### Prerequisites

|
||||
- GCC compiler
|
||||
- OpenSSL development libraries (`libssl-dev` on Ubuntu/Debian)
|

- Git (for version tracking)
|

- Make

**Note: OpenSSL is no longer required! This implementation is now completely self-contained.**

## Security Features
|
||||
|
||||
- Uses `/dev/urandom` for cryptographically secure random number generation
|
||||
- Optional keyboard entropy mixing using HKDF (Hash-based Key Derivation Function)
|
||||
- SHA-256 pad integrity verification
|
||||
- Optional keyboard entropy mixing using simple XOR operations
|
||||
- Custom 256-bit XOR checksum for pad identification (encrypted with pad data)
|
||||
- Read-only pad files to prevent accidental modification
|
||||
- State tracking to prevent pad reuse
|
||||
- **Zero external crypto dependencies** - completely self-contained implementation
