# Generic Automatic Version Increment System for Any Repository
|
||||
|
||||
Here's a generalized implementation guide for adding automatic versioning to any project:
|
||||
|
||||
## Core Concept
|
||||
**Automatic patch version increment with each build** - Every build automatically increments the patch version: v0.1.0 → v0.1.1 → v0.1.2, etc.
|
||||
|
||||
## Implementation Steps
|
||||
|
||||
### 1. Add Version Increment Function to Build Script
|
||||
Add this function to your build script (bash example):
|
||||
|
||||
```bash
|
||||
# Function to automatically increment version
|
||||
increment_version() {
|
||||
echo "[INFO] Incrementing version..."
|
||||
|
||||
# Check if we're in a git repository
|
||||
if ! git rev-parse --git-dir > /dev/null 2>&1; then
|
||||
echo "[WARNING] Not in a git repository - skipping version increment"
|
||||
return 0
|
||||
fi
|
||||
|
||||
# Get the highest version tag (not chronologically latest)
|
||||
LATEST_TAG=$(git tag -l 'v*.*.*' | sort -V | tail -n 1 || echo "v0.1.0")
|
||||
if [[ -z "$LATEST_TAG" ]]; then
|
||||
LATEST_TAG="v0.1.0"
|
||||
fi
|
||||
|
||||
# Extract version components (remove 'v' prefix)
|
||||
VERSION=${LATEST_TAG#v}
|
||||
|
||||
# Parse major.minor.patch using regex
|
||||
if [[ $VERSION =~ ^([0-9]+)\.([0-9]+)\.([0-9]+)$ ]]; then
|
||||
MAJOR=${BASH_REMATCH[1]}
|
||||
MINOR=${BASH_REMATCH[2]}
|
||||
PATCH=${BASH_REMATCH[3]}
|
||||
else
|
||||
echo "[ERROR] Invalid version format in tag: $LATEST_TAG"
|
||||
echo "[ERROR] Expected format: v0.1.0"
|
||||
return 1
|
||||
fi
|
||||
|
||||
# Increment patch version
|
||||
NEW_PATCH=$((PATCH + 1))
|
||||
NEW_VERSION="v${MAJOR}.${MINOR}.${NEW_PATCH}"
|
||||
|
||||
echo "[INFO] Current version: $LATEST_TAG"
|
||||
echo "[INFO] New version: $NEW_VERSION"
|
||||
|
||||
# Create new git tag
|
||||
if git tag "$NEW_VERSION" 2>/dev/null; then
|
||||
echo "[SUCCESS] Created new version tag: $NEW_VERSION"
|
||||
else
|
||||
echo "[WARNING] Tag $NEW_VERSION already exists - using existing version"
|
||||
NEW_VERSION=$LATEST_TAG
|
||||
fi
|
||||
|
||||
# Update VERSION file for compatibility
|
||||
echo "${NEW_VERSION#v}" > VERSION
|
||||
echo "[SUCCESS] Updated VERSION file to ${NEW_VERSION#v}"
|
||||
}
|
||||
```
|
||||
|
||||
### 2. Generate Version Header Files (For C/C++ Projects)
|
||||
Add this to the increment_version function:
|
||||
|
||||
```bash
|
||||
# Generate version.h header file (adjust path as needed)
|
||||
cat > src/version.h << EOF
|
||||
/*
|
||||
* Auto-Generated Version Header
|
||||
* DO NOT EDIT THIS FILE MANUALLY - Generated by build script
|
||||
*/
|
||||
|
||||
#ifndef VERSION_H
|
||||
#define VERSION_H
|
||||
|
||||
#define VERSION_MAJOR ${MAJOR}
|
||||
#define VERSION_MINOR ${MINOR}
|
||||
#define VERSION_PATCH ${NEW_PATCH}
|
||||
#define VERSION_STRING "${MAJOR}.${MINOR}.${NEW_PATCH}"
|
||||
#define VERSION_TAG "${NEW_VERSION}"
|
||||
|
||||
/* Build information */
|
||||
#define BUILD_DATE "$(date +%Y-%m-%d)"
|
||||
#define BUILD_TIME "$(date +%H:%M:%S)"
|
||||
#define BUILD_TIMESTAMP "$(date '+%Y-%m-%d %H:%M:%S')"
|
||||
|
||||
/* Git information */
|
||||
#define GIT_HASH "$(git rev-parse --short HEAD 2>/dev/null || echo 'unknown')"
|
||||
#define GIT_BRANCH "$(git rev-parse --abbrev-ref HEAD 2>/dev/null || echo 'unknown')"
|
||||
|
||||
/* Display versions */
|
||||
#define VERSION_DISPLAY "${NEW_VERSION}"
|
||||
#define VERSION_FULL_DISPLAY "${NEW_VERSION} ($(date '+%Y-%m-%d %H:%M:%S'), $(git rev-parse --short HEAD 2>/dev/null || echo 'unknown'))"
|
||||
|
||||
/* Version API functions */
|
||||
