is possible.

# IPFS
For an overview about IPFS, visit the [IPFS project site](https://ipfs.tech/).
In IPFS there are two protocols. IPFS and IPNS (their workings are explained in detail [here](https://docs.ipfs.tech/concepts/)). The ideal way to access data on the IPFS network is through those protocols. For example to access the Big Buck Bunny video the ideal way to access it is like: `ipfs://bafybeigagd5nmnn2iys2f3doro7ydrevyr2mzarwidgadawmamiteydbzi`
## IPFS Gateways
IPFS Gateway acts as a bridge between traditional HTTP clients and IPFS.
IPFS Gateway specifications of HTTP semantics can be found [here](https://specs.ipfs.tech/http-gateways/).
### Deserialized responses
By default, a gateway acts as a bridge between traditional HTTP clients and IPFS and performs necessary hash verification and deserialization. Through such gateway, users can download files, directories, and other content-addressed data stored with IPFS or IPNS as if they were stored in a traditional web server.
### Verifiable responses
By explicitly requesting [application/vnd.ipld.raw](https://www.iana.org/assignments/media-types/application/vnd.ipld.raw) or [application/vnd.ipld.car](https://www.iana.org/assignments/media-types/application/vnd.ipld.car) responses, by means defined in [Trustless Gateway Specification](https://specs.ipfs.tech/http-gateways/trustless-gateway/), the user is able to fetch raw content-addressed data and [perform hash verification themselves](https://docs.ipfs.tech/reference/http/gateway/#trustless-verifiable-retrieval).
This enables users to use untrusted, public gateways without worrying they might return invalid/malicious bytes.
## IPFS and IPNS protocol handling
There are various ways to access data from the IPFS network. One such way is
through the concept of public
"[gateways](https://docs.ipfs.tech/concepts/ipfs-gateway/#overview)". The
short version is that entities can offer gateway services. An example here
that is hosted by Protocol Labs (who also makes IPFS) is `dweb.link` and
`ipfs.io`. Both sites expose gateway functionality. Getting a file through
`ipfs.io` looks like this:
`https://ipfs.io/ipfs/bafybeigagd5nmnn2iys2f3doro7ydrevyr2mzarwidgadawmamiteydbzi`
If you were to be [running your own IPFS
node](https://docs.ipfs.tech/how-to/command-line-quick-start/) then you, by
default, also have a [local gateway](https://specs.ipfs.tech/http-gateways/)
running. In its default configuration the earlier example would then also work
in this link:
`http://127.0.0.1:8080/ipfs/bafybeigagd5nmnn2iys2f3doro7ydrevyr2mzarwidgadawmamiteydbzi`
## cURL handling of the IPFS protocols
The IPFS integration in cURL hides this gateway logic for you. Instead of
providing a full URL to a file on IPFS like this:
```
curl http://127.0.0.1:8080/ipfs/bafybeigagd5nmnn2iys2f3doro7ydrevyr2mzarwidgadawmamiteydbzi
```
You can provide it with the IPFS protocol instead:
```
curl ipfs://bafybeigagd5nmnn2iys2f3doro7ydrevyr2mzarwidgadawmamiteydbzi
```
With the IPFS protocol way of asking a file, cURL still needs to know the
gateway. curl essentially just rewrites the IPFS based URL to a gateway URL.
### IPFS_GATEWAY environment variable
If the `IPFS_GATEWAY` environment variable is found, its value is used as
gateway.
### Automatic gateway detection
When you provide no additional details to cURL then it:
1. First looks for the `IPFS_GATEWAY` environment variable and use that if it
is set.
2. Looks for the file: `~/.ipfs/gateway`. If it can find that file then it
means that you have a local gateway running and that file contains the URL
to your local gateway.
If cURL fails, you are presented with an error message and a link to this page
to the option most applicable to solving the issue.
### `--ipfs-gateway` argument
You can also provide a `--ipfs-gateway` argument to cURL. This overrules any
other gateway setting. curl does not fallback to the other options if the
provided gateway did not work.
## Gateway redirects
A gateway could redirect to another place. For example, `dweb.link` redirects
[path based](https://docs.ipfs.tech/how-to/address-ipfs-on-web/#path-gateway)
requests to [subdomain
based](https://docs.ipfs.tech/how-to/address-ipfs-on-web/#subdomain-gateway)
ones. A request using:
curl ipfs://bafybeigagd5nmnn2iys2f3doro7ydrevyr2mzarwidgadawmamiteydbzi --ipfs-gateway https://dweb.link
Which would be translated to:
https://dweb.link/ipfs/bafybeigagd5nmnn2iys2f3doro7ydrevyr2mzarwidgadawmamiteydbzi
redirects to:
https://bafybeigagd5nmnn2iys2f3doro7ydrevyr2mzarwidgadawmamiteydbzi.ipfs.dweb.link
If you trust this behavior from your gateway of choice then passing the `-L`
option follows the redirect.
## Error messages and hints
Depending on the arguments, cURL could present the user with an error.
### Gateway file and environment variable
cURL tried to look for the file: `~/.ipfs/gateway` but could not find it. It
also tried to look for the `IPFS_GATEWAY` environment variable but could not
find that either. This happens when no extra arguments are passed to cURL and
letting it try to figure it out [automatically](#automatic-gateway-detection).
Any IPFS implementation that has gateway support should expose its URL in
`~/.ipfs/gateway`. If you are already running a gateway, make sure it exposes
the file where cURL expects to find it.
Alternatively you could set the `IPFS_GATEWAY` environment variable or pass
the `--ipfs-gateway` flag to the cURL command.
### Malformed gateway URL
The command executed evaluates in an invalid URL. This could be anywhere in
the URL, but a likely point is a wrong gateway URL.
Inspect the URL set via the `IPFS_GATEWAY` environment variable or passed with
the `--ipfs-gateway` flag. Alternatively opt to go for the
[automatic](#automatic-gateway-detection) gateway detection.

https://github.com/curl/curl/issues/10457
2.5 Client cert handling with Issuer DN differs between backends
When the specified client certificate does not match any of the
server-specified DNs, the OpenSSL and GnuTLS backends behave differently.
The github discussion may contain a solution.
See https://github.com/curl/curl/issues/1411
2.7 Client cert (MTLS) issues with Schannel
See https://github.com/curl/curl/issues/3145
2.11 Schannel TLS 1.2 handshake bug in old Windows versions
In old versions of Windows such as 7 and 8.1 the Schannel TLS 1.2 handshake
implementation likely has a bug that can rarely cause the key exchange to
fail, resulting in error SEC_E_BUFFER_TOO_SMALL or SEC_E_MESSAGE_ALTERED.
https://github.com/curl/curl/issues/5488
2.13 CURLOPT_CERTINFO results in CURLE_OUT_OF_MEMORY with Schannel
https://github.com/curl/curl/issues/8741
2.14 mbedTLS and CURLE_AGAIN handling
https://github.com/curl/curl/issues/15801
3. Email protocols
3.1 IMAP SEARCH ALL truncated response
IMAP "SEARCH ALL" truncates output on large boxes. "A quick search of the
code reveals that pingpong.c contains some truncation code, at line 408, when
it deems the server response to be too large truncating it to 40 characters"
https://curl.se/bug/view.cgi?id=1366
3.2 No disconnect command
The disconnect commands (LOGOUT and QUIT) may not be sent by IMAP, POP3 and
SMTP if a failure occurs during the authentication phase of a connection.
3.4 AUTH PLAIN for SMTP is not working on all servers
Specifying "--login-options AUTH=PLAIN" on the command line does not seem to
work correctly.
See https://github.com/curl/curl/issues/4080
3.5 APOP authentication fails on POP3
See https://github.com/curl/curl/issues/10073
3.6 POP3 issue when reading small chunks
CURL_DBG_SOCK_RMAX=4 ./runtests.pl -v 982
See https://github.com/curl/curl/issues/12063
4. Command line
4.1 -T /dev/stdin may upload with an incorrect content length
-T stats the path to figure out its size in bytes to use it as Content-Length
if it is a regular file.
The problem with that is that, on BSDs and some other UNIXes (not Linux),
open(path) may not give you a file descriptor with a 0 offset from the start
of the file.
See https://github.com/curl/curl/issues/12177
4.2 -T - always uploads chunked
When the `<` shell operator is used. curl should realise that stdin is a
regular file in this case, and that it can do a non-chunked upload, like it
would do if you used -T file.
See https://github.com/curl/curl/issues/12171
5. Build and portability issues
5.1 OS400 port requires deprecated IBM library
curl for OS400 requires QADRT to build, which provides ASCII wrappers for
libc/POSIX functions in the ILE, but IBM no longer supports or even offers
this library to download.
See https://github.com/curl/curl/issues/5176
5.2 curl-config --libs contains private details
"curl-config --libs" include details set in LDFLAGS when configure is run
that might be needed only for building libcurl. Further, curl-config --cflags
suffers from the same effects with CFLAGS/CPPFLAGS.
5.3 LDFLAGS passed too late making libs linked incorrectly
Compiling latest curl on HP-UX and linking against a custom OpenSSL (which is
on the default loader/linker path), fails because the generated Makefile has
LDFLAGS passed on after LIBS.
See https://github.com/curl/curl/issues/14893
5.6 Cygwin: make install installs curl-config.1 twice
https://github.com/curl/curl/issues/8839
5.11 configure --with-gssapi with Heimdal is ignored on macOS
... unless you also pass --with-gssapi-libs
https://github.com/curl/curl/issues/3841
5.12 flaky CI builds
We run many CI builds for each commit and PR on github, and especially a
number of the Windows builds are flaky. This means that we rarely get all CI
builds go green and complete without errors. This is unfortunate as it makes
us sometimes miss actual build problems and it is surprising to newcomers to
the project who (rightfully) do not expect this.
See https://github.com/curl/curl/issues/6972
5.13 long paths are not fully supported on Windows
curl on Windows cannot access long paths (paths longer than 260 characters).
However, as a workaround, the Windows path prefix \\?\ which disables all
path interpretation may work to allow curl to access the path. For example:
\\?\c:\longpath.
See https://github.com/curl/curl/issues/8361
5.15 Unicode on Windows
Passing in a Unicode filename with -o:
https://github.com/curl/curl/issues/11461
Passing in Unicode character with -d:
https://github.com/curl/curl/issues/12231
Windows Unicode builds use homedir in current locale
The Windows Unicode builds of curl use the current locale, but expect Unicode
UTF-8 encoded paths for internal use such as open, access and stat. The
user's home directory is retrieved via curl_getenv in the current locale and
not as UTF-8 encoded Unicode.
See https://github.com/curl/curl/pull/7252 and
https://github.com/curl/curl/pull/7281
Cannot handle Unicode arguments in non-Unicode builds on Windows
If a URL or filename cannot be encoded using the user's current codepage then
it can only be encoded properly in the Unicode character set. Windows uses
UTF-16 encoding for Unicode and stores it in wide characters, however curl
and libcurl are not equipped for that at the moment except when built with
_UNICODE and UNICODE defined. Except for Cygwin, Windows cannot use UTF-8 as
a locale.
https://curl.se/bug/?i=345
https://curl.se/bug/?i=731
https://curl.se/bug/?i=3747
NTLM authentication and Unicode
NTLM authentication involving Unicode username or password only works
properly if built with UNICODE defined together with the Schannel backend.
The original problem was mentioned in:
https://curl.se/mail/lib-2009-10/0024.html
https://curl.se/bug/view.cgi?id=896
The Schannel version verified to work as mentioned in
https://curl.se/mail/lib-2012-07/0073.html
6. Authentication
6.2 MIT Kerberos for Windows build
libcurl fails to build with MIT Kerberos for Windows (KfW) due to KfW's
library header files exporting symbols/macros that should be kept private to
the KfW library. See ticket #5601 at https://krbdev.mit.edu/rt/
6.3 NTLM in system context uses wrong name
NTLM authentication using SSPI (on Windows) when (lib)curl is running in
"system context" makes it use wrong(?) username - at least when compared to
what winhttp does. See https://curl.se/bug/view.cgi?id=535
6.5 NTLM does not support password with Unicode 'SECTION SIGN' character
https://en.wikipedia.org/wiki/Section_sign
https://codepoints.net/U+00A7 SECTION SIGN
https://github.com/curl/curl/issues/2120
6.6 libcurl can fail to try alternatives with --proxy-any
When connecting via a proxy using --proxy-any, a failure to establish an
authentication causes libcurl to abort trying other options if the failed
method has a higher preference than the alternatives. As an example,
--proxy-any against a proxy which advertise Negotiate and NTLM, but which
fails to set up Kerberos authentication does not proceed to try
authentication using NTLM.
https://github.com/curl/curl/issues/876
6.7 Do not clear digest for single realm
https://github.com/curl/curl/issues/3267
6.8 Heimdal memory leaks
Running test 2077 and 2078 with curl built to do GSS with Heimdal causes
valgrind errors (memory leak).
https://github.com/curl/curl/issues/14446
6.9 SHA-256 digest not supported in Windows SSPI builds
Windows builds of curl that have SSPI enabled use the native Windows API calls
to create authentication strings. The call to InitializeSecurityContext fails
with SEC_E_QOP_NOT_SUPPORTED which causes curl to fail with CURLE_AUTH_ERROR.
Microsoft does not document supported digest algorithms and that SEC_E error
code is not a documented error for InitializeSecurityContext (digest).
https://github.com/curl/curl/issues/6302
6.10 curl never completes Negotiate over HTTP
Apparently it is not working correctly...?
See https://github.com/curl/curl/issues/5235
6.11 Negotiate on Windows fails
When using --negotiate (or NTLM) with curl on Windows, SSL/TLS handshake
fails despite having a valid kerberos ticket cached. Works without any issue
in Unix/Linux.
https://github.com/curl/curl/issues/5881
6.13 Negotiate authentication against Hadoop HDFS
https://github.com/curl/curl/issues/8264
7. FTP
7.4 FTP with ACCT
When doing an operation over FTP that requires the ACCT command (but not when
logging in), the operation fails since libcurl does not detect this and thus
fails to issue the correct command: https://curl.se/bug/view.cgi?id=635
7.12 FTPS server compatibility on Windows with Schannel
FTPS is not widely used with the Schannel TLS backend and so there may be
more bugs compared to other TLS backends such as OpenSSL. In the past users
have reported hanging and failed connections. It is likely some changes to
curl since then fixed the issues. None of the reported issues can be
reproduced any longer.
If you encounter an issue connecting to your server via FTPS with the latest
curl and Schannel then please search for open issues or file a new issue.
9. SFTP and SCP
9.1 SFTP does not do CURLOPT_POSTQUOTE correct
When libcurl sends CURLOPT_POSTQUOTE commands when connected to an SFTP
server using the multi interface, the commands are not being sent correctly
and instead the connection is "cancelled" (the operation is considered done)
prematurely. There is a half-baked (busy-looping) patch provided in the bug
report but it cannot be accepted as-is. See
https://curl.se/bug/view.cgi?id=748
9.2 wolfssh: publickey auth does not work
When building curl to use the wolfSSH backend for SFTP, the publickey
authentication does not work. This is simply functionality not written for curl
yet, the necessary API for make this work is provided by wolfSSH.
See https://github.com/curl/curl/issues/4820
9.3 Remote recursive folder creation with SFTP
On this servers, the curl fails to create directories on the remote server
even when the CURLOPT_FTP_CREATE_MISSING_DIRS option is set.
See https://github.com/curl/curl/issues/5204
9.4 libssh blocking and infinite loop problem
In the SSH_SFTP_INIT state for libssh, the ssh session working mode is set to
blocking mode. If the network is suddenly disconnected during sftp
transmission, curl is stuck, even if curl is configured with a timeout.
https://github.com/curl/curl/issues/8632
9.5 Cygwin: "WARNING: UNPROTECTED PRIVATE KEY FILE!"
Running SCP and SFTP tests on Cygwin makes this warning message appear.
https://github.com/curl/curl/issues/11244
9.6 wolfssh: all tests fail
Something fundamental stops them all from working properly.
https://github.com/curl/curl/issues/16794
10. Connection
10.1 --interface with link-scoped IPv6 address
When you give the `--interface` option telling curl to use a specific
interface for its outgoing traffic in combination with an IPv6 address in the
URL that uses a link-local scope, curl might pick the wrong address from the
named interface and the subsequent transfer fails.
Example command line:
curl --interface eth0 'http://[fe80:928d:xxff:fexx:xxxx]/'
The fact that the given IP address is link-scoped should probably be used as
input to somehow make curl make a better choice for this.
https://github.com/curl/curl/issues/14782
10.2 Does not acknowledge getaddrinfo sorting policy
Even if a user edits /etc/gai.conf to prefer IPv4, curl still prefers and
tries IPv6 addresses first.
https://github.com/curl/curl/issues/16718
11. Internals
11.1 gssapi library name + version is missing in curl_version_info()
The struct needs to be expanded and code added to store this info.
See https://github.com/curl/curl/issues/13492
11.2 error buffer not set if connection to multiple addresses fails
If you ask libcurl to resolve a hostname like example.com to IPv6 addresses
when you only have IPv4 connectivity. libcurl fails with
CURLE_COULDNT_CONNECT, but the error buffer set by CURLOPT_ERRORBUFFER
remains empty. Issue: https://github.com/curl/curl/issues/544
11.4 HTTP test server 'connection-monitor' problems
The 'connection-monitor' feature of the sws HTTP test server does not work
properly if some tests are run in unexpected order. Like 1509 and then 1525.
See https://github.com/curl/curl/issues/868
11.5 Connection information when using TCP Fast Open
CURLINFO_LOCAL_PORT (and possibly a few other) fails when TCP Fast Open is
enabled.
See https://github.com/curl/curl/issues/1332 and
https://github.com/curl/curl/issues/4296
11.6 test cases sometimes timeout
Occasionally, one of the tests timeouts. Inexplicably.
See https://github.com/curl/curl/issues/13350
11.7 CURLOPT_CONNECT_TO does not work for HTTPS proxy
It is unclear if the same option should even cover the proxy connection or if
if requires a separate option.
See https://github.com/curl/curl/issues/14481
11.8 WinIDN test failures
Test 165 disabled when built with WinIDN.
11.9 setting a disabled option should return CURLE_NOT_BUILT_IN
When curl has been built with specific features or protocols disabled,
setting such options with curl_easy_setopt() should rather return
CURLE_NOT_BUILT_IN instead of CURLE_UNKNOWN_OPTION to signal the difference
to the application
See https://github.com/curl/curl/issues/15472
12. LDAP
12.1 OpenLDAP hangs after returning results
By configuration defaults, OpenLDAP automatically chase referrals on
secondary socket descriptors. The OpenLDAP backend is asynchronous and thus
should monitor all socket descriptors involved. Currently, these secondary
descriptors are not monitored, causing OpenLDAP library to never receive
data from them.
As a temporary workaround, disable referrals chasing by configuration.
The fix is not easy: proper automatic referrals chasing requires a
synchronous bind callback and monitoring an arbitrary number of socket
descriptors for a single easy handle (currently limited to 5).
Generic LDAP is synchronous: OK.
See https://github.com/curl/curl/issues/622 and
https://curl.se/mail/lib-2016-01/0101.html
12.2 LDAP on Windows does authentication wrong?
https://github.com/curl/curl/issues/3116
12.3 LDAP on Windows does not work
A simple curl command line getting "ldap://ldap.forumsys.com" returns an
error that says "no memory" !
https://github.com/curl/curl/issues/4261
12.4 LDAPS requests to ActiveDirectory server hang
https://github.com/curl/curl/issues/9580
13. TCP/IP
13.2 Trying local ports fails on Windows
This makes '--local-port [range]' to not work since curl cannot properly
detect if a port is already in use, so it tries the first port, uses that and
then subsequently fails anyway if that was actually in use.
https://github.com/curl/curl/issues/8112
15. CMake
15.1 cmake outputs: no version information available
Something in the SONAME generation seems to be wrong in the cmake build.
https://github.com/curl/curl/issues/11158
15.6 uses -lpthread instead of Threads::Threads
See https://github.com/curl/curl/issues/6166
15.7 generated .pc file contains strange entries
The Libs.private field of the generated .pc file contains -lgcc -lgcc_s -lc
-lgcc -lgcc_s
See https://github.com/curl/curl/issues/6167
15.13 CMake build with MIT Kerberos does not work
Minimum CMake version was bumped in curl 7.71.0 (#5358) Since CMake 3.2
try_compile started respecting the CMAKE_EXE_FLAGS. The code dealing with
MIT Kerberos detection sets few variables to potentially weird mix of space,
and ;-separated flags. It had to blow up at some point. All the CMake checks
that involve compilation are doomed from that point, the configured tree
cannot be built.
https://github.com/curl/curl/issues/6904
16. aws-sigv4
16.2 aws-sigv4 does not handle multipart/form-data correctly
https://github.com/curl/curl/issues/13351
17. HTTP/2
17.1 HTTP/2 prior knowledge over proxy
https://github.com/curl/curl/issues/12641
17.2 HTTP/2 frames while in the connection pool kill reuse
If the server sends HTTP/2 frames (like for example an HTTP/2 PING frame) to
curl while the connection is held in curl's connection pool, the socket is
found readable when considered for reuse and that makes curl think it is dead
and then it is closed and a new connection gets created instead.
This is *best* fixed by adding monitoring to connections while they are kept
in the pool so that pings can be responded to appropriately.
17.3 ENHANCE_YOUR_CALM causes infinite retries
Infinite retries with 2 parallel requests on one connection receiving GOAWAY
with ENHANCE_YOUR_CALM error code.
See https://github.com/curl/curl/issues/5119
17.4 HTTP/2 + TLS spends a lot of time in recv
It has been observed that by making the speed limit less accurate we could
improve this performance. (by reverting
https://github.com/curl/curl/commit/db5c9f4f9e0779b49624752b135281a0717b277b)
Can we find a golden middle ground?
See https://curl.se/mail/lib-2024-05/0026.html and
https://github.com/curl/curl/issues/13416
18. HTTP/3
18.1 connection migration does not work
https://github.com/curl/curl/issues/7695
18.2 quiche: QUIC connection is draining
The transfer ends with error "QUIC connection is draining".
https://github.com/curl/curl/issues/12037
19. RTSP
19.1 Some methods do not support response bodies
The RTSP implementation is written to assume that a number of RTSP methods
always get responses without bodies, even though there seems to be no
indication in the RFC that this is always the case.
https://github.com/curl/curl/issues/12414

