  • v0.2.0

    96bea996 · fix cryptohandler not being in the jlizard namespace · 
    - Added CryptoHandler class to jlizard namespace

- moved overview before the TOC in the README.md
- fixed the markdown code display for the gmac example

- Removed redundant main.cpp
- Removed some redundant comments

  • v0.1.0-alpha.2

    4d28dca8 · update changelog.md · 
    - Removed redundant calculate_digest signature. Kept only signature in active use, old function was not used
  and doesn't adhere to error propagation methodology applied for other functions
- Updated Readme.md with reference to ByteArray library
- Reorganize the structure of readme and improve examples

- Fixed some bugs in the provided examples

  • v0.1.0-alpha.1

    69bb3540 · add utility overloads for gcm and improve testing and docs · 
    - Initial implementation of CryptoHandler class with support for:
    - AES encryption in CBC and GCM modes
    - SHA-256 message digest functionality
    - HMAC generation with SHA-256
    - CBC-MAC authentication
    - GMAC authentication for GCM mode
- Comprehensive set of unit tests:
    - AES-CBC encryption/decryption with and without padding
    - AES-GCM authenticated encryption
    - SHA-256 digest calculation and truncation
    - HMAC-SHA256 verification against RFC 4231 test vectors
    - CBC-MAC and GMAC authentication
    - Error handling for mismatched modes and wrong keys
- New edge case tests for AES-GCM:
    - Behavior when tag is missing during decryption
    - Handling of tags smaller than required 16 bytes
    - Validation of empty tag buffers
    - Support for oversized tag buffers
- Proper error handling and reporting through std::expected
- Comprehensive validation of cryptographic parameters
- Support for legacy crypto algorithms through providers

- Secure memory handling with ByteArray class that wipes sensitive data
- Proper IV handling for CBC and GCM modes
- Complete tag validation for authenticated encryption
- Implementation follows cryptographic best practices
- OpenSSL-based cryptographic operations