const char* get_version(void);
|
||||
const char* get_version_full(void);
|
||||
const char* get_build_info(void);
|
||||
|
||||
#endif /* VERSION_H */
|
||||
EOF
|
||||
|
||||
# Generate version.c implementation file
|
||||
cat > src/version.c << EOF
|
||||
/*
|
||||
* Auto-Generated Version Implementation
|
||||
* DO NOT EDIT THIS FILE MANUALLY - Generated by build script
|
||||
*/
|
||||
|
||||
#include "version.h"
|
||||
|
||||
const char* get_version(void) {
|
||||
return VERSION_TAG;
|
||||
}
|
||||
|
||||
const char* get_version_full(void) {
|
||||
return VERSION_FULL_DISPLAY;
|
||||
}
|
||||
|
||||
const char* get_build_info(void) {
|
||||
return "Built on " BUILD_DATE " at " BUILD_TIME " from commit " GIT_HASH " on branch " GIT_BRANCH;
|
||||
}
|
||||
EOF
|
||||
```
|
||||
|
||||
### 3. Generate Version File for Other Languages
|
||||
|
||||
**Python (`src/__version__.py`):**
|
||||
```bash
|
||||
cat > src/__version__.py << EOF
|
||||
"""Auto-generated version file"""
|
||||
__version__ = "${MAJOR}.${MINOR}.${NEW_PATCH}"
|
||||
__version_tag__ = "${NEW_VERSION}"
|
||||
__build_date__ = "$(date +%Y-%m-%d)"
|
||||
__build_time__ = "$(date +%H:%M:%S)"
|
||||
__git_hash__ = "$(git rev-parse --short HEAD 2>/dev/null || echo 'unknown')"
|
||||
__git_branch__ = "$(git rev-parse --abbrev-ref HEAD 2>/dev/null || echo 'unknown')"
|
||||
EOF
|
||||
```
|
||||
|
||||
**JavaScript/Node.js (update `package.json`):**
|
||||
```bash
|
||||
# Update package.json version field
|
||||
if [ -f package.json ]; then
|
||||
sed -i "s/\"version\": \".*\"/\"version\": \"${MAJOR}.${MINOR}.${NEW_PATCH}\"/" package.json
|
||||
fi
|
||||
```
|
||||
|
||||
**Rust (update `Cargo.toml`):**
|
||||
```bash
|
||||
if [ -f Cargo.toml ]; then
|
||||
sed -i "s/^version = \".*\"/version = \"${MAJOR}.${MINOR}.${NEW_PATCH}\"/" Cargo.toml
|
||||
fi
|
||||
```
|
||||
|
||||
**Go (generate `version.go`):**
|
||||
```bash
|
||||
cat > version.go << EOF
|
||||
// Auto-generated version file
|
||||
package main
|
||||
|
||||
const (
|
||||
VersionMajor = ${MAJOR}
|
||||
VersionMinor = ${MINOR}
|
||||
VersionPatch = ${NEW_PATCH}
|
||||
VersionString = "${MAJOR}.${MINOR}.${NEW_PATCH}"
|
||||
VersionTag = "${NEW_VERSION}"
|
||||
BuildDate = "$(date +%Y-%m-%d)"
|
||||
BuildTime = "$(date +%H:%M:%S)"
|
||||
GitHash = "$(git rev-parse --short HEAD 2>/dev/null || echo 'unknown')"
|
||||
GitBranch = "$(git rev-parse --abbrev-ref HEAD 2>/dev/null || echo 'unknown')"
|
||||
)
|
||||
EOF
|
||||
```
|
||||
|
||||
**Java (generate `Version.java`):**
|
||||
```bash
|
||||
cat > src/main/java/Version.java << EOF
|
||||
// Auto-generated version class
|
||||
public class Version {
|
||||
public static final int VERSION_MAJOR = ${MAJOR};
|
||||
public static final int VERSION_MINOR = ${MINOR};
|
||||
public static final int VERSION_PATCH = ${NEW_PATCH};
|
||||
public static final String VERSION_STRING = "${MAJOR}.${MINOR}.${NEW_PATCH}";
|
||||
public static final String VERSION_TAG = "${NEW_VERSION}";
|
||||
public static final String BUILD_DATE = "$(date +%Y-%m-%d)";
|
||||
public static final String BUILD_TIME = "$(date +%H:%M:%S)";
|
||||
public static final String GIT_HASH = "$(git rev-parse --short HEAD 2>/dev/null || echo 'unknown')";
|
||||
public static final String GIT_BRANCH = "$(git rev-parse --abbrev-ref HEAD 2>/dev/null || echo 'unknown')";
|
||||
}
|
||||
EOF
|
||||
```
|
||||
|
||||
### 4. Integrate into Build Targets
|
||||
Call `increment_version` before your main build commands:
|
||||
|
||||
```bash
|
||||
build_library() {
|
||||
increment_version
|
||||
echo "[INFO] Building library..."