# Mail etiquette
## About the lists
### Mailing Lists
The mailing lists we have are all listed and described on the [curl
website](https://curl.se/mail/).
Each mailing list is targeted to a specific set of users and subjects, please
use the one or the ones that suit you the most.
Each mailing list has hundreds up to thousands of readers, meaning that each
mail sent is received and read by a large number of people. People from
various cultures, regions, religions and continents.
### Netiquette
Netiquette is a common term for how to behave on the Internet. Of course, in
each particular group and subculture there are differences in what is
acceptable and what is considered good manners.
This document outlines what we in the curl project consider to be good
etiquette, and primarily this focus on how to behave on and how to use our
mailing lists.
### Do Not Mail a Single Individual
Many people send one question to one person. One person gets many mails, and
there is only one person who can give you a reply. The question may be
something that other people would also like to ask. These other people have no
way to read the reply, but to ask the one person the question. The one person
consequently gets overloaded with mail.
If you really want to contact an individual and perhaps pay for his or her
services, by all means go ahead, but if it is just another curl question, take
it to a suitable list instead.
### Subscription Required
All curl mailing lists require that you are subscribed to allow a mail to go
through to all the subscribers.
If you post without being subscribed (or from a different mail address than
the one you are subscribed with), your mail is simply silently discarded. You
have to subscribe first, then post.
The reason for this unfortunate and strict subscription policy is of course to
stop spam from pestering the lists.
### Moderation of new posters
Several of the curl mailing lists automatically make all posts from new
subscribers be moderated. After you have subscribed and sent your first mail
to a list, that mail is not let through to the list until a mailing list
administrator has verified that it is OK and permits it to get posted.
Once a first post has been made that proves the sender is actually talking
about curl-related subjects, the moderation "flag" is switched off and future
posts go through without being moderated.
The reason for this moderation policy is that we do suffer from spammers who
actually subscribe and send spam to our lists.
### Handling trolls and spam
Despite our good intentions and hard work to keep spam off the lists and to
maintain a friendly and positive atmosphere, there are times when spam and or
trolls get through.
Troll - "someone who posts inflammatory, extraneous, or off-topic messages in
an online community"
Spam - "use of electronic messaging systems to send unsolicited bulk messages"
No matter what, we NEVER EVER respond to trolls or spammers on the list. If
you believe the list admin should do something in particular, contact them
off-list. The subject is taken care of as much as possible to prevent repeated
offenses, but responding on the list to such messages never leads to anything
good and only puts the light even more on the offender: which was the entire
purpose of it getting sent to the list in the first place.
Do not feed the trolls.
### How to unsubscribe
You can unsubscribe the same way you subscribed in the first place. You go to
the page for the particular mailing list you are subscribed to and you enter
your email address and password and press the unsubscribe button.
Also, the instructions to unsubscribe are included in the headers of every
mail that is sent out to all curl related mailing lists and there is a footer
in each mail that links to the "admin" page on which you can unsubscribe and
change other options.
You NEVER EVER email the mailing list requesting someone else to take you off
the list.
### I posted, now what?
If you are not subscribed with the same email address that you used to send
the email, your post is silently discarded.
If you posted for the first time to the mailing list, you first need to wait
for an administrator to allow your email to go through (moderated). This
normally happens quickly but in case we are asleep, you may have to wait a few
hours.
Once your email goes through it is sent out to several hundred or even
thousands of recipients. Your email may cover an area that not that many
people know about or are interested in. Or possibly the person who knows about
it is on vacation or under a heavy work load right now. You may have to wait
for a response and you should not expect to get a response at all. Ideally,
you get an answer within a couple of days.
You do yourself and all of us a service when you include as many details as
possible already in your first email. Mention your operating system and
environment. Tell us which curl version you are using and tell us what you
did, what happened and what you expected would happen. Preferably, show us
what you did with details enough to allow others to help point out the problem
or repeat the steps in their locations.
Failing to include details only delays responses and make people respond and
ask for more details and you have to send follow-up emails that include them.
Expect the responses to primarily help YOU debug the issue, or ask YOU
questions that can lead you or others towards a solution or explanation to
whatever you experience.
If you are a repeat offender to the guidelines outlined in this document,
chances are that people ignore you and your chances to get responses in the
future greatly diminish.
### Your emails are public
Your email, its contents and all its headers and the details in those headers
are received by every subscriber of the mailing list that you send your email
to.
Your email as sent to a curl mailing list ends up in mail archives, on the
curl website and elsewhere, for others to see and read. Today and in the
future. In addition to the archives, the mail is sent out to thousands of
individuals. There is no way to undo a sent email.
When sending emails to a curl mailing list, do not include sensitive
information such as usernames and passwords; use fake ones, temporary ones or
just remove them completely from the mail. Note that this includes base64
encoded HTTP Basic auth headers.
This public nature of the curl mailing lists makes automatically inserted mail
footers about mails being "private" or "only meant for the recipient" or
similar even more silly than usual. Because they are absolutely not private
when sent to a public mailing list.
## Sending mail
### Reply or New Mail
Please do not reply to an existing message as a short-cut to post a message to
the lists.
Many mail programs and web archivers use information within mails to keep them
together as "threads", as collections of posts that discuss a certain subject.
If you do not intend to reply on the same or similar subject, do not just hit
reply on an existing mail and change the subject, create a new mail.
### Reply to the List
When replying to a message from the list, make sure that you do "group reply"
or "reply to all", and not just reply to the author of the single mail you
reply to.
We are actively discouraging replying to the single person by setting the
correct field in outgoing mails back asking for replies to get sent to the
mailing list address, making it harder for people to reply to the author only
by mistake.
### Use a Sensible Subject
Please use a subject of the mail that makes sense and that is related to the
contents of your mail. It makes it a lot easier to find your mail afterwards
and it makes it easier to track mail threads and topics.
### Do Not Top-Post
If you reply to a message, do not use top-posting. Top-posting is when you
write the new text at the top of a mail and you insert the previous quoted
mail conversation below. It forces users to read the mail in a backwards order
to properly understand it.
This is why top posting is so bad (in top posting order):
A: Because it messes up the order in which people normally read text.
Q: Why is top-posting such a bad thing?
A: Top-posting.
Q: What is the most annoying thing in email?
Apart from the screwed up read order (especially when mixed together in a
thread when someone responds using the mandated bottom-posting style), it also
makes it impossible to quote only parts of the original mail.
When you reply to a mail. You let the mail client insert the previous mail
quoted. Then you put the cursor on the first line of the mail and you move
down through the mail, deleting all parts of the quotes that do not add
context for your comments. When you want to add a comment you do so, inline,
right after the quotes that relate to your comment. Then you continue
downwards again.
When most of the quotes have been removed and you have added your own words,
you are done.
### HTML is not for mails
Please switch off those HTML encoded messages. You can mail all those funny
mails to your friends. We speak plain text mails.
### Quoting
Quote as little as possible. Just enough to provide the context you cannot
eave out. A lengthy description can be found
[here](https://www.netmeister.org/news/learn2quote.html).
### Digest
We allow subscribers to subscribe to the "digest" version of the mailing
lists. A digest is a collection of mails lumped together in one single mail.
Should you decide to reply to a mail sent out as a digest, there are two
things you MUST consider if you really, really cannot subscribe normally
instead:
Cut off all mails and chatter that is not related to the mail you want to
reply to.
Change the subject name to something sensible and related to the subject,
preferably even the actual subject of the single mail you wanted to reply to
### Please Tell Us How You Solved The Problem
Many people mail questions to the list, people spend some of their time and
make an effort in providing good answers to these questions.
If you are the one who asks, please consider responding once more in case one
of the hints was what solved your problems. The guys who write answers feel
good to know that they provided a good answer and that you fixed the problem.
Far too often, the person who asked the question is never heard from again,
and we never get to know if they are gone because the problem was solved or
perhaps because the problem was unsolvable.
Getting the solution posted also helps other users that experience the same
problem(s). They get to see (possibly in the web archives) that the suggested
fixes actually have helped at least one person.

