[0.1.8] - 2025-12-26

Added

Python 3 Implementation (clients/python3/)

  • Full protocol implementation: Complete Dice52-PQ protocol in Python 3
  • Post-quantum cryptography: Uses kyber-py and dilithium-py (pure Python implementations)
  • Symmetric cryptography: Uses pycryptodome for ChaCha20-Poly1305 and HKDF-SHA-256
  • Package structure: Proper Python package with pyproject.toml for pip installation
  • Module files:
    • dice52/__init__.py - Package exports
    • dice52/types.py - Protocol constants and data types
    • dice52/error.py - Exception classes
    • dice52/crypto.py - ChaCha20-Poly1305 encryption/decryption
    • dice52/kdf.py - HKDF-SHA256 key derivation functions
    • dice52/handshake.py - Kyber768/Dilithium3 handshake
    • dice52/session.py - Session management with ratcheting and Ko enhancement
    • dice52/demo.py - Demo application
  • Testing: Unit tests in tests/test_session.py
  • Build targets: Local Makefile with install, test, demo, clean targets

Java Implementation (clients/java/)

  • Full protocol implementation: Complete Dice52-PQ protocol in Java 17
  • Post-quantum cryptography: Uses Bouncy Castle 1.78 for ML-KEM-768 (Kyber) and ML-DSA-65 (Dilithium)
  • Symmetric cryptography: Bouncy Castle for ChaCha20-Poly1305 and HKDF-SHA-256
  • Maven project: Standard Maven structure with pom.xml
  • Source files:
    • io.dice52.Constants - Protocol constants
    • io.dice52.Types - Data types and message structures
    • io.dice52.Dice52Exception - Exception hierarchy
    • io.dice52.Crypto - ChaCha20-Poly1305 encryption/decryption
    • io.dice52.Kdf - HKDF-SHA256 key derivation functions
    • io.dice52.Handshake - Kyber768/Dilithium3 handshake
    • io.dice52.Session - Session management with ratcheting and Ko enhancement
    • io.dice52.Demo - Demo application
  • Testing: JUnit 5 tests in SessionTest.java
  • Build targets: Local Makefile with build, test, demo, clean targets

Features (Both Implementations)

  • Authenticated handshake with ML-KEM-768 and ML-DSA-65 signatures
  • Ko enhancement protocol (commit-reveal) for defense-in-depth
  • PQ ratcheting with signature verification
  • Paranoid mode support with configurable parameters
  • Message encryption/decryption with ChaCha20-Poly1305
  • HKDF key derivation per RFC specification
  • Thread-safe session management