|
||||
# Your actual build commands here
|
||||
make clean && make
|
||||
}
|
||||
|
||||
build_release() {
|
||||
increment_version
|
||||
echo "[INFO] Building release..."
|
||||
# Your release build commands
|
||||
}
|
||||
|
||||
build_package() {
|
||||
increment_version
|
||||
echo "[INFO] Building package..."
|
||||
# Your packaging commands
|
||||
}
|
||||
```
|
||||
|
||||
### 5. Update .gitignore
|
||||
Add generated version files to `.gitignore`:
|
||||
|
||||
```gitignore
|
||||
# Auto-generated version files
|
||||
src/version.h
|
||||
src/version.c
|
||||
src/__version__.py
|
||||
version.go
|
||||
src/main/java/Version.java
|
||||
VERSION
|
||||
```
|
||||
|
||||
### 6. Update Build System Files
|
||||
|
||||
**For Makefile projects:**
|
||||
```makefile
|
||||
# Add version.c to your source files
|
||||
SOURCES = main.c utils.c version.c
|
||||
```
|
||||
|
||||
**For CMake projects:**
|
||||
```cmake
|
||||
# Add version files to your target
|
||||
target_sources(your_target PRIVATE src/version.c)
|
||||
```
|
||||
|
||||
**For Node.js projects:**
|
||||
```json
|
||||
{
|
||||
"scripts": {
|
||||
"build": "node build.js && increment_version",
|
||||
"version": "node -e \"console.log(require('./package.json').version)\""
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 7. Create Initial Version Tag
|
||||
```bash
|
||||
# Start with initial version
|
||||
git tag v0.1.0
|
||||
```
|
||||
|
||||
## Usage Pattern
|
||||
```bash
|
||||
./build.sh # v0.1.0 → v0.1.1
|
||||
./build.sh release # v0.1.1 → v0.1.2
|
||||
./build.sh package # v0.1.2 → v0.1.3
|
||||
```
|
||||
|
||||
## Manual Version Control
|
||||
|
||||
### Major/Minor Version Bumps
|
||||
```bash
|
||||
# For feature releases (minor bump)
|
||||
git tag v0.2.0 # Next build: v0.2.1
|
||||
|
||||
# For breaking changes (major bump)
|
||||
git tag v1.0.0 # Next build: v1.0.1
|
||||
```
|
||||
|
||||
### Version Reset
|
||||
```bash
|
||||
# Delete incorrect tags (if needed)
|
||||
git tag -d v0.2.1
|
||||
git push origin --delete v0.2.1 # If pushed to remote
|
||||
|
||||
# Create correct base version
|
||||
git tag v0.2.0
|
||||
|
||||
# Next build will create v0.2.1
|
||||
```
|
||||
|
||||
## Example Build Script Template
|
||||
```bash
|
||||
#!/bin/bash
|
||||
set -e
|
||||
|
||||
# Colors for output
|
||||
RED='\033[0;31m'
|
||||
GREEN='\033[0;32m'
|
||||
YELLOW='\033[1;33m'
|
||||
BLUE='\033[0;34m'
|
||||
NC='\033[0m'
|
||||
|
||||
print_status() { echo -e "${BLUE}[INFO]${NC} $1"; }
|
||||
print_success() { echo -e "${GREEN}[SUCCESS]${NC} $1"; }
|
||||
print_warning() { echo -e "${YELLOW}[WARNING]${NC} $1"; }
|
||||
print_error() { echo -e "${RED}[ERROR]${NC} $1"; }
|
||||
|
||||
# Insert increment_version function here
|
||||
|
||||
case "${1:-build}" in
|
||||
build)
|
||||
increment_version
|
||||
print_status "Building project..."