curl release procedure - how to do a release
============================================
in the source code repo
-----------------------
- edit `RELEASE-NOTES` to be accurate
- update `docs/THANKS`
- update the "past releases" section in `docs/VERSIONS.md`
- make sure all relevant changes are committed on the master branch
- tag the git repo in this style: `git tag -a curl-7_34_0`. -a annotates the
tag and we use underscores instead of dots in the version number. Make sure
the tag is GPG signed (using -s).
- run `./scripts/dmaketgz 7.34.0` to build the release tarballs.
- push the git commits and the new tag
- GPG sign the 4 tarballs as `maketgz` suggests
- upload the 8 resulting files to the primary download directory
in the curl-www repo
--------------------
- edit `Makefile` (version number and date),
- edit `_newslog.html` (announce the new release) and
- edit `_changes.html` (insert changes+bugfixes from RELEASE-NOTES)
- commit all local changes
- tag the repo with the same name as used for the source repo.
- make sure all relevant changes are committed and pushed on the master branch
(the website then updates its contents automatically)
on GitHub
---------
- edit the newly made release tag so that it is listed as the latest release
inform
------
- send an email to curl-users, curl-announce and curl-library. Insert the
RELEASE-NOTES into the mail.
- if there are any advisories associated with the release, send each markdown
file to the above lists as well as to `oss-security@lists.openwall.com`
(unless the problem is unique to the non-open operating systems)
celebrate
---------
- suitable beverage intake is encouraged for the festivities
curl release scheduling
=======================
Release Cycle
-------------
We normally do releases every 8 weeks on Wednesdays. If important problems
arise, we can insert releases outside the schedule or we can move the release
date.
Each 8 week (56 days) release cycle is divided into three distinct periods:
- During the first 10 calendar days after a release, we are in "cool down". We
do not merge features but only bug-fixes. If a regression is reported, we
might do a follow-up patch release.
- During the following 3 weeks (21 days) there is a feature window: we allow
new features and changes to curl and libcurl. If we accept any such changes,
we bump the minor number used for the next release.
- During the next 25 days we are in feature freeze. We do not merge any
features or changes, and we only focus on fixing bugs and polishing things
to make the pending release a solid one.
If a future release date happens to end up on a "bad date", like in the middle
of common public holidays or when the lead release manager is unavailable, the
release date can be moved forwards or backwards a full week. This is then
advertised well in advance.
Release Candidates
------------------
We ship release candidate tarballs on three occasions in preparation for the
pending release:
- Release candidate one (**rc1**) ships the same Saturday the feature freeze
starts. Twenty-five days before the release. Tagged like `rc-7_34_0-1`.
- Release candidate two (**rc2**) ships nine days later, sixteen days before
the release. On a Monday. Tagged like `rc-7_34_0-2`.
- Release candidate tree (**rc3**) ships nine days later, seven days before
the release. On a Wednesday. Tagged like `rc-7_34_0-3`.
Release candidate tarballs are ephemeral and each such tarball is only kept
around for a few weeks. They are provided on their dedicated webpage at:
https://curl.se/rc/
The git tags for release candidate are temporary and remain set only for a
limited period of time.
**Do not use release candidates in production**. They are work in progress.
Use them for testing and verification only. Use actual releases in production.
Critical problems
-----------------
We can break the release cycle and do a patch release at any point if a
critical enough problem is reported. There is no exact definition of how to
assess such criticality, but if an issue is highly disturbing or has a
security impact on a large enough share of the user population it might
qualify.
If you think an issue qualifies, bring it to the curl-library mailing list and
push for it.
Coming dates
------------
Based on the description above, here are some planned future release dates:
- May 28, 2025
- July 16, 2025
- September 10, 2025
- November 5, 2025
- January 7, 2026
- March 4, 2026
- April 29, 2026

# Rustls
[Rustls is a TLS backend written in Rust](https://docs.rs/rustls/). curl can
be built to use it as an alternative to OpenSSL or other TLS backends. We use
the [rustls-ffi C bindings](https://github.com/rustls/rustls-ffi/). This
version of curl is compatible with `rustls-ffi` v0.15.x.
## Getting rustls-ffi
To build `curl` with `rustls` support you need to have `rustls-ffi` available first.
There are three options for this:
1. Install it from your package manager, if available.
2. Download pre-built binaries.
3. Build it from source.
### Installing rustls-ffi from a package manager
See the [rustls-ffi README] for packaging status. Availability and details for installation
differ between distributions.
Once installed, build `curl` using `--with-rustls`.
% git clone https://github.com/curl/curl

### Downloading pre-built rustls-ffi binaries
Pre-built binaries are available on the [releases page] on GitHub for releases since 0.15.0.
Download the appropriate archive for your platform and extract it to a directory of your choice
(e.g. `${HOME}/rustls-ffi-built`).
Once downloaded, build `curl` using `--with-rustls` and the path to the extracted binaries.
% git clone https://github.com/curl/curl
% cd curl
% autoreconf -fi
% ./configure --with-rustls=${HOME}/rustls-ffi-built
% make
[releases page]: https://github.com/rustls/rustls-ffi/releases
### Building rustls-ffi from source
Building `rustls-ffi` from source requires both a rust compiler, and the [cargo-c] cargo plugin.
To install a Rust compiler, use [rustup] or your package manager to install
the **1.73+** or newer toolchain.
To install `cargo-c`, use your [package manager][cargo-c pkg], download
[a pre-built archive][cargo-c prebuilt], or build it from source with `cargo install cargo-c`.
Next, check out, build, and install the appropriate version of `rustls-ffi` using `cargo`:
% git clone https://github.com/rustls/rustls-ffi -b v0.15.0
% cd rustls-ffi
% cargo capi install --release --prefix=${HOME}/rustls-ffi-built
Now configure and build `curl` using `--with-rustls`:
% git clone https://github.com/curl/curl
% cd curl
% autoreconf -fi
% ./configure --with-rustls=${HOME}/rustls-ffi-built
% make
See the [rustls-ffi README][cryptography provider] for more information on cryptography providers and
their build/platform requirements.

# Anatomy of a curl security advisory
As described in the [Security Process](https://curl.se/dev/secprocess.html)
document, when a security vulnerability has been reported to the project and
confirmed, we author an advisory document for the issue. It should ideally
be written in cooperation with the reporter to make sure all the angles and
details of the problem are gathered and described correctly and succinctly.
## New document
A security advisory for curl is created in the `docs/` folder in the
[curl-www](https://github.com/curl/curl-www) repository. It should be named
`$CVEID.md` where `$CVEID` is the full CVE Id that has been registered for the
flaw. Like `CVE-2016-0755`. The `.md` extension of course means that the
document is written using markdown.
The standard way to go about this is to first write the `VULNERABILITY`
section for the document, so that there is description of the flaw available,
then paste this description into the CVE Id request.
### `vuln.pm`
The new issue should be entered at the top of the list in the file `vuln.pm`
in the same directory. It holds a large array with all published curl
vulnerabilities. All fields should be filled in accordingly, separated by a
pipe character (`|`).
The eleven fields for each CVE in `vuln.pm` are, in order:
HTML page name, first vulnerable version, last vulnerable version, name of
the issue, CVE Id, announce date (`YYYYMMDD`), report to the project date
(`YYYYMMDD`), CWE, awarded reward amount (USD), area (single word), C-issue
(`-` if not a C issue at all, `OVERFLOW` , `OVERREAD`, `DOUBLE_FREE`,
`USE_AFTER_FREE`, `NULL_MISTAKE`, `UNINIT`)
### `Makefile`
The new CVE webpage filename needs to be added in the `Makefile`'s `CVELIST`
macro.
When the markdown is in place and the `Makefile` and `vuln.pm` are updated,
all other files and metadata for all curl advisories and versions get
generated automatically using those files.
## Document format
The easy way is to start with a recent previously published advisory and just
blank out old texts and save it using a new name. Save the subtitles and
general layout.
Some details and metadata are extracted from this document so it is important
to stick to the existing format.
The first list must be the title of the issue.
### VULNERABILITY
The first subtitle should be `VULNERABILITY`. That should then include a
through and detailed description of the flaw. Including how it can be
triggered and maybe something about what might happen if triggered or
exploited.
### INFO
The next section is `INFO` which adds meta data information about the flaw. It
specifically mentions the official CVE Id for the issue and it must list the
CWE Id, starting on its own line. We write CWE identifiers in advisories with
the full (official) explanation on the right side of a colon. Like this:
`CWE-305: Authentication Bypass by Primary Weakness`
### AFFECTED VERSIONS
The third section first lists what versions that are affected, then adds
clarity by stressing what versions that are *not* affected. A third line adds
information about which specific git commit that introduced the vulnerability.
The `Introduced-in` commit should be a full URL that displays the commit, but
should work as a stand-alone commit hash if everything up to the last slash is
cut out.
An example using the correct syntax:
~~~
- Affected versions: curl 7.16.1 to and including 7.88.1
- Not affected versions: curl < 7.16.1 and curl >= 8.0.0
- Introduced-in: https://github.com/curl/curl/commit/2147284cad
~~~
### THE SOLUTION
This section describes and discusses the fix. The only mandatory information
here is the link to the git commit that fixes the problem.
The `Fixed-in` value should be a full URL that displays the commit, but should
work as a stand-alone commit hash if everything up to the last slash is cut
out.
Example:
`- Fixed-in: https://github.com/curl/curl/commit/af369db4d3833272b8ed`
### RECOMMENDATIONS
This section lists the recommended actions for the users in a top to bottom
priority order and should ideally contain three items but no less than two.
The top two are almost always `upgrade curl to version XXX` and `apply the
patch to your local version`.
### TIMELINE
Detail when this report was received in the project. When package distributors
were notified (via the distros mailing list or similar)
When the advisory and fixed version are released.
### CREDITS
Mention the reporter and patch author at least, then everyone else involved
you think deserves a mention.
If you want to mention more than one name, separate the names with comma
(`,`).

- Reported-by: Full Name
- Patched-by: Full Name

# curl sponsors
A sponsor is someone who donates money or resources to the curl project for no
specific service in return.
curl accepts donations via [GitHub sponsors](https://github.com/sponsors/curl)
and [Open Collective](https://opencollective.com/curl).
An even better way to contribute to the project might be to pay an engineer or
two to spend work hours on curl related tasks.
We promise to use donated funds for things and activities that we believe are
beneficial for the project and its development. That includes but is not
limited to bug-bounties, developer conferences, infrastructure, development,
services and hardware.
Recurring donations above a certain amount of money puts the sponsor at a
named sponsor level: **Silver**, **Gold**, **Platinum** or **Top**.
Sponsors on a named level can provide their logo image and preferred URL and
get recognition on the curl website's [sponsor
page](https://curl.se/sponsors.html), assuming they meet the project's
standards and requirements.
- **Silver Sponsor** at least 100 USD/month
- **Gold Sponsor** at least 500 USD/month
- **Platinum Sponsor** at least 1000 USD/month
- **Top Sponsor** outstanding extra valuable help
## Sponsor requirements
A named level sponsor is entitled a logo and link on the curl website assuming
the company, brand and link are not deemed unsuitable. The curl team reserves
the right to make that decision at its own discretion.
Sponsors may be denied a website presence for example if involved with drugs,
gambling, pornography, social media manipulation etc.
## Past Sponsors
Sponsors that stop paying are considered *Past Sponsors* and are not displayed
on the sponsor page anymore. We thank you for your contributions.
## Donations
Please note that sponsorship and donations are exactly that: donations to the
curl project. They are used to help and further the project as the project
leadership deems best. No goods or services are expected or promised in
return. Requests for refunds for such purposes are rejected.

# SSL problems
First, let's establish that we often refer to TLS and SSL interchangeably as
SSL here. The current protocol is called TLS, it was called SSL a long time
ago.
There are several known reasons why a connection that involves SSL might
fail. This is a document that attempts to detail the most common ones and
how to mitigate them.
## CA certs
CA certs are used to digitally verify the server's certificate. You need a
"ca bundle" for this. See lots of more details on this in the `SSLCERTS`
document.
## CA bundle missing intermediate certificates
When using said CA bundle to verify a server cert, you may experience
problems if your CA store does not contain the certificates for the
intermediates if the server does not provide them.
The TLS protocol mandates that the intermediate certificates are sent in the
handshake, but as browsers have ways to survive or work around such
omissions, missing intermediates in TLS handshakes still happen that browser
users do not notice.
Browsers work around this problem in two ways: they cache intermediate
certificates from previous transfers and some implement the TLS "AIA"
extension that lets the client explicitly download such certificates on
demand.
## Protocol version
Some broken servers fail to support the protocol negotiation properly that
SSL servers are supposed to handle. This may cause the connection to fail
completely. Sometimes you may need to explicitly select an SSL version to
use when connecting to make the connection succeed.
An additional complication can be that modern SSL libraries sometimes are
built with support for older SSL and TLS versions disabled.
All versions of SSL and the TLS versions before 1.2 are considered insecure
and should be avoided. Use TLS 1.2 or later.
## Ciphers
Clients give servers a list of ciphers to select from. If the list does not
include any ciphers the server wants/can use, the connection handshake
fails.
curl has recently disabled the user of a whole bunch of seriously insecure
ciphers from its default set (slightly depending on SSL backend in use).
You may have to explicitly provide an alternative list of ciphers for curl
to use to allow the server to use a weak cipher for you.
Note that these weak ciphers are identified as flawed. For example, this
includes symmetric ciphers with less than 128 bit keys and RC4.
Schannel in Windows XP is not able to connect to servers that no longer
support the legacy handshakes and algorithms used by those versions, so we
advise against building curl to use Schannel on really old Windows versions.
Reference: [Prohibiting RC4 Cipher
Suites](https://datatracker.ietf.org/doc/html/draft-popov-tls-prohibiting-rc4-01)
## Allow BEAST
BEAST is the name of a TLS 1.0 attack that surfaced 2011. When adding means
to mitigate this attack, it turned out that some broken servers out there in
the wild did not work properly with the BEAST mitigation in place.
To make such broken servers work, the --ssl-allow-beast option was
introduced. Exactly as it sounds, it re-introduces the BEAST vulnerability
but on the other hand it allows curl to connect to that kind of strange
servers.
## Disabling certificate revocation checks
Some SSL backends may do certificate revocation checks (CRL, OCSP, etc)
depending on the OS or build configuration. The --ssl-no-revoke option was
introduced in 7.44.0 to disable revocation checking but currently is only
supported for Schannel (the native Windows SSL library), with an exception
in the case of Windows' Untrusted Publishers block list which it seems cannot
be bypassed. This option may have broader support to accommodate other SSL
backends in the future.

# TLS Certificate Verification
## Native vs file based
If curl was built with Schannel support, then curl uses the system native CA
store for verification. All other TLS libraries use a file based CA store by
default.
## Verification
Every trusted server certificate is digitally signed by a Certificate
Authority, a CA.
In your local CA store you have a collection of certificates from *trusted*
certificate authorities that TLS clients like curl use to verify servers.
curl does certificate verification by default. This is done by verifying the
signature and making sure the certificate was crafted for the server name
provided in the URL.
If you communicate with HTTPS, FTPS or other TLS-using servers using
certificates signed by a CA whose certificate is present in the store, you can
be sure that the remote server really is the one it claims to be.
If the remote server uses a self-signed certificate, if you do not install a
CA cert store, if the server uses a certificate signed by a CA that is not
included in the store you use or if the remote host is an impostor
impersonating your favorite site, the certificate check fails and reports an
error.
If you think it wrongly failed the verification, consider one of the following
sections.
### Skip verification
Tell curl to *not* verify the peer with `-k`/`--insecure`.
We **strongly** recommend this is avoided and that even if you end up doing
this for experimentation or development, **never** skip verification in
production.
### Use a custom CA store
Get a CA certificate that can verify the remote server and use the proper
option to point out this CA cert for verification when connecting - for this
specific transfer only.
With the curl command line tool: `--cacert [file]`
If you use the curl command line tool without a native CA store, then you can
specify your own CA cert file by setting the environment variable
`CURL_CA_BUNDLE` to the path of your choice. `SSL_CERT_FILE` and `SSL_CERT_DIR`
are also supported.
If you are using the curl command line tool on Windows, curl searches for a CA
cert file named `curl-ca-bundle.crt` in these directories and in this order:
1. application's directory
2. current working directory
3. Windows System directory (e.g. C:\Windows\System32)
4. Windows Directory (e.g. C:\Windows)
5. all directories along %PATH%
curl 8.11.0 added a build-time option to disable this search behavior, and
another option to restrict search to the application's directory.
### Use the native store
In several environments, in particular on Windows, you can ask curl to use the
system's native CA store when verifying the certificate.
With the curl command line tool: `--ca-native`.
### Modify the CA store
Add the CA cert for your server to the existing default CA certificate store.
Usually you can figure out the path to the local CA store by looking at the
verbose output that `curl -v` shows when you connect to an HTTPS site.
### Change curl's default CA store
The default CA certificate store curl uses is set at build time. When you
build curl you can point out your preferred path.
### Extract CA cert from a server
curl -w %{certs} https://example.com > cacert.pem
The certificate has `BEGIN CERTIFICATE` and `END CERTIFICATE` markers.
### Get the Mozilla CA store
Download a version of the Firefox CA store converted to PEM format on the [CA
Extract](https://curl.se/docs/caextract.html) page. It always features the
latest Firefox bundle.
## Native CA store
If curl was built with Schannel or was instructed to use the native CA Store,
then curl uses the certificates that are built into the OS. These are the same
certificates that appear in the Internet Options control panel (under Windows)
or Keychain Access application (under macOS). Any custom security rules for
certificates are honored.
Schannel runs CRL checks on certificates unless peer verification is disabled.
## HTTPS proxy
curl can do HTTPS to the proxy separately from the connection to the server.
This TLS connection is handled and verified separately from the server
connection so instead of `--insecure` and `--cacert` to control the
certificate verification, you use `--proxy-insecure` and `--proxy-cacert`.
With these options, you make sure that the TLS connection and the trust of the
proxy can be kept totally separate from the TLS connection to the server.

