# ============================================================================
# Cryptography Algorithm Toolkit - Requirements
# Python Version: 3.10+ (Recommended: 3.11+)
# ============================================================================

# Core Cryptographic Libraries (REQUIRED)
cryptography>=42.0.0           # Modern cryptographic primitives
pycryptodome>=3.20.0           # Legacy algorithm implementations (AES, DES, RSA, etc.)
blake3>=1.0.0                  # BLAKE3 hash algorithm

# Dependencies (REQUIRED - automatically installed with above)
cffi>=2.0.0                    # C Foreign Function Interface (for cryptography)
pycparser>=3.0                 # C parser (for cffi)

# Optional Cryptographic Libraries (RECOMMENDED but not blocking)
# These have graceful fallbacks if not installed
# Uncomment to install:
# twofish>=0.3.0              # Twofish block cipher (optional)
# tiger>=0.3                  # Tiger hash algorithm (requires C++ build tools on Windows)
# whirlpool>=1.0.0            # Whirlpool hash algorithm (requires C++ build tools on Windows)

# Note: pygost (Russian GOST algorithms) is not available on PyPI
# GOST modules (Magma, Kuznyechik) use Python implementations instead

# 2. Activate virtual environment:
#    Windows:  .\.venv\Scripts\activate
#    Linux:    source .venv/bin/activate
#
# 3. Install dependencies:
#    pip install -r requirements.txt
#
# 4. Run the toolkit:
#    python main.py