|
||||
# Your build commands
|
||||
;;
|
||||
clean)
|
||||
print_status "Cleaning build artifacts..."
|
||||
# Your clean commands
|
||||
;;
|
||||
test)
|
||||
print_status "Running tests..."
|
||||
# Your test commands (no version increment)
|
||||
;;
|
||||
release)
|
||||
increment_version
|
||||
print_status "Building release..."
|
||||
# Your release commands
|
||||
;;
|
||||
*)
|
||||
echo "Usage: $0 {build|clean|test|release}"
|
||||
exit 1
|
||||
;;
|
||||
esac
|
||||
```
|
||||
|
||||
## Benefits
|
||||
1. **Zero maintenance** - No manual version editing
|
||||
2. **Build traceability** - Every build has unique version + metadata
|
||||
3. **Git integration** - Automatic version tags
|
||||
4. **Language agnostic** - Adapt generation for any language
|
||||
5. **CI/CD friendly** - Works in automated environments
|
||||
6. **Rollback friendly** - Easy to revert to previous versions
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Version Not Incrementing
|
||||
- Ensure you're in a git repository
|
||||
- Check that git tags exist: `git tag --list`
|
||||
- Verify tag format matches `v*.*.*` pattern
|
||||
|
||||
### Tag Already Exists
|
||||
If a tag already exists, the build continues with existing version:
|
||||
```
|
||||
[WARNING] Tag v0.2.1 already exists - using existing version
|
||||
```
|
||||
|
||||
### Missing Git Information
|
||||
If git is unavailable, version files show "unknown" for git hash and branch.

|
||||
- **Interactive text encryption/decryption**
|
||||
- **Hash-based file naming** for content verification
|
||||
- **Read-only pad protection** prevents accidental corruption
|
||||
|
||||
## Dependencies
|
||||
|
||||
- OpenSSL development libraries (`libssl-dev` on Ubuntu/Debian)
|
||||
- GCC compiler
|
||||
|
||||
### Install dependencies on Ubuntu/Debian:
|
||||
```bash
|
||||
sudo apt update
|
||||
sudo apt install libssl-dev build-essential
|
||||
```
|
||||
|
||||
## Building
|
||||
|
||||
```bash
|
||||
make
|
||||
```
|
||||
|
||||
This will create the `otp` executable.
|
||||
|
||||
## Usage Modes
|
||||
|
||||
### Interactive Mode (Recommended)
|
||||
|
||||
Simply run the program without arguments:
|
||||
|
||||
```bash
|
||||
./otp
|
||||
```
|
||||
|
||||
This launches a menu-driven interface:
|
||||
```
|
||||
=== OTP Cipher Interactive Mode ===
|
||||
Version: OTP-CIPHER 2.0
|
||||
|
||||
=== Main Menu ===
|
||||
1. Generate new pad
|
||||
2. Encrypt message
|
||||
3. Decrypt message
|
||||
4. List available pads
|
||||
5. Show pad information
|
||||
6. Exit
|
||||
```
|
||||
|
||||
### Command Line Mode
|
||||
|
||||
For automation and scripting:
|
||||
|
||||
```bash
|
||||
./otp generate <size> # Generate new pad
|
||||
./otp encrypt <pad_hash_prefix> # Encrypt text
|
||||
./otp decrypt <pad_hash_prefix> # Decrypt message
|
||||
./otp list # List available pads
|
||||
```
|
||||
|
||||
## Smart Size Parsing
|
||||
|
||||
The system intelligently parses size specifications:
|
||||
|
||||
```bash
|
||||
./otp generate 1024 # 1024 bytes
|
||||
./otp generate 5MB # 5 megabytes
|
||||
./otp generate 2GB # 2 gigabytes
|
||||
./otp generate 10TB # 10 terabytes
|
||||
./otp generate 1.5GB # 1.5 gigabytes (decimal supported)
|
||||
```
|
||||
|
||||
**Supported units:** K, KB, M, MB, G, GB, T, TB (case insensitive)
|
||||
|
||||
## Pad Selection
|
||||
|
||||
Multiple convenient ways to select pads:
|
||||
|
||||
1. **Full hash**: `./otp encrypt a1b2c3d4e5f6789012345678901234567890abcdef...`
|
||||
2. **Hash prefix**: `./otp encrypt a1b2c3d4`
|
||||
3. **Pad number**: `./otp encrypt 1` (from list output)
|
||||
|
||||
## Example Workflows
|
||||
|
||||
### Basic Usage
|
||||
```bash
|
||||
# Generate a 1GB pad
|
||||
./otp generate 1GB

|
||||
Pad hash: a1b2c3d4e5f6789012345678901234567890abcdef1234567890abcdef123456
|
||||
|
||||

|
||||
|
||||
## Security Features
|
||||
|
||||
### Perfect Forward Secrecy
|
||||
Each message uses a unique portion of the pad that is never reused, ensuring perfect forward secrecy.