# The Art Of Scripting HTTP Requests Using curl
## Background
This document assumes that you are familiar with HTML and general networking.
The increasing amount of applications moving to the web has made "HTTP
Scripting" more frequently requested and wanted. To be able to automatically
extract information from the web, to fake users, to post or upload data to
web servers are all important tasks today.
curl is a command line tool for doing all sorts of URL manipulations and
transfers, but this particular document focuses on how to use it when doing
HTTP requests for fun and profit. This documents assumes that you know how to
invoke `curl --help` or `curl --manual` to get basic information about it.
curl is not written to do everything for you. It makes the requests, it gets
the data, it sends data and it retrieves the information. You probably need
to glue everything together using some kind of script language or repeated
manual invokes.
## The HTTP Protocol
HTTP is the protocol used to fetch data from web servers. It is a simple
protocol that is built upon TCP/IP. The protocol also allows information to
get sent to the server from the client using a few different methods, as is
shown here.
HTTP is plain ASCII text lines being sent by the client to a server to
request a particular action, and then the server replies a few text lines
before the actual requested content is sent to the client.
The client, curl, sends an HTTP request. The request contains a method (like
GET, POST, HEAD etc), a number of request headers and sometimes a request
body. The HTTP server responds with a status line (indicating if things went
well), response headers and most often also a response body. The "body" part
is the plain data you requested, like the actual HTML or the image etc.
## See the Protocol
Using curl's option [`--verbose`](https://curl.se/docs/manpage.html#-v) (`-v`
as a short option) displays what kind of commands curl sends to the server,
as well as a few other informational texts.
`--verbose` is the single most useful option when it comes to debug or even
understand the curl<->server interaction.
Sometimes even `--verbose` is not enough. Then
[`--trace`](https://curl.se/docs/manpage.html#-trace) and
[`--trace-ascii`](https://curl.se/docs/manpage.html#--trace-ascii)
offer even more details as they show **everything** curl sends and
receives. Use it like this:
curl --trace-ascii debugdump.txt http://www.example.com/
## See the Timing
Many times you may wonder what exactly is taking all the time, or you just
want to know the amount of milliseconds between two points in a transfer. For
those, and other similar situations, the
[`--trace-time`](https://curl.se/docs/manpage.html#--trace-time) option is
what you need. It prepends the time to each trace output line:
curl --trace-ascii d.txt --trace-time http://example.com/
## See which Transfer
When doing parallel transfers, it is relevant to see which transfer is doing
what. When response headers are received (and logged) you need to know which
transfer these are for.
[`--trace-ids`](https://curl.se/docs/manpage.html#--trace-ids) option is what
you need. It prepends the transfer and connection identifier to each trace
output line:
curl --trace-ascii d.txt --trace-ids http://example.com/
## See the Response
By default curl sends the response to stdout. You need to redirect it
somewhere to avoid that, most often that is done with `-o` or `-O`.
# URL
## Spec
The Uniform Resource Locator format is how you specify the address of a
particular resource on the Internet. You know these, you have seen URLs like
https://curl.se or https://example.com a million times. RFC 3986 is the
canonical spec. The formal name is not URL, it is **URI**.
## Host
The hostname is usually resolved using DNS or your /etc/hosts file to an IP
address and that is what curl communicates with. Alternatively you specify
the IP address directly in the URL instead of a name.
For development and other trying out situations, you can point to a different
IP address for a hostname than what would otherwise be used, by using curl's
[`--resolve`](https://curl.se/docs/manpage.html#--resolve) option:
curl --resolve www.example.org:80:127.0.0.1 http://www.example.org/
## Port number
Each protocol curl supports operates on a default port number, be it over TCP
or in some cases UDP. Normally you do not have to take that into
consideration, but at times you run test servers on other ports or
similar. Then you can specify the port number in the URL with a colon and a
number immediately following the hostname. Like when doing HTTP to port
1234:
curl http://www.example.org:1234/
The port number you specify in the URL is the number that the server uses to
offer its services. Sometimes you may use a proxy, and then you may
need to specify that proxy's port number separately from what curl needs to
connect to the server. Like when using an HTTP proxy on port 4321:
curl --proxy http://proxy.example.org:4321 http://remote.example.org/
## Username and password
Some services are setup to require HTTP authentication and then you need to
provide name and password which is then transferred to the remote site in
various ways depending on the exact authentication protocol used.
You can opt to either insert the user and password in the URL or you can
provide them separately:
curl http://user:password@example.org/
or
curl -u user:password http://example.org/
You need to pay attention that this kind of HTTP authentication is not what
is usually done and requested by user-oriented websites these days. They tend
to use forms and cookies instead.
## Path part
The path part is just sent off to the server to request that it sends back
the associated response. The path is what is to the right side of the slash
that follows the hostname and possibly port number.
# Fetch a page
## GET
The simplest and most common request/operation made using HTTP is to GET a
URL. The URL could itself refer to a webpage, an image or a file. The client
issues a GET request to the server and receives the document it asked for.
If you issue the command line
curl https://curl.se
you get a webpage returned in your terminal window. The entire HTML document
this URL identifies.
All HTTP replies contain a set of response headers that are normally hidden,
use curl's [`--include`](https://curl.se/docs/manpage.html#-i) (`-i`)
option to display them as well as the rest of the document.
## HEAD
You can ask the remote server for ONLY the headers by using the
[`--head`](https://curl.se/docs/manpage.html#-I) (`-I`) option which makes
curl issue a HEAD request. In some special cases servers deny the HEAD method
while others still work, which is a particular kind of annoyance.
The HEAD method is defined and made so that the server returns the headers
exactly the way it would do for a GET, but without a body. It means that you
may see a `Content-Length:` in the response headers, but there must not be an
actual body in the HEAD response.
## Multiple URLs in a single command line
A single curl command line may involve one or many URLs. The most common case
is probably to just use one, but you can specify any amount of URLs. Yes any.
No limits. You then get requests repeated over and over for all the given
URLs.
Example, send two GET requests:
curl http://url1.example.com http://url2.example.com
If you use [`--data`](https://curl.se/docs/manpage.html#-d) to POST to
the URL, using multiple URLs means that you send that same POST to all the
given URLs.
Example, send two POSTs:
curl --data name=curl http://url1.example.com http://url2.example.com
## Multiple HTTP methods in a single command line
Sometimes you need to operate on several URLs in a single command line and do
different HTTP methods on each. For this, you might enjoy the
[`--next`](https://curl.se/docs/manpage.html#-:) option. It is basically a
separator that separates a bunch of options from the next. All the URLs
before `--next` get the same method and get all the POST data merged into
one.
When curl reaches the `--next` on the command line, it resets the method and
the POST data and allow a new set.
Perhaps this is best shown with a few examples. To send first a HEAD and then
a GET:
curl -I http://example.com --next http://example.com
To first send a POST and then a GET:
curl -d score=10 http://example.com/post.cgi --next http://example.com/results.html
# HTML forms
## Forms explained
Forms are the general way a website can present an HTML page with fields for
the user to enter data in, and then press some kind of 'OK' or 'Submit'
button to get that data sent to the server. The server then typically uses
the posted data to decide how to act. Like using the entered words to search
in a database, or to add the info in a bug tracking system, display the
entered address on a map or using the info as a login-prompt verifying that
the user is allowed to see what it is about to see.
Of course there has to be some kind of program on the server end to receive
the data you send. You cannot just invent something out of the air.
## GET
A GET-form uses the method GET, as specified in HTML like:
```html
<form method="GET" action="junk.cgi">
<input type=text name="birthyear">
<input type=submit name=press value="OK">
</form>
```
In your favorite browser, this form appears with a text box to fill in and a
press-button labeled "OK". If you fill in '1905' and press the OK button,
your browser then creates a new URL to get for you. The URL gets
`junk.cgi?birthyear=1905&press=OK` appended to the path part of the previous
URL.
If the original form was seen on the page `www.example.com/when/birth.html`,
the second page you get becomes
`www.example.com/when/junk.cgi?birthyear=1905&press=OK`.
Most search engines work this way.
To make curl do the GET form post for you, just enter the expected created
URL:
curl "http://www.example.com/when/junk.cgi?birthyear=1905&press=OK"
## POST
The GET method makes all input field names get displayed in the URL field of
your browser. That is generally a good thing when you want to be able to
bookmark that page with your given data, but it is an obvious disadvantage if
you entered secret information in one of the fields or if there are a large
amount of fields creating a long and unreadable URL.
The HTTP protocol then offers the POST method. This way the client sends the
data separated from the URL and thus you do not see any of it in the URL
address field.
The form would look similar to the previous one:
```html
<form method="POST" action="junk.cgi">
<input type=text name="birthyear">
<input type=submit name=press value=" OK ">
</form>
```
And to use curl to post this form with the same data filled in as before, we
could do it like:
curl --data "birthyear=1905&press=%20OK%20" http://www.example.com/when/junk.cgi
This kind of POST uses the Content-Type `application/x-www-form-urlencoded`
and is the most widely used POST kind.
The data you send to the server MUST already be properly encoded, curl does
not do that for you. For example, if you want the data to contain a space,
you need to replace that space with `%20`, etc. Failing to comply with this
most likely causes your data to be received wrongly and messed up.
Recent curl versions can in fact url-encode POST data for you, like this:
curl --data-urlencode "name=I am Daniel" http://www.example.com
If you repeat `--data` several times on the command line, curl concatenates
all the given data pieces - and put a `&` symbol between each data segment.
## File Upload POST
Back in late 1995 they defined an additional way to post data over HTTP. It
is documented in the RFC 1867, why this method sometimes is referred to as
RFC 1867-posting.
This method is mainly designed to better support file uploads. A form that
allows a user to upload a file could be written like this in HTML:
<form method="POST" enctype='multipart/form-data' action="upload.cgi">
<input name=upload type=file>
<input type=submit name=press value="OK">
</form>
This clearly shows that the Content-Type about to be sent is
`multipart/form-data`.
To post to a form like this with curl, you enter a command line like:
curl --form upload=@localfilename --form press=OK [URL]
## Hidden Fields
A common way for HTML based applications to pass state information between
pages is to add hidden fields to the forms. Hidden fields are already filled
in, they are not displayed to the user and they get passed along just as all
the other fields.
A similar example form with one visible field, one hidden field and one
submit button could look like:
```html
<form method="POST" action="foobar.cgi">
<input type=text name="birthyear">
<input type=hidden name="person" value="daniel">
<input type=submit name="press" value="OK">
</form>
```
To POST this with curl, you do not have to think about if the fields are
hidden or not. To curl they are all the same:
curl --data "birthyear=1905&press=OK&person=daniel" [URL]
## Figure Out What A POST Looks Like
When you are about to fill in a form and send it to a server by using curl
instead of a browser, you are of course interested in sending a POST exactly
the way your browser does.
An easy way to get to see this, is to save the HTML page with the form on
your local disk, modify the 'method' to a GET, and press the submit button
(you could also change the action URL if you want to).
You then clearly see the data get appended to the URL, separated with a
`?`-letter as GET forms are supposed to.
# HTTP upload
## PUT
Perhaps the best way to upload data to an HTTP server is to use PUT. Then
again, this of course requires that someone put a program or script on the
server end that knows how to receive an HTTP PUT stream.
Put a file to an HTTP server with curl:
curl --upload-file uploadfile http://www.example.com/receive.cgi
# HTTP Authentication
## Basic Authentication
HTTP Authentication is the ability to tell the server your username and
password so that it can verify that you are allowed to do the request you are
doing. The Basic authentication used in HTTP (which is the type curl uses by
default) is **plain text** based, which means it sends username and password
only slightly obfuscated, but still fully readable by anyone that sniffs on
the network between you and the remote server.
To tell curl to use a user and password for authentication:
curl --user name:password http://www.example.com
## Other Authentication
The site might require a different authentication method (check the headers
returned by the server), and then
[`--ntlm`](https://curl.se/docs/manpage.html#--ntlm),
[`--digest`](https://curl.se/docs/manpage.html#--digest),
[`--negotiate`](https://curl.se/docs/manpage.html#--negotiate) or even
[`--anyauth`](https://curl.se/docs/manpage.html#--anyauth) might be
options that suit you.
## Proxy Authentication
Sometimes your HTTP access is only available through the use of an HTTP
proxy. This seems to be especially common at various companies. An HTTP proxy
may require its own user and password to allow the client to get through to
the Internet. To specify those with curl, run something like:
curl --proxy-user proxyuser:proxypassword curl.se
If your proxy requires the authentication to be done using the NTLM method,
use [`--proxy-ntlm`](https://curl.se/docs/manpage.html#--proxy-ntlm), if
it requires Digest use
[`--proxy-digest`](https://curl.se/docs/manpage.html#--proxy-digest).
If you use any one of these user+password options but leave out the password
part, curl prompts for the password interactively.
## Hiding credentials
Do note that when a program is run, its parameters might be possible to see
when listing the running processes of the system. Thus, other users may be
able to watch your passwords if you pass them as plain command line
options. There are ways to circumvent this.
It is worth noting that while this is how HTTP Authentication works, many
websites do not use this concept when they provide logins etc. See the Web
Login chapter further below for more details on that.
# More HTTP Headers
## Referer
An HTTP request may include a 'referer' field (yes it is misspelled), which
can be used to tell from which URL the client got to this particular
resource. Some programs/scripts check the referer field of requests to verify
that this was not arriving from an external site or an unknown page. While
this is a stupid way to check something so easily forged, many scripts still
do it. Using curl, you can put anything you want in the referer-field and
thus more easily be able to fool the server into serving your request.
Use curl to set the referer field with:
curl --referer http://www.example.come http://www.example.com
## User Agent
Similar to the referer field, all HTTP requests may set the User-Agent
field. It names what user agent (client) that is being used. Many
applications use this information to decide how to display pages. Silly web
programmers try to make different pages for users of different browsers to
make them look the best possible for their particular browsers. They usually
also do different kinds of JavaScript etc.
At times, you may learn that getting a page with curl does not return the
same page that you see when getting the page with your browser. Then you know
it is time to set the User Agent field to fool the server into thinking you
are one of those browsers.
By default, curl uses curl/VERSION, such as User-Agent: curl/8.11.0.
To make curl look like Internet Explorer 5 on a Windows 2000 box:
curl --user-agent "Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0)" [URL]
Or why not look like you are using Netscape 4.73 on an old Linux box:
curl --user-agent "Mozilla/4.73 [en] (X11; U; Linux 2.2.15 i686)" [URL]
## Redirects
## Location header
When a resource is requested from a server, the reply from the server may
include a hint about where the browser should go next to find this page, or a
new page keeping newly generated output. The header that tells the browser to
redirect is `Location:`.
curl does not follow `Location:` headers by default, but simply displays such
pages in the same manner it displays all HTTP replies. It does however
feature an option that makes it attempt to follow the `Location:` pointers.
To tell curl to follow a Location:
curl --location http://www.example.com
If you use curl to POST to a site that immediately redirects you to another
page, you can safely use [`--location`](https://curl.se/docs/manpage.html#-L)
(`-L`) and `--data`/`--form` together. curl only uses POST in the first
request, and then revert to GET in the following operations.
## Other redirects
Browsers typically support at least two other ways of redirects that curl
does not: first the html may contain a meta refresh tag that asks the browser
to load a specific URL after a set number of seconds, or it may use
JavaScript to do it.
# Cookies
## Cookie Basics
The way the web browsers do "client side state control" is by using
cookies. Cookies are just names with associated contents. The cookies are
sent to the client by the server. The server tells the client for what path
and hostname it wants the cookie sent back, and it also sends an expiration
date and a few more properties.
When a client communicates with a server with a name and path as previously
specified in a received cookie, the client sends back the cookies and their
contents to the server, unless of course they are expired.
Many applications and servers use this method to connect a series of requests
into a single logical session. To be able to use curl in such occasions, we
must be able to record and send back cookies the way the web application
expects them. The same way browsers deal with them.
## Cookie options
The simplest way to send a few cookies to the server when getting a page with
curl is to add them on the command line like:
curl --cookie "name=Daniel" http://www.example.com
Cookies are sent as common HTTP headers. This is practical as it allows curl
to record cookies simply by recording headers. Record cookies with curl by
using the [`--dump-header`](https://curl.se/docs/manpage.html#-D) (`-D`)
option like:
curl --dump-header headers_and_cookies http://www.example.com
(Take note that the
[`--cookie-jar`](https://curl.se/docs/manpage.html#-c) option described
below is a better way to store cookies.)
curl has a full blown cookie parsing engine built-in that comes in use if you
want to reconnect to a server and use cookies that were stored from a
previous connection (or hand-crafted manually to fool the server into
believing you had a previous connection). To use previously stored cookies,
you run curl like:
curl --cookie stored_cookies_in_file http://www.example.com
curl's "cookie engine" gets enabled when you use the
[`--cookie`](https://curl.se/docs/manpage.html#-b) option. If you only
want curl to understand received cookies, use `--cookie` with a file that
does not exist. Example, if you want to let curl understand cookies from a
page and follow a location (and thus possibly send back cookies it received),
you can invoke it like:
curl --cookie nada --location http://www.example.com
curl has the ability to read and write cookie files that use the same file
format that Netscape and Mozilla once used. It is a convenient way to share
cookies between scripts or invokes. The `--cookie` (`-b`) switch
automatically detects if a given file is such a cookie file and parses it,
and by using the `--cookie-jar` (`-c`) option you make curl write a new
cookie file at the end of an operation:
curl --cookie cookies.txt --cookie-jar newcookies.txt \
http://www.example.com
# HTTPS
## HTTPS is HTTP secure
There are a few ways to do secure HTTP transfers. By far the most common
protocol for doing this is what is generally known as HTTPS, HTTP over
SSL. SSL encrypts all the data that is sent and received over the network and
thus makes it harder for attackers to spy on sensitive information.
SSL (or TLS as the current version of the standard is called) offers a set of
advanced features to do secure transfers over HTTP.
curl supports encrypted fetches when built to use a TLS library and it can be
built to use one out of a fairly large set of libraries - `curl -V` shows
which one your curl was built to use (if any). To get a page from an HTTPS
server, simply run curl like:
curl https://secure.example.com
## Certificates
In the HTTPS world, you use certificates to validate that you are the one you
claim to be, as an addition to normal passwords. curl supports client- side
certificates. All certificates are locked with a passphrase, which you need
to enter before the certificate can be used by curl. The passphrase can be
specified on the command line or if not, entered interactively when curl
queries for it. Use a certificate with curl on an HTTPS server like:
curl --cert mycert.pem https://secure.example.com
curl also tries to verify that the server is who it claims to be, by
verifying the server's certificate against a locally stored CA cert bundle.
Failing the verification causes curl to deny the connection. You must then
use [`--insecure`](https://curl.se/docs/manpage.html#-k) (`-k`) in case you
want to tell curl to ignore that the server cannot be verified.
More about server certificate verification and ca cert bundles can be read in
the [`SSLCERTS` document](https://curl.se/docs/sslcerts.html).
At times you may end up with your own CA cert store and then you can tell
curl to use that to verify the server's certificate:
curl --cacert ca-bundle.pem https://example.com/
# Custom Request Elements
## Modify method and headers
Doing fancy stuff, you may need to add or change elements of a single curl
request.
For example, you can change the POST method to `PROPFIND` and send the data
as `Content-Type: text/xml` (instead of the default `Content-Type`) like
this:
curl --data "<xml>" --header "Content-Type: text/xml" \
--request PROPFIND example.com
You can delete a default header by providing one without content. Like you
can ruin the request by chopping off the `Host:` header:
curl --header "Host:" http://www.example.com
You can add headers the same way. Your server may want a `Destination:`
header, and you can add it:
curl --header "Destination: http://nowhere" http://example.com
## More on changed methods
It should be noted that curl selects which methods to use on its own
depending on what action to ask for. `-d` makes a POST, `-I` makes a HEAD and
so on. If you use the [`--request`](https://curl.se/docs/manpage.html#-X) /
`-X` option you can change the method keyword curl selects, but you do not
modify curl's behavior. This means that if you for example use -d "data" to
do a POST, you can modify the method to a `PROPFIND` with `-X` and curl still
thinks it sends a POST. You can change the normal GET to a POST method by
simply adding `-X POST` in a command line like:
curl -X POST http://example.org/
curl however still acts as if it sent a GET so it does not send any request
body etc.
# Web Login
## Some login tricks
While not strictly just HTTP related, it still causes a lot of people
problems so here's the executive run-down of how the vast majority of all
login forms work and how to login to them using curl.
It can also be noted that to do this properly in an automated fashion, you
most certainly need to script things and do multiple curl invokes etc.
First, servers mostly use cookies to track the logged-in status of the
client, so you need to capture the cookies you receive in the responses.
Then, many sites also set a special cookie on the login page (to make sure
you got there through their login page) so you should make a habit of first
getting the login-form page to capture the cookies set there.
Some web-based login systems feature various amounts of JavaScript, and
sometimes they use such code to set or modify cookie contents. Possibly they
do that to prevent programmed logins, like this manual describes how to...
Anyway, if reading the code is not enough to let you repeat the behavior
manually, capturing the HTTP requests done by your browsers and analyzing the
sent cookies is usually a working method to work out how to shortcut the
JavaScript need.
In the actual `<form>` tag for the login, lots of sites fill-in
random/session or otherwise secretly generated hidden tags and you may need
to first capture the HTML code for the login form and extract all the hidden
fields to be able to do a proper login POST. Remember that the contents need
to be URL encoded when sent in a normal POST.
# Debug
## Some debug tricks
Many times when you run curl on a site, you notice that the site does not
seem to respond the same way to your curl requests as it does to your
browser's.
Then you need to start making your curl requests more similar to your
browser's requests:
- Use the `--trace-ascii` option to store fully detailed logs of the requests
for easier analyzing and better understanding
- Make sure you check for and use cookies when needed (both reading with
`--cookie` and writing with `--cookie-jar`)
- Set user-agent (with [`-A`](https://curl.se/docs/manpage.html#-A)) to
one like a recent popular browser does
- Set referer (with [`-E`](https://curl.se/docs/manpage.html#-E)) like
it is set by the browser
- If you use POST, make sure you send all the fields and in the same order as
the browser does it.
## Check what the browsers do
A good helper to make sure you do this right, is the web browsers' developers
tools that let you view all headers you send and receive (even when using
HTTPS).
A more raw approach is to capture the HTTP traffic on the network with tools
such as Wireshark or tcpdump and check what headers that were sent and
received by the browser. (HTTPS forces you to use `SSLKEYLOGFILE` to do
that.)

