Modern, fast cryptographic hash function\n- ✨ **Argon2** - RFC 9106 password hashing (Argon2d, Argon2i, Argon2id)\n- 🔒 **Security Patches** - Marvin attack fix (CVE-2023-50979), fault injection fix (CVE-2024-28285), ESIGN improvements\n- 📅 **Calendar Versioning** - Clear release dates (YEAR.MONTH.INCREMENT format)\n- 🔄 **Active Maintenance** - Regular updates and improvements\n- ✅ **Drop-in Compatible** - Uses same `CryptoPP` namespace\n\n---\n\n\n## What's New in 2026.2.1\n\n- 🔧 **DSA/ECDSA Fix** - Fixed invalid signature (r=0 or s=0) handling per FIPS 186-4\n- 🔄 **Probabilistic Signatures** - Retry with fresh random k until valid (64-attempt cap)\n- ⚠️ **Deterministic Signatures** - Abort with exception (API limitation)\n\nSee [RELEASE-2026.2.1.md](RELEASE-2026.2.1.md) for details and [Security.md](Security.md) for the full advisory.\n\n---\n\n## Quick Build\n\n### CMake (Recommended)\n\n```bash\ncmake --preset=default\ncmake --build build/default\n./build/default/cryptest.exe v\n```\n\n### GNUmakefile\n\n```bash\nmake -j$(nproc)\n./cryptest.exe v\n```\n\nSee [CMAKE.md](CMAKE.md) or [GNUMAKEFILE.md](GNUMAKEFILE.md) for detailed build instructions.\n\n---\n\n## Documentation\n\n- **[cryptopp-modern.com](https://cryptopp-modern.com)** - Full API and algorithm documentation\n- **[GETTING_STARTED.md](GETTING_STARTED.md)** - Quick start guide with code examples\n- **[CMAKE.md](CMAKE.md)** - CMake build system documentation\n- **[GNUMAKEFILE.md](GNUMAKEFILE.md)** - GNUmakefile build system documentation\n- **[ROADMAP.md](ROADMAP.md)** - Development roadmap and future plans\n- **[FORK.md](FORK.md)** - Relationship to upstream Crypto++\n- **[Readme.txt](Readme.txt)** - Complete algorithm list and instructions\n- **[Install.txt](Install.txt)** - Detailed installation guide\n- **[LICENSE](LICENSE)** - Boost Software License 1.0\n\n---\n\n## Why Fork?\n\n**Upstream Crypto++ Status:**\n- Last release: 8.9.0 (October 1, 2023)\n- Version encoding limitation (cannot represent 8.10.0)\n- Slower development pace\n\n**cryptopp-modern Goals:**\n- Active maintenance and regular releases\n- Modern algorithm support (BLAKE3, Argon2, future: post-quantum)\n- Better code organization\n- Modern CMake build system\n- Calendar versioning\n- Community-driven development\n\nSee [FORK.md](FORK.md) for detailed explanation.\n\n---\n\n## Features\n\n### Cryptographic Algorithms\n\n**Hash Functions:**\n- SHA-2, SHA-3, BLAKE2b/s, **BLAKE3** ⭐\n- MD5, RIPEMD, Tiger, Whirlpool, SipHash\n\n**Password Hashing / KDF:**\n- **Argon2 (d/i/id)** ⭐ RFC 9106\n- PBKDF2, Scrypt, HKDF\n\n**Symmetric Encryption:**\n- AES, ChaCha20, Serpent, Twofish, Camellia, ARIA\n- Modes: GCM, CCM, EAX, CBC, CTR, and more\n\n**Public Key Cryptography:**\n- RSA, DSA, ECDSA, Ed25519\n- Diffie-Hellman, ECIES, ElGamal\n\n**Message Authentication:**\n- HMAC, CMAC, GMAC, Poly1305\n\nSee [Readme.txt](Readme.txt) for complete algorithm list.\n\n---\n\n## Migration from Crypto++ 8.9.0\n\n**Good news:** Most code works unchanged!\n\n### Compatible ✓\n- All existing algorithms and APIs\n- Same `CryptoPP` namespace\n- Version checks: `#if CRYPTOPP_VERSION \u003e= N`\n\n### Changed ⚠️\n- Version encoding: Now `YEAR*10000 + MONTH*100 + INCREMENT`\n- Version parsing: Use `/10000` for year, `(n/100)%100` for month\n\n**Example:**\n```cpp\n// Old (8.9.0)\nconst int major = CRYPTOPP_VERSION / 100;  // Gets 8\n\n// New (2025.11.0)\nconst int year = CRYPTOPP_VERSION / 10000;  // Gets 2025\nconst int month = (CRYPTOPP_VERSION / 100) % 100;  // Gets 11\n```\n\n---\n\n## Contributing\n\nContributions are welcome! Areas where you can help:\n\n- 🐛 Bug reports and fixes\n- ✨ New algorithm implementations\n- 📚 Documentation improvements\n- 🧪 Tests and test vectors\n- 🔧 Build system enhancements\n\nIf you're migrating from Crypto++ 8.9.0 and encounter any issues, please open an issue – migration feedback is especially valuable.\n\nPlease:\n1.