|
||||
|
||||
### Content-Based Integrity
|
||||
- **SHA-256 file naming**: Pad files named by their hash ensure content verification
|
||||
- **Integrity checking**: Embedded hashes detect pad corruption/tampering
|
||||
- **Read-only protection**: Pad files automatically set to read-only after creation
|
||||
|
||||
### ASCII Armor Format
|
||||
Messages use a PGP-like ASCII armor format:
|
||||
```
|
||||
-----BEGIN OTP MESSAGE-----
|
||||
Version: OTP-CIPHER 2.0
|
||||
Pad-Hash: a1b2c3d4e5f6789012345678901234567890abcdef1234567890abcdef123456
|
||||
Pad-Offset: 0
|
||||
|
||||
U2VjcmV0IG1lc3NhZ2U=
|
||||
-----END OTP MESSAGE-----
|
||||
```
|
||||
|
||||
### State Management
|
||||
- **Automatic tracking**: Prevents pad reuse through state files
|
||||
- **Portable state**: State stored separately from immutable pad data
|
||||
- **Usage statistics**: Track pad consumption and remaining capacity
|
||||
|
||||
## File Structure
|
||||
|
||||
**Source Files:**
|
||||
- `otp.c` - Complete implementation (850+ lines)

|
||||
|
||||
**Generated Files:**
|
||||
- `otp` - Compiled executable
|
||||
- `<hash>.pad` - Pad files (read-only, hash-named)
|
||||
- `<hash>.state` - State files (writable, tracks usage)
|
||||
|

|
||||
```bash
|
||||
./otp list
|
||||
No. Hash (first 16 chars) Size Used
|
||||
--- ------------------- ---------- ----------
|
||||
1 a1b2c3d4e5f67890 5.00TB 2.1GB
|
||||
2 f9e8d7c6b5a49321 1.00GB 0.5GB
|
||||
```
|
||||
|
||||
### Multiple Pad Management
|
||||
- List all available pads
|
||||
- Show detailed information per pad
|
||||
- Track usage across multiple pads
|
||||
- Quick selection by number or prefix
|
||||
|
||||
## Performance
|
||||
|
||||
### Size Limits
|
||||
- **Theoretical maximum**: 18 exabytes (uint64_t limit)
|
||||
- **Practical maximum**: Limited by available disk space
|
||||
- **Tested up to**: 10TB+ on modern systems
|
||||
- **Generation speed**: ~80-120 MB/s (system dependent)
|
||||
|
||||
### Memory Efficiency
|
||||
- **Streaming operation**: Constant memory usage regardless of pad size
|
||||
- **64KB buffers**: Efficient I/O without excessive memory consumption
|
||||
- **Large file support**: Handles multi-terabyte pads efficiently
|
||||
|
||||
## Security Notes
|
||||
|
||||
⚠️ **Critical Security Requirements:**
|
||||
|
||||
1. **Never reuse pad data** - Automatic prevention through state tracking
|
||||
2. **Secure pad distribution** - Use secure channels for pad sharing
|
||||
3. **Physical security** - Protect pad files like encryption keys
|
||||
4. **Verify integrity** - Always check pad hash verification during decryption
|
||||
5. **Secure systems** - Generate pads on trusted systems with good entropy
|
||||
|
||||
## Installation
|
||||
|
||||
### Local Installation

|
||||
- **Perfect randomness**: Cryptographically secure entropy
|
||||
- **Key length**: Equal to or greater than message length
|
||||
- **Single use**: Each pad portion used exactly once
|
||||
- **Secure distribution**: Pads shared through secure channels
|
||||
|
||||
This implementation satisfies all requirements for perfect cryptographic security while providing modern usability features for practical deployment.