# URL syntax and their use in curl
## Specifications
The official "URL syntax" is primarily defined in these two different
specifications:
- [RFC 3986](https://datatracker.ietf.org/doc/html/rfc3986) (although URL is called
"URI" in there)
- [The WHATWG URL Specification](https://url.spec.whatwg.org/)
RFC 3986 is the earlier one, and curl has always tried to adhere to that one
(since it shipped in January 2005).
The WHATWG URL spec was written later, is incompatible with the RFC 3986 and
changes over time.
## Variations
URL parsers as implemented in browsers, libraries and tools usually opt to
support one of the mentioned specifications. Bugs, differences in
interpretations and the moving nature of the WHATWG spec does however make it
unlikely that multiple parsers treat URLs the same way.
## Security
Due to the inherent differences between URL parser implementations, it is
considered a security risk to mix different implementations and assume the
same behavior.
For example, if you use one parser to check if a URL uses a good hostname or
the correct auth field, and then pass on that same URL to a *second* parser,
there is always a risk it treats the same URL differently. There is no right
and wrong in URL land, only differences of opinions.
libcurl offers a separate API to its URL parser for this reason, among others.
Applications may at times find it convenient to allow users to specify URLs
for various purposes and that string would then end up fed to curl. Getting a
URL from an external untrusted party and using it with curl brings several
security concerns:
1. If you have an application that runs as or in a server application, getting
an unfiltered URL can trick your application to access a local resource
instead of a remote resource. Protecting yourself against localhost accesses
is hard when accepting user provided URLs.
2. Such custom URLs can access other ports than you planned as port numbers
are part of the regular URL format. The combination of a local host and a
custom port number can allow external users to play tricks with your local
services.
3. Such a URL might use other schemes than you thought of or planned for.
## "RFC 3986 plus"
curl recognizes a URL syntax that we call "RFC 3986 plus". It is grounded on
the well established RFC 3986 to make sure previously written command lines
and curl using scripts remain working.
curl's URL parser allows a few deviations from the spec in order to
inter-operate better with URLs that appear in the wild.
### Spaces
A URL provided to curl cannot contain spaces. They need to be provided URL
encoded to be accepted in a URL by curl.
An exception to this rule: `Location:` response headers that indicate to a
client where a resource has been redirected to, sometimes contain spaces. This
is a violation of RFC 3986 but is fine in the WHATWG spec. curl handles these
by re-encoding them to `%20`.
### Non-ASCII
Byte values in a provided URL that are outside of the printable ASCII range
are percent-encoded by curl.
### Multiple slashes
An absolute URL always starts with a "scheme" followed by a colon. For all the
schemes curl supports, the colon must be followed by two slashes according to
RFC 3986 but not according to the WHATWG spec - which allows one to infinity
amount.
curl allows one, two or three slashes after the colon to still be considered a
valid URL.
### "scheme-less"
curl supports "URLs" that do not start with a scheme. This is not supported by
any of the specifications. This is a shortcut to entering URLs that was
supported by browsers early on and has been mimicked by curl.
Based on what the hostname starts with, curl "guesses" what protocol to use:
- `ftp.` means FTP
- `dict.` means DICT
- `ldap.` means LDAP
- `imap.` means IMAP
- `smtp.` means SMTP
- `pop3.` means POP3
- all other means HTTP
### Globbing letters
The curl command line tool supports "globbing" of URLs. It means that you can
create ranges and lists using `[N-M]` and `{one,two,three}` sequences. The
letters used for this (`[]{}`) are reserved in RFC 3986 and can therefore not
legitimately be part of such a URL.
They are however not reserved or special in the WHATWG specification, so
globbing can mess up such URLs. Globbing can be turned off for such occasions
(using `--globoff`).
# URL syntax details
A URL may consist of the following components - many of them are optional:
[scheme][divider][userinfo][hostname][port number][path][query][fragment]
Each component is separated from the following component with a divider
character or string.
For example, this could look like:
http://user:password@www.example.com:80/index.html?foo=bar#top
## Scheme
The scheme specifies the protocol to use. A curl build can support a few or
many different schemes. You can limit what schemes curl should accept.
curl supports the following schemes on URLs specified to transfer. They are
matched case insensitively:
`dict`, `file`, `ftp`, `ftps`, `gopher`, `gophers`, `http`, `https`, `imap`,
`imaps`, `ldap`, `ldaps`, `mqtt`, `pop3`, `pop3s`, `rtmp`, `rtmpe`, `rtmps`,
`rtmpt`, `rtmpte`, `rtmpts`, `rtsp`, `smb`, `smbs`, `smtp`, `smtps`, `telnet`,
`tftp`
When the URL is specified to identify a proxy, curl recognizes the following
schemes:
`http`, `https`, `socks4`, `socks4a`, `socks5`, `socks5h`, `socks`
## Userinfo
The userinfo field can be used to set username and password for
authentication purposes in this transfer. The use of this field is discouraged
since it often means passing around the password in plain text and is thus a
security risk.
URLs for IMAP, POP3 and SMTP also support *login options* as part of the
userinfo field. They are provided as a semicolon after the password and then
the options.
## Hostname
The hostname part of the URL contains the address of the server that you want
to connect to. This can be the fully qualified domain name of the server, the
local network name of the machine on your network or the IP address of the
server or machine represented by either an IPv4 or IPv6 address (within
brackets). For example:
http://www.example.com/
http://hostname/
http://192.168.0.1/
http://[2001:1890:1112:1::20]/
### "localhost"
Starting in curl 7.77.0, curl uses loopback IP addresses for the name
`localhost`: `127.0.0.1` and `::1`. It does not resolve the name using the
resolver functions.
This is done to make sure the host accessed is truly the localhost - the local
machine.
### IDNA
If curl was built with International Domain Name (IDN) support, it can also
handle hostnames using non-ASCII characters.
When built with libidn2, curl uses the IDNA 2008 standard. This is equivalent
to the WHATWG URL spec, but differs from certain browsers that use IDNA 2003
Transitional Processing. The two standards have a huge overlap but differ
slightly, perhaps most famously in how they deal with the
[German "double s"](https://en.wikipedia.org/wiki/%c3%9f)
([LATIN SMALL LETTER SHARP S](https://codepoints.net/U+00DF)).
When WinIDN is used, curl uses IDNA 2003 Transitional Processing, like the rest
of Windows.
## Port number
If there is a colon after the hostname, that should be followed by the port
number to use. 1 - 65535. curl also supports a blank port number field - but
only if the URL starts with a scheme.
If the port number is not specified in the URL, curl uses a default port
number based on the provide scheme:
DICT 2628, FTP 21, FTPS 990, GOPHER 70, GOPHERS 70, HTTP 80, HTTPS 443,
IMAP 132, IMAPS 993, LDAP 369, LDAPS 636, MQTT 1883, POP3 110, POP3S 995,
RTMP 1935, RTMPS 443, RTMPT 80, RTSP 554, SCP 22, SFTP 22, SMB 445, SMBS 445,
SMTP 25, SMTPS 465, TELNET 23, TFTP 69
# Scheme specific behaviors
## FTP
The path part of an FTP request specifies the file to retrieve and from which
directory. If the file part is omitted then libcurl downloads the directory
listing for the directory specified. If the directory is omitted then the
directory listing for the root / home directory is returned.
FTP servers typically put the user in its "home directory" after login, which
then differs between users. To explicitly specify the root directory of an FTP
server, start the path with double slash `//` or `/%2f` (2F is the hexadecimal
value of the ASCII code for the slash).
## FILE
When a `FILE://` URL is accessed on Windows systems, it can be crafted in a
way so that Windows attempts to connect to a (remote) machine when curl wants
to read or write such a path.
curl only allows the hostname part of a FILE URL to be one out of these three
alternatives: `localhost`, `127.0.0.1` or blank ("", zero characters).
Anything else makes curl fail to parse the URL.
### Windows-specific FILE details
curl accepts that the FILE URL's path starts with a "drive letter". That is a
single letter `a` to `z` followed by a colon or a pipe character (`|`).
The Windows operating system itself converts some file accesses to perform
network accesses over SMB/CIFS, through several different file path patterns.
This way, a `file://` URL passed to curl *might* be converted into a network
access inadvertently and unknowingly to curl. This is a Windows feature curl
cannot control or disable.
## IMAP
The path part of an IMAP request not only specifies the mailbox to list or
select, but can also be used to check the `UIDVALIDITY` of the mailbox, to
specify the `UID`, `SECTION` and `PARTIAL` octets of the message to fetch and
to specify what messages to search for.
A top level folder list:
imap://user:password@mail.example.com
A folder list on the user's inbox:
imap://user:password@mail.example.com/INBOX
Select the user's inbox and fetch message with `uid = 1`:
imap://user:password@mail.example.com/INBOX/;UID=1
Select the user's inbox and fetch the first message in the mail box:
imap://user:password@mail.example.com/INBOX/;MAILINDEX=1
Select the user's inbox, check the `UIDVALIDITY` of the mailbox is 50 and
fetch message 2 if it is:
imap://user:password@mail.example.com/INBOX;UIDVALIDITY=50/;UID=2
Select the user's inbox and fetch the text portion of message 3:
imap://user:password@mail.example.com/INBOX/;UID=3/;SECTION=TEXT
Select the user's inbox and fetch the first 1024 octets of message 4:
imap://user:password@mail.example.com/INBOX/;UID=4/;PARTIAL=0.1024
Select the user's inbox and check for NEW messages:
imap://user:password@mail.example.com/INBOX?NEW
Select the user's inbox and search for messages containing "shadows" in the
subject line:
imap://user:password@mail.example.com/INBOX?SUBJECT%20shadows
Searching via the query part of the URL `?` is a search request for the
results to be returned as message sequence numbers (`MAILINDEX`). It is
possible to make a search request for results to be returned as unique ID
numbers (`UID`) by using a custom curl request via `-X`. `UID` numbers are
unique per session (and multiple sessions when `UIDVALIDITY` is the same). For
example, if you are searching for `"foo bar"` in header+body (`TEXT`) and you
want the matching `MAILINDEX` numbers returned then you could search via URL:
imap://user:password@mail.example.com/INBOX?TEXT%20%22foo%20bar%22
If you want matching `UID` numbers you have to use a custom request:
imap://user:password@mail.example.com/INBOX -X "UID SEARCH TEXT \"foo bar\""
For more information about IMAP commands please see RFC 9051. For more
information about the individual components of an IMAP URL please see RFC 5092.
* Note old curl versions would `FETCH` by message sequence number when `UID`
was specified in the URL. That was a bug fixed in 7.62.0, which added
`MAILINDEX` to `FETCH` by mail sequence number.
## LDAP
The path part of an LDAP request can be used to specify the: Distinguished
Name, Attributes, Scope, Filter and Extension for an LDAP search. Each field
is separated by a question mark and when that field is not required an empty
string with the question mark separator should be included.
Search for the `DN` as `My Organization`:
ldap://ldap.example.com/o=My%20Organization
the same search but only return `postalAddress` attributes:
ldap://ldap.example.com/o=My%20Organization?postalAddress
Search for an empty `DN` and request information about the
`rootDomainNamingContext` attribute for an Active Directory server:
ldap://ldap.example.com/?rootDomainNamingContext
For more information about the individual components of an LDAP URL please see
[RFC 4516](https://datatracker.ietf.org/doc/html/rfc4516).
## POP3
The path part of a POP3 request specifies the message ID to retrieve. If the
ID is not specified then a list of waiting messages is returned instead.
## SCP
The path part of an SCP URL specifies the path and file to retrieve or
upload. The file is taken as an absolute path from the root directory on the
server.
To specify a path relative to the user's home directory on the server, prepend
`~/` to the path portion.
## SFTP
The path part of an SFTP URL specifies the file to retrieve or upload. If the
path ends with a slash (`/`) then a directory listing is returned instead of a
file. If the path is omitted entirely then the directory listing for the root
/ home directory is returned.
## SMB
The path part of an SMB request specifies the file to retrieve and from what
share and directory or the share to upload to and as such, may not be omitted.
If the username is embedded in the URL then it must contain the domain name
and as such, the backslash must be URL encoded as %2f.
When uploading to SMB, the size of the file needs to be known ahead of time,
meaning that you can upload a file passed to curl over a pipe like stdin.
curl supports SMB version 1 (only)
## SMTP
The path part of an SMTP request specifies the hostname to present during
communication with the mail server. If the path is omitted, then libcurl
attempts to resolve the local computer's hostname. However, this may not
return the fully qualified domain name that is required by some mail servers
and specifying this path allows you to set an alternative name, such as your
machine's fully qualified domain name, which you might have obtained from an
external function such as gethostname or getaddrinfo.
The default smtp port is 25. Some servers use port 587 as an alternative.
## RTMP
There is no official URL spec for RTMP so libcurl uses the URL syntax supported
by the underlying librtmp library. It has a syntax where it wants a
traditional URL, followed by a space and a series of space-separated
`name=value` pairs.
While space is not typically a "legal" letter, libcurl accepts them. When a
user wants to pass in a `#` (hash) character it is treated as a fragment and
it gets cut off by libcurl if provided literally. You have to escape it by

Version Numbers and Releases
============================
The command line tool curl and the library libcurl are individually
versioned, but they usually follow each other closely.
The version numbering is always built up using the same system:
X.Y.Z
- X is main version number
- Y is release number
- Z is patch number
## Bumping numbers
One of these numbers get bumped in each new release. The numbers to the right
of a bumped number are reset to zero.
The main version number is bumped when *really* big, world colliding changes
are made. The release number is bumped when changes are performed or
things/features are added. The patch number is bumped when the changes are
mere bugfixes.
It means that after release 1.2.3, we can release 2.0.0 if something really
big has been made, 1.3.0 if not that big changes were made or 1.2.4 if only
bugs were fixed.
Bumping, as in increasing the number with 1, is unconditionally only
affecting one of the numbers (except the ones to the right of it, that may be
set to zero). 1 becomes 2, 3 becomes 4, 9 becomes 10, 88 becomes 89 and 99
becomes 100. So, after 1.2.9 comes 1.2.10. After 3.99.3, 3.100.0 might come.
All original curl source release archives are named according to the libcurl
version (not according to the curl client version that, as said before, might
differ).
As a service to any application that might want to support new libcurl
features while still being able to build with older versions, all releases
have the libcurl version stored in the `curl/curlver.h` file using a static
numbering scheme that can be used for comparison. The version number is
defined as:
```c
#define LIBCURL_VERSION_NUM 0xXXYYZZ
```
Where `XX`, `YY` and `ZZ` are the main version, release and patch numbers in
hexadecimal. All three number fields are always represented using two digits
(eight bits each). 1.2 would appear as "0x010200" while version 9.11.7
appears as `0x090b07`.
This 6-digit hexadecimal number is always a greater number in a more recent
release. It makes comparisons with greater than and less than work.
This number is also available as three separate defines:
`LIBCURL_VERSION_MAJOR`, `LIBCURL_VERSION_MINOR` and `LIBCURL_VERSION_PATCH`.
## Past releases
This is a list of all public releases with their version numbers and release
dates. The tool was called `httpget` before 2.0, `urlget` before 4.0 then
`curl` since 4.0. `libcurl` and `curl` are always released in sync, using the
same version numbers.

# curl vulnerability disclosure policy
This document describes how security vulnerabilities are handled in the curl
project.
## Publishing Information
All known and public curl or libcurl related vulnerabilities are listed on
[the curl website security page](https://curl.se/docs/security.html).
Security vulnerabilities **should not** be entered in the project's public bug
tracker.
## Vulnerability Handling
The typical process for handling a new security vulnerability is as follows.
No information should be made public about a vulnerability until it is
formally announced at the end of this process. That means, for example, that a
bug tracker entry must NOT be created to track the issue since that makes the
issue public and it should not be discussed on any of the project's public
mailing lists. Messages associated with any commits should not make any
reference to the security nature of the commit if done prior to the public
announcement.
- The person discovering the issue, the reporter, reports the vulnerability on
[HackerOne](https://hackerone.com/curl). Issues filed there reach a handful
of selected and trusted people.
- Messages that do not relate to the reporting or managing of an undisclosed
security vulnerability in curl or libcurl are ignored and no further action
is required.
- A person in the security team responds to the original report to acknowledge
that a human has seen the report.
- The security team investigates the report and either rejects it or accepts
it. See below for examples of problems that are not considered
vulnerabilities.
- If the report is rejected, the team writes to the reporter to explain why.
- If the report is accepted, the team writes to the reporter to let them
know it is accepted and that they are working on a fix.
- The security team discusses the problem, works out a fix, considers the
impact of the problem and suggests a release schedule. This discussion
should involve the reporter as much as possible.
- The release of the information should be "as soon as possible" and is most
often synchronized with an upcoming release that contains the fix. If the
reporter, or anyone else involved, thinks the next planned release is too
far away, then a separate earlier release should be considered.
- Write a security advisory draft about the problem that explains what the
problem is, its impact, which versions it affects, solutions or workarounds,
when the release is out and make sure to credit all contributors properly.
Figure out the CWE (Common Weakness Enumeration) number for the flaw. See
[SECURITY-ADVISORY](https://curl.se/dev/advisory.html) for help on creating
the advisory.
- Request a CVE Id for the issue. curl is a CNA (CVE Numbering Authority) and
can request its own numbers.
- Update the "security advisory" with the CVE number.
- The security team commits the fix in a private branch. The commit message
should ideally contain the CVE number. If the severity level of the issue is
set to Low or Medium, the fix is allowed to get merged into the master
repository via a normal PR - but without mentioning it being a security
vulnerability.
- The monetary reward part of the bug-bounty is managed by the Internet Bug
Bounty team and the reporter is asked to request the reward from them after
the issue has been completely handled and published by curl.
- No more than seven days before release, inform
[distros@openwall](https://oss-security.openwall.org/wiki/mailing-lists/distros)
to prepare them about the upcoming public security vulnerability
announcement - attach the advisory draft for information with CVE and
current patch. 'distros' does not accept an embargo longer than 7 days and
they do not care for Windows-specific flaws.
- No more than 48 hours before the release, the private branch is merged into
the master branch and pushed. Once pushed, the information is accessible to
the public and the actual release should follow suit immediately afterwards.
The time between the push and the release is used for final tests and
reviews.
- The project team creates a release that includes the fix.
- The project team announces the release and the vulnerability to the world in
the same manner we always announce releases. It gets sent to the
curl-announce, curl-library and curl-users mailing lists.
- The security webpage on the website should get the new vulnerability
mentioned.
## security (at curl dot se)
This is a private mailing list for discussions on and about curl security
issues.
Who is on this list? There are a couple of criteria you must meet, and then we
might ask you to join the list or you can ask to join it. It really is not a
formal process. We basically only require that you have a long-term presence
in the curl project and you have shown an understanding for the project and
its way of working. You must have been around for a good while and you should
have no plans of vanishing in the near future.
We do not make the list of participants public mostly because it tends to vary
somewhat over time and a list somewhere only risks getting outdated.
## Publishing Security Advisories
1. Write up the security advisory, using markdown syntax. Use the same
subtitles as last time to maintain consistency.
2. Name the advisory file after the allocated CVE id.
3. Add a line on the top of the array in `curl-www/docs/vuln.pm`.
4. Put the new advisory markdown file in the `curl-www/docs/` directory. Add it
to the git repository.
5. Run `make` in your local web checkout and verify that things look fine.
6. On security advisory release day, push the changes on the curl-www
repository's remote master branch.
## Disclose the report
Request the issue to be disclosed. If there are sensitive details present in
the report and discussion, those should be redacted from the disclosure. The
default policy is to disclose as much as possible as soon as the vulnerability
has been published.
*All* reports submitted to the project, valid or not, should be disclosed and
made public.
## Bug Bounty
See [BUG-BOUNTY](https://curl.se/docs/bugbounty.html) for details on the
bug bounty program.
# Severity levels
The curl project's security team rates security problems using four severity
levels depending how serious we consider the problem to be. We use **Low**,
**Medium**, **High** and **Critical**. We refrain from using numerical scoring
of vulnerabilities.
We do not support CVSS as a method to grade security vulnerabilities, so we do
not set them for CVE records published by the curl project. We believe CVSS is
a broken system that often does not properly evaluate to suitable severity
levels that reflect all dimensions and factors involved. Other organizations
however set and provide CVSS scores for curl vulnerabilities. You need to
decide for yourself if you believe they know enough about the subjects
involved to make reasonable assessments. Deciding between four different
severity levels is hard enough for us.
When deciding severity level on a particular issue, we take all the factors
into account: attack vector, attack complexity, required privileges, necessary
build configuration, protocols involved, platform specifics and also what
effects a possible exploit or trigger of the issue can lead to, including
confidentiality, integrity or availability problems.
## Low
This is a security problem that is truly hard or unlikely to exploit or
trigger. Due to timing, platform requirements or the fact that options or
protocols involved are rare etc. [Past
example](https://curl.se/docs/CVE-2022-43552.html)
## Medium
This is a security problem that is less hard than **Low** to exploit or
trigger. Less strict timing, wider platform availability or involving more
widely used options or protocols. A problem that usually needs something else
to also happen to become serious. [Past
example](https://curl.se/docs/CVE-2022-32206.html)
## High
This issue is in itself a serious problem with real world impact. Flaws that
can easily compromise the confidentiality, integrity or availability of
resources. Exploiting or triggering this problem is not hard. [Past
example](https://curl.se/docs/CVE-2019-3822.html)
## Critical
Easily exploitable by a remote unauthenticated attacker and lead to system
compromise (arbitrary code execution) without requiring user interaction, with
a common configuration on a popular platform. This issue has few restrictions
and requirements and can be exploited easily using most curl configurations.
[Past example](https://curl.se/docs/CVE-2000-0973.html)
# Not security issues
This is an incomplete list of issues that are not considered vulnerabilities.
## Small memory leaks
We do not consider a small memory leak a security problem; even if the amount
of allocated memory grows by a small amount every now and then. Long-living
applications and services already need to have countermeasures and deal with
growing memory usage, be it leaks or just increased use. A small memory or
resource leak is then expected to *not* cause a security problem.
Of course there can be a discussion if a leak is small or not. A large leak
can be considered a security problem due to the DOS risk. If leaked memory
contains sensitive data it might also qualify as a security problem.
## Never-ending transfers
We do not consider flaws that cause a transfer to never end to be a security
problem. There are already several benign and likely reasons for transfers to
stall and never end, so applications that cannot deal with never-ending
transfers already need to have counter-measures established.
If the problem avoids the regular counter-measures when it causes a never-
ending transfer, it might be a security problem.
## Not practically possible
If the flaw or vulnerability cannot practically get executed on existing
hardware it is not a security problem.
## API misuse
If a reported issue only triggers by an application using the API in a way
that is not documented to work or even documented to not work, it is probably
not going to be considered a security problem. We only guarantee secure and
proper functionality when the APIs are used as expected and documented.
There can be a discussion about what the documentation actually means and how
to interpret the text, which might end up with us still agreeing that it is a
security problem.
## Local attackers already present
When an issue can only be attacked or misused by an attacker present on the
local system or network, the bar is raised. If a local user wrongfully has
elevated rights on your system enough to attack curl, they can probably
already do much worse harm and the problem is not really in curl.
## Debug & Experiments
Vulnerabilities in features which are off by default (in the build) and
documented as experimental, or exist only in debug mode, are not eligible for a
reward and we do not consider them security problems.
The same applies to scripts and software which are not installed by default
through the make install rule.
## URL inconsistencies
URL parser inconsistencies between browsers and curl are expected and are not
considered security vulnerabilities. The WHATWG URL Specification and RFC
3986+ (the plus meaning that it is an extended version) [are not completely
interoperable](https://github.com/bagder/docs/blob/master/URL-interop.md).
Obvious parser bugs can still be vulnerabilities of course.
## Visible command line arguments
The curl command blanks the contents of a number of command line arguments to
prevent them from appearing in process listings. It does not blank all
arguments, even though some that are not blanked might contain sensitive
data. We consider this functionality a best-effort and omissions are not
security vulnerabilities.
- not all systems allow the arguments to be blanked in the first place
- since curl blanks the argument itself they are readable for a short moment
no matter what
- virtually every argument can contain sensitive data, depending on use
- blanking all arguments would make it impractical for users to differentiate
curl command lines in process listings
## Busy-loops
Busy-loops that consume 100% CPU time but eventually end (perhaps due to a set
timeout value or otherwise) are not considered security problems. Applications
are supposed to already handle situations when the transfer loop legitimately
consumes 100% CPU time, so while a prolonged such busy-loop is a nasty bug, we
do not consider it a security problem.
## Saving files
curl cannot protect against attacks where an attacker has write access to the
same directory where curl is directed to save files.
## Tricking a user to run a command line
A creative, misleading or funny looking command line is not a security
problem. The curl command line tool takes options and URLs on the command line
and if an attacker can trick the user to run a specifically crafted curl
command line, all bets are off. Such an attacker can just as well have the
user run a much worse command that can do something fatal (like
`sudo rm -rf /`).
## Terminal output and escape sequences
Content that is transferred from a server and gets displayed in a terminal by
curl may contain escape sequences or use other tricks to fool the user. This
is curl working as designed and is not a curl security problem. Escape
sequences, moving cursor, changing color etc, is also frequently used for
good. To reduce the risk of getting fooled, save files and browse them after
download using a display method that minimizes risks.
## NULL dereferences and crashes
If a malicious server can trigger a NULL dereference in curl or otherwise
cause curl to crash (and nothing worse), chances are big that we do not
consider that a security problem.
Malicious servers can already cause considerable harm and denial of service
like scenarios without having to trigger such code paths. For example by
stalling, being terribly slow or by delivering enormous amounts of data.
Additionally, applications are expected to handle "normal" crashes without
that being the end of the world.
There need to be more and special circumstances to treat such problems as
security issues.
## Legacy dependencies
Problems that can be triggered only by the use of a *legacy dependency* are
not considered security problems.
A *legacy dependency* is here defined as:
- the legacy version was released over ten years ago AND
- the legacy version is no longer in use by any existing still supported
operating system or distribution AND
- there are modern versions of equivalent or better functionality offered and
in common use
## weak algorithms required for functionality
curl supports several algorithms that are considered weak, like DES and MD5.
These algorithms are still not curl security vulnerabilities or security
problems as they are only used when the users explicitly ask for their use by
using the protocols or options that require the use of those algorithms.
When servers upgrade to use secure alternatives, curl users should use those
options/protocols.

# curl man page generator
`managen` is the curl man page generator. It generates a single nroff man page
output from the set of sources files in this directory.
The `mainpage.idx` file lists all files that are rendered in that order to
produce the output. The magic `%options` keyword inserts all command line
options documented.
The `%options` documentation is created with one source file for each
supported command line option.
The documentation file format is described below. It is meant to look similar
to markdown which is why it uses `.md` file extensions.
## Option files
Each command line option is described in a file named `<long name>.d`, where
option name is written without any prefixing dashes. Like the filename for the
`-v, --verbose` option is named `verbose.d`.
Each file has a set of meta-data in the top of the file, followed by a body of
text.
The documentation files that do not document options have no meta-data part.
A line that starts with `<!--` is a comment. It should also end with `-->`.
### Meta-data
--- (start of meta-data)
Added: (version number in which this was added)
Arg: (the argument the option takes)
c: (copyright line)
Example:
- (an example command line, without "curl" and can use `$URL`)
- (another example)
Experimental: yes (if so)
Help: (short text for the --help output for this option)
Long: (long form name, without dashes)
Magic: (description of "magic" options)
Multi: single/append/boolean/mutex/custom/per-URL (if used more than once)
Mutexed: (space separated list of options this overrides, no dashes)
Protocols: (space separated list for which protocols this option works)
Requires: (space separated list of features this requires, no dashes)
Scope: global (if the option is global)
See-also:
- (a related option, no dashes)
- (another related option, no dashes)
Short: (single letter, without dash)
SPDX-License-Identifier: curl
Tags: (space separated list)
--- (end of meta-data)
### Body
The body of the description. Only refer to options with their long form option
version, like `--verbose`. The output generator replaces such option with the
correct markup that shows both short and long version.
Text written within `*asterisks*` is shown using italics. Text within two
`**asterisks**` is shown using bold.
Text that is prefixed with a space is treated like an "example" and gets
output in monospace.
Within the body, describe a list of items like this:
## item 1
description
## item 2
second description
The list is automatically terminated at end of file, or you can do it
explicitly with an empty "header":
##
Angle brackets (`<>`) need to be escaped when used in text like `\<` and
`\>`. This, to ensure that the text renders nicely as markdown.
### Headers
The `#` header can be used by non-option files and it produces a
`.SH` output.
If the `#` header is used for a command line option file, that header is
simply ignored in the generated output. It can still serve a purpose in the
source file as it helps the user identify what option the file is for.
### Variables
There are three different "variables" that can be used when creating the
output. They need to be written within backticks in the source file (to escape
getting spellchecked by CI jobs): `%DATE`, `%VERSION` and `%GLOBALS`.
## Generate
`managen mainpage [list of markdown option file names]`
This command outputs a single huge nroff file, meant to become `curl.1`. The
full curl man page.
`managen ascii [list of markdown option file names]`
This command outputs a single text file, meant to become `curl.txt`. The full
curl man page in text format, used to build `tool_hugehelp.c`.
`managen listhelp`
Generates a full `curl --help` output for all known command line options.

# DESCRIPTION
**curl** is a tool for transferring data from or to a server using URLs. It
supports these protocols: DICT, FILE, FTP, FTPS, GOPHER, GOPHERS, HTTP, HTTPS,
IMAP, IMAPS, LDAP, LDAPS, MQTT, POP3, POP3S, RTMP, RTMPS, RTSP, SCP, SFTP,
SMB, SMBS, SMTP, SMTPS, TELNET, TFTP, WS and WSS.
curl is powered by libcurl for all transfer-related features. See
*libcurl(3)* for details.

# ENVIRONMENT
The environment variables can be specified in lower case or upper case. The
lower case version has precedence. `http_proxy` is an exception as it is only
available in lower case.
Using an environment variable to set the proxy has the same effect as using
the --proxy option.
## `http_proxy` [protocol://]<host>[:port]
Sets the proxy server to use for HTTP.
## `HTTPS_PROXY` [protocol://]<host>[:port]
Sets the proxy server to use for HTTPS.
## `[url-protocol]_PROXY` [protocol://]<host>[:port]
Sets the proxy server to use for [url-protocol], where the protocol is a
protocol that curl supports and as specified in a URL. FTP, FTPS, POP3, IMAP,
SMTP, LDAP, etc.
## `ALL_PROXY` [protocol://]<host>[:port]
Sets the proxy server to use if no protocol-specific proxy is set.
## `NO_PROXY` <comma-separated list of hosts/domains>
list of hostnames that should not go through any proxy. If set to an asterisk
'*' only, it matches all hosts. Each name in this list is matched as either a
domain name which contains the hostname, or the hostname itself.
This environment variable disables use of the proxy even when specified with
the --proxy option. That is
NO_PROXY=direct.example.com curl -x http://proxy.example.com
http://direct.example.com
accesses the target URL directly, and
NO_PROXY=direct.example.com curl -x http://proxy.example.com
http://somewhere.example.com
accesses the target URL through the proxy.
The list of hostnames can also include numerical IP addresses, and IPv6
versions should then be given without enclosing brackets.
IP addresses can be specified using CIDR notation: an appended slash and
number specifies the number of "network bits" out of the address to use in the
comparison (added in 7.86.0). For example "192.168.0.0/16" would match all
addresses starting with "192.168".
## `APPDATA` <dir>
On Windows, this variable is used when trying to find the home directory. If
the primary home variables are all unset.
## `COLUMNS` <terminal width>
If set, the specified number of characters is used as the terminal width when
the alternative progress-bar is shown. If not set, curl tries to figure it out
using other ways.
## `CURL_CA_BUNDLE` <file>
If set, it is used as the --cacert value. This environment variable is ignored
if Schannel is used as the TLS backend.
## `CURL_HOME` <dir>
If set, is the first variable curl checks when trying to find its home
directory. If not set, it continues to check *XDG_CONFIG_HOME*
## `CURL_SSL_BACKEND` <TLS backend>
If curl was built with support for "MultiSSL", meaning that it has built-in
support for more than one TLS backend, this environment variable can be set to
the case insensitive name of the particular backend to use when curl is
invoked. Setting a name that is not a built-in alternative makes curl stay
with the default.
SSL backend names (case-insensitive): **gnutls**, **mbedtls**, **openssl**,
**rustls**, **schannel**, **wolfssl**
## `HOME` <dir>
If set, this is used to find the home directory when that is needed. Like when
looking for the default .curlrc. *CURL_HOME* and *XDG_CONFIG_HOME*
have preference.
## `QLOGDIR` <directory name>
If curl was built with HTTP/3 support, setting this environment variable to a
local directory makes curl produce **qlogs** in that directory, using file
names named after the destination connection id (in hex). Do note that these
files can become rather large. Works with the ngtcp2 and quiche QUIC backends.
## `SHELL`
Used on VMS when trying to detect if using a **DCL** or a **Unix** shell.
## `SSL_CERT_DIR` <dir>
If set, it is used as the --capath value. This environment variable is ignored
if Schannel is used as the TLS backend.
## `SSL_CERT_FILE` <path>
If set, it is used as the --cacert value. This environment variable is ignored
if Schannel is used as the TLS backend.
## `SSLKEYLOGFILE` <filename>
If you set this environment variable to a filename, curl stores TLS secrets
from its connections in that file when invoked to enable you to analyze the
TLS traffic in real time using network analyzing tools such as Wireshark. This
works with the following TLS backends: OpenSSL, LibreSSL (TLS 1.2 max),
BoringSSL, GnuTLS, wolfSSL and Rustls.
## `USERPROFILE` <dir>
On Windows, this variable is used when trying to find the home directory. If
the other, primary, variables are all unset. If set, curl uses the path
**"$USERPROFILE\Application Data"**.
## `XDG_CONFIG_HOME` <dir>
If *CURL_HOME* is not set, this variable is checked when looking for a
default .curlrc file.

# EXIT CODES
There are a bunch of different error codes and their corresponding error
messages that may appear under error conditions. At the time of this writing,
the exit codes are:
## 0
Success. The operation completed successfully according to the instructions.
## 1
Unsupported protocol. This build of curl has no support for this protocol.
## 2
Failed to initialize.
## 3
URL malformed. The syntax was not correct.
## 4
A feature or option that was needed to perform the desired request was not
enabled or was explicitly disabled at build-time. To make curl able to do
this, you probably need another build of libcurl.
## 5
Could not resolve proxy. The given proxy host could not be resolved.
## 6
Could not resolve host. The given remote host could not be resolved.
## 7
Failed to connect to host.
## 8
Weird server reply. The server sent data curl could not parse.
## 9
FTP access denied. The server denied login or denied access to the particular
resource or directory you wanted to reach. Most often you tried to change to a
directory that does not exist on the server.
## 10
FTP accept failed. While waiting for the server to connect back when an active
FTP session is used, an error code was sent over the control connection or
similar.
## 11
FTP weird PASS reply. curl could not parse the reply sent to the PASS request.
## 12
During an active FTP session while waiting for the server to connect back to
curl, the timeout expired.
## 13
FTP weird PASV reply, curl could not parse the reply sent to the PASV request.
## 14
FTP weird 227 format. curl could not parse the 227-line the server sent.
## 15
FTP cannot use host. Could not resolve the host IP we got in the 227-line.
## 16
HTTP/2 error. A problem was detected in the HTTP2 framing layer. This is
somewhat generic and can be one out of several problems, see the error message
for details.
## 17
FTP could not set binary. Could not change transfer method to binary.
## 18
Partial file. Only a part of the file was transferred.
## 19
FTP could not download/access the given file, the RETR (or similar) command
failed.
## 21
FTP quote error. A quote command returned error from the server.
## 22
HTTP page not retrieved. The requested URL was not found or returned another
error with the HTTP error code being 400 or above. This return code only
appears if --fail is used.
## 23
Write error. curl could not write data to a local filesystem or similar.
## 25
Failed starting the upload. For FTP, the server typically denied the STOR
command.
## 26
Read error. Various reading problems.
## 27
Out of memory. A memory allocation request failed.
## 28
Operation timeout. The specified time-out period was reached according to the
conditions.
## 30
FTP PORT failed. The PORT command failed. Not all FTP servers support the PORT
command, try doing a transfer using PASV instead.
## 31
FTP could not use REST. The REST command failed. This command is used for
resumed FTP transfers.
## 33
HTTP range error. The range "command" did not work.
## 34
HTTP post error. Internal post-request generation error.
## 35
SSL connect error. The SSL handshaking failed.

## 45
Interface error. A specified outgoing interface could not be used.
## 47
Too many redirects. When following redirects, curl hit the maximum amount.
## 48

option to curl that was passed on to libcurl and rejected. Read up in the
manual.
## 49
Malformed telnet option.
## 52
The server did not reply anything, which here is considered an error.

# GLOBBING
You can specify multiple URLs or parts of URLs by writing lists within braces
or ranges within brackets. We call this "globbing".
Provide a list with three different names like this:
"http://site.{one,two,three}.com"
Do sequences of alphanumeric series by using [] as in:
"ftp://ftp.example.com/file[1-100].txt"
With leading zeroes:
"ftp://ftp.example.com/file[001-100].txt"
With letters through the alphabet:
"ftp://ftp.example.com/file[a-z].txt"
Nested sequences are not supported, but you can use several ones next to each
other:
"http://example.com/archive[1996-1999]/vol[1-4]/part{a,b,c}.html"
You can specify a step counter for the ranges to get every Nth number or
letter:
"http://example.com/file[1-100:10].txt"
"http://example.com/file[a-z:2].txt"
When using [] or {} sequences when invoked from a command line prompt, you
probably have to put the full URL within double quotes to avoid the shell from
interfering with it. This also goes for other characters treated special, like
for example '&', '?' and '*'.
Switch off globbing with --globoff.

# OPTIONS
Options start with one or two dashes. Many of the options require an
additional value next to them. If provided text does not start with a dash, it
is presumed to be and treated as a URL.
The short "single-dash" form of the options, -d for example, may be used with
or without a space between it and its value, although a space is a recommended
separator. The long double-dash form, --data for example, requires a space
between it and its value.
Short version options that do not need any additional values can be used
immediately next to each other, like for example you can specify all the
options *-O*, *-L* and *-v* at once as *-OLv*.
In general, all boolean options are enabled with --**option** and yet again
disabled with --**no-**option. That is, you use the same option name but
prefix it with `no-`. However, in this list we mostly only list and show the
--**option** version of them.
When --next is used, it resets the parser state and you start again with a
clean option state, except for the options that are global. Global options
retain their values and meaning even after --next.
The first argument that is exactly two dashes (`--`), marks the end of
options; any argument after the end of options is interpreted as a URL
argument even if it starts with a dash.
curl does little to no verification of the contents of command line arguments.
Passing in "creative octets" like newlines might trigger unexpected results.
The following options are global: `%GLOBALS`.

# OUTPUT
If not told otherwise, curl writes the received data to stdout. It can be
instructed to instead save that data into a local file, using the --output or
--remote-name options. If curl is given multiple URLs to transfer on the
command line, it similarly needs multiple options for where to save them.
curl does not parse or otherwise "understand" the content it gets or writes as
output. It does no encoding or decoding, unless explicitly asked to with

# PROGRESS METER
curl normally displays a progress meter during operations, indicating the
amount of transferred data, transfer speeds and estimated time left, etc. The
progress meter displays the transfer rate in bytes per second. The suffixes
(k, M, G, T, P) are 1024 based. For example 1k is 1024 bytes. 1M is 1048576
bytes.
curl displays this data to the terminal by default, so if you invoke curl to
do an operation and it is about to write data to the terminal, it *disables*
the progress meter as otherwise it would mess up the output mixing progress
meter and response data.
If you want a progress meter for HTTP POST or PUT requests, you need to
redirect the response output to a file, using shell redirect (\>), --output
or similar.
This does not apply to FTP upload as that operation does not spit out any
response data to the terminal.
If you prefer a progress bar instead of the regular meter, --progress-bar is
your friend. You can also disable the progress meter completely with the
--silent option.

# PROTOCOLS
curl supports numerous protocols, or put in URL terms: schemes. Your
particular build may not support them all.
## DICT
Lets you lookup words using online dictionaries.
## FILE
Read or write local files. curl does not support accessing file:// URL
remotely, but when running on Microsoft Windows using the native UNC approach
works.
## FTP(S)
curl supports the File Transfer Protocol with a lot of tweaks and levers. With
or without using TLS.
## GOPHER(S)
Retrieve files.
## HTTP(S)
curl supports HTTP with numerous options and variations. It can speak HTTP
version 0.9, 1.0, 1.1, 2 and 3 depending on build options and the correct
command line options.
## IMAP(S)
Using the mail reading protocol, curl can download emails for you. With or
without using TLS.
## LDAP(S)
curl can do directory lookups for you, with or without TLS.
## MQTT
curl supports MQTT version 3. Downloading over MQTT equals subscribing to a
topic while uploading/posting equals publishing on a topic. MQTT over TLS is not
supported (yet).
## POP3(S)
Downloading from a pop3 server means getting an email. With or without using
TLS.
## RTMP(S)
The **Realtime Messaging Protocol** is primarily used to serve streaming media
and curl can download it.
## RTSP
curl supports RTSP 1.0 downloads.
## SCP
curl supports SSH version 2 scp transfers.
## SFTP
curl supports SFTP (draft 5) done over SSH version 2.
## SMB(S)
curl supports SMB version 1 for upload and download.
## SMTP(S)
Uploading contents to an SMTP server means sending an email. With or without
TLS.
## TELNET
Fetching a telnet URL starts an interactive session where it sends what it
reads on stdin and outputs what the server sends it.
## TFTP
curl can do TFTP downloads and uploads.
## WS(S)
WebSocket done over HTTP/1. WSS implies that it works over HTTPS.

# PROXY PROTOCOL PREFIXES
The proxy string may be specified with a protocol:// prefix to specify
alternative proxy protocols. (Added in 7.21.7)
If no protocol is specified in the proxy string or if the string does not
match a supported one, the proxy is treated as an HTTP proxy.
The supported proxy protocol prefixes are as follows:
## http://
Makes it use it as an HTTP proxy. The default if no scheme prefix is used.
## https://
Makes it treated as an **HTTPS** proxy.
## socks4://
Makes it the equivalent of --socks4
## socks4a://
Makes it the equivalent of --socks4a
## socks5://
Makes it the equivalent of --socks5
## socks5h://
Makes it the equivalent of --socks5-hostname

# URL
The URL syntax is protocol-dependent. You find a detailed description in
RFC 3986.
If you provide a URL without a leading **protocol://** scheme, curl guesses
what protocol you want. It then defaults to HTTP but assumes others based on
often-used hostname prefixes. For example, for hostnames starting with `ftp.`
curl assumes you want FTP.
You can specify any amount of URLs on the command line. They are fetched in a
sequential manner in the specified order unless you use --parallel. You can
specify command line options and URLs mixed and in any order on the command
line.
curl attempts to reuse connections when doing multiple transfers, so that
getting many files from the same server do not use multiple connects and setup
handshakes. This improves speed. Connection reuse can only be done for URLs
specified for a single command line invocation and cannot be performed between
separate curl runs.
Provide an IPv6 zone id in the URL with an escaped percentage sign. Like in
"http://[fe80::3%25eth0]/"
Everything provided on the command line that is not a command line option or
its argument, curl assumes is a URL and treats it as such.

# VARIABLES
curl supports command line variables (added in 8.3.0). Set variables with
--variable name=content or --variable name@file (where `file` can be stdin if
set to a single dash (-)).
Variable contents can be expanded in option parameters using `{{name}}` if the
option name is prefixed with `--expand-`. This gets the contents of the
variable `name` inserted, or a blank if the name does not exist as a
variable. Insert `{{` verbatim in the string by prefixing it with a backslash,
like `\{{`.
You access and expand environment variables by first importing them. You
select to either require the environment variable to be set or you can provide
a default value in case it is not already set. Plain `--variable %name`
imports the variable called `name` but exits with an error if that environment
variable is not already set. To provide a default value if it is not set, use
`--variable %name=content` or `--variable %name@content`.
Example. Get the USER environment variable into the URL, fail if USER is not
set:
--variable '%USER'
--expand-url = "https://example.com/api/{{USER}}/method"
When expanding variables, curl supports a set of functions that can make the
variable contents more convenient to use. It can trim leading and trailing
white space with `trim`, it can output the contents as a JSON quoted string
with `json`, URL encode the string with `url`, base64 encode it with `b64` and
base64 decode it with `64dec`. To apply functions to a variable expansion, add
them colon separated to the right side of the variable. Variable content
holding null bytes that are not encoded when expanded causes an error.
Example: get the contents of a file called $HOME/.secret into a variable
called "fix". Make sure that the content is trimmed and percent-encoded when
sent as POST data:
--variable %HOME
--expand-variable fix@{{HOME}}/.secret
--expand-data "{{fix:trim:url}}"
https://example.com/
Command line variables and expansions were added in 8.3.0.

method, which you can do with --basic, --digest, --ntlm, and --negotiate.
Using --anyauth is not recommended if you do uploads from stdin, since it may
require data to be sent twice and then the client must be able to rewind. If
the need should arise when uploading from stdin, the upload operation fails.

Example:

# `--cacert`
Use the specified certificate file to verify the peer. The file may contain
multiple CA certificates. The certificate(s) must be in PEM format. Normally
curl is built to use a default file for this, so this option is typically used
to alter that default file.
curl recognizes the environment variable named 'CURL_CA_BUNDLE' if it is set
and the TLS backend is not Schannel, and uses the given path as a path to a CA
cert bundle. This option overrides that variable.
(Windows) curl automatically looks for a CA certs file named
'curl-ca-bundle.crt', either in the same directory as curl.exe, or in the
Current Working Directory, or in any folder along your PATH.
curl 8.11.0 added a build-time option to disable this search behavior, and
another option to restrict search to the application's directory.
(Schannel) This option is supported for Schannel in Windows 7 or later (added
in 7.60.0). This option is supported for backward compatibility with other SSL
engines; instead it is recommended to use Windows' store of root certificates
(the default for Schannel).

separator (e.g. `path1:path2:path3` on Unix-style platforms for `path1;path2;path3` on Windows).
The certificates must be in PEM format, and if curl is built against OpenSSL, the
directory must have been processed using the c_rehash utility supplied with
OpenSSL. Using --capath can allow OpenSSL-powered curl to make SSL-connections
much more efficiently than using --cacert if the --cacert file contains many
CA certificates.

Use the specified client certificate file when getting a file with HTTPS, FTPS

that this option assumes a certificate file that is the private key and the
client certificate concatenated. See --cert and --key to specify them
independently.
In the \<certificate\> portion of the argument, you must escape the character
`:` as `\:` so that it is not recognized as the password delimiter. Similarly,
you must escape the double quote character as \" so that it is not recognized
as an escape character.
If curl is built against OpenSSL, and the engine pkcs11 or pkcs11
provider is available, then a PKCS#11 URI (RFC 7512) can be used to specify a
certificate located in a PKCS#11 device. A string beginning with `pkcs11:` is
interpreted as a PKCS#11 URI. If a PKCS#11 URI is provided, then the --engine
option is set as `pkcs11` if none was provided and the --cert-type option is
set as `ENG` or `PROV` if none was provided (depending on OpenSSL version).
If curl is built against GnuTLS, a PKCS#11 URI can be used to specify
a certificate located in a PKCS#11 device. A string beginning with `pkcs11:`
is interpreted as a PKCS#11 URI.
(Schannel) Client certificates must be specified by a path expression to a
certificate store. (Loading *PFX* is not supported; you can import it to a
store first). You can use "\<store location\>\\<store name\>\\<thumbprint\>"
to refer to a certificate in the system certificates store, for example,
*"CurrentUser\MY\934a7ac6f8a5d579285a74fa61e19f23ddfe8d7a"*. Thumbprint is
usually a SHA-1 hex string which you can see in certificate details. Following
store locations are supported: *CurrentUser*, *LocalMachine*,
*CurrentService*, *Services*, *CurrentUserGroupPolicy*,
*LocalMachineGroupPolicy* and *LocalMachineEnterprise*.

# `--config`
Specify a text file to read curl arguments from. The command line arguments
found in the text file are used as if they were provided on the command
line.
Options and their parameters must be specified on the same line in the file,
separated by whitespace, colon, or the equals sign. Long option names can
optionally be given in the config file without the initial double dashes and
if so, the colon or equals characters can be used as separators. If the option
is specified with one or two dashes, there can be no colon or equals character
between the option and its parameter.
If the parameter contains whitespace or starts with a colon (:) or equals sign
(=), it must be specified enclosed within double quotes ("like this"). Within
double quotes the following escape sequences are available: \\, \", \t, \n, \r
and \v. A backslash preceding any other letter is ignored.
If the first non-blank column of a config line is a '#' character, that line
is treated as a comment.
Only write one option per physical line in the config file. A single line is
required to be no more than 10 megabytes (since 8.2.0).
Specify the filename to --config as minus "-" to make curl read the file from
stdin.
Note that to be able to specify a URL in the config file, you need to specify
it using the --url option, and not by simply writing the URL on its own
line. So, it could look similar to this:
url = "https://curl.se/docs/"
# --- Example file ---
# this is a comment
url = "example.com"
output = "curlhere.html"
user-agent = "superagent/1.0"
# and fetch another URL too
url = "example.com/docs/manpage.html"
-O
referer = "http://nowhereatall.example.com/"
# --- End of example file ---
When curl is invoked, it (unless --disable is used) checks for a default
config file and uses it if found, even when --config is used. The default
config file is checked for in the following places in this order:
1) **"$CURL_HOME/.curlrc"**
2) **"$XDG_CONFIG_HOME/curlrc"** (Added in 7.73.0)
3) **"$HOME/.curlrc"**
4) Windows: **"%USERPROFILE%\.curlrc"**
5) Windows: **"%APPDATA%\.curlrc"**
6) Windows: **"%USERPROFILE%\Application Data\.curlrc"**
7) Non-Windows: use getpwuid to find the home directory
8) On Windows, if it finds no *.curlrc* file in the sequence described above, it
checks for one in the same directory the curl executable is placed.
On Windows two filenames are checked per location: *.curlrc* and *_curlrc*,
preferring the former. Older versions on Windows checked for *_curlrc* only.

# `--connect-timeout`
Maximum time in seconds that you allow curl's connection to take. This only
limits the connection phase, so if curl connects within the given period it
continues - if not it exits.
This option accepts decimal values (added in 7.32.0). The decimal value needs
to be provided using a dot (.) as decimal separator - not the local version
even if it might be using another separator.
The connection phase is considered complete when the DNS lookup and requested
TCP, TLS or QUIC handshakes are done.

# `--connect-to`
For a request intended for the `HOST1:PORT1` pair, connect to `HOST2:PORT2`
instead. This option is only used to establish the network connection. It does
NOT affect the hostname/port number that is used for TLS/SSL (e.g. SNI,
certificate verification) or for the application protocols.
`HOST1` and `PORT1` may be empty strings, meaning any host or any port number.
`HOST2` and `PORT2` may also be empty strings, meaning use the request's
original hostname and port number.
A hostname specified to this option is compared as a string, so it needs to
match the name used in the request URL. It can be either numerical such as
`127.0.0.1` or the full host name such as `example.org`.
Example: redirect connects from the example.com hostname to 127.0.0.1
independently of port number:
curl --connect-to example.com::127.0.0.1: https://example.com/
Example: redirect connects from all hostnames to 127.0.0.1 independently of
port number:
curl --connect-to ::127.0.0.1: http://example.com/

# `--continue-at`
Resume a previous transfer from the given byte offset. The given offset is the
exact number of bytes that are skipped, counting from the beginning of the
source file before it is transferred to the destination. If used with uploads,
the FTP server command SIZE is not used by curl.
Use "-C -" to instruct curl to automatically find out where/how to resume the
transfer. It then uses the given output/input files to figure that out.
When using this option for HTTP uploads using POST or PUT, functionality is
not guaranteed. The HTTP protocol has no standard interoperable resume upload
and curl uses a set of headers for this purpose that once proved working for
some servers and have been left for those who find that useful.
This command line option is mutually exclusive with --range: you can only use
one of them for a single transfer.
The --no-clobber and --remove-on-error options cannot be used together with
--continue-at.

# `--cookie-jar`
Specify to which file you want curl to write all cookies after a completed
operation. curl writes all cookies from its in-memory cookie storage to the
given file at the end of operations. Even if no cookies are known, a file is
created so that it removes any formerly existing cookies from the file. The
file uses the Netscape cookie file format. If you set the filename to a single
minus, "-", the cookies are written to stdout.
The file specified with --cookie-jar is only used for output. No cookies are
read from the file. To read cookies, use the --cookie option. Both options
can specify the same file.
This command line option activates the cookie engine that makes curl record
and use cookies. The --cookie option also activates it.
If the cookie jar cannot be created or written to, the whole curl operation
does not fail or even report an error clearly. Using --verbose gets a warning
displayed, but that is the only visible feedback you get about this possibly
lethal situation.

# `--cookie`
This option has two slightly separate cookie sending functions.
Either: pass the exact data to send to the HTTP server in the Cookie header.
It is supposedly data previously received from the server in a `Set-Cookie:`
line. The data should be in the format `NAME1=VALUE1; NAME2=VALUE2`. When
given a set of specific cookies, curl populates its cookie header with this
content explicitly in all outgoing request(s). If multiple requests are done
due to authentication, followed redirects or similar, they all get this cookie
header passed on.
Or: If no `=` symbol is used in the argument, it is instead treated as a
filename to read previously stored cookie from. This option also activates the
cookie engine which makes curl record incoming cookies, which may be handy if
you are using this in combination with the --location option or do multiple
URL transfers on the same invoke.
If the filename is a single minus ("-"), curl reads the contents from stdin.
If the filename is an empty string ("") and is the only cookie input, curl
activates the cookie engine without any cookies.
The file format of the file to read cookies from should be plain HTTP headers
(Set-Cookie style) or the Netscape/Mozilla cookie file format.
The file specified with --cookie is only used as input. No cookies are written
to that file. To store cookies, use the --cookie-jar option.
If you use the Set-Cookie file format and do not specify a domain then the
cookie is not sent since the domain never matches. To address this, set a
domain in Set-Cookie line (doing that includes subdomains) or preferably: use
the Netscape format.
Users often want to both read cookies from a file and write updated cookies
back to a file, so using both --cookie and --cookie-jar in the same command
line is common.
If curl is built with PSL (**Public Suffix List**) support, it detects and
discards cookies that are specified for such suffix domains that should not be
allowed to have cookies. If curl is *not* built with PSL support, it has no
ability to stop super cookies.

# `--create-dirs`
When used in conjunction with the --output option, curl creates the necessary
local directory hierarchy as needed. This option creates the directories
mentioned with the --output option combined with the path possibly set with
--output-dir. If the combined output filename uses no directory, or if the
directories it mentions already exist, no directories are created.
Created directories are made with mode 0750 on Unix-style file systems.
To create remote directories when using FTP or SFTP, try --ftp-create-dirs.
