I Maintain cryptopp-modern (a modernised Crypto++ fork)

2026.3.0 adds NIST PQC algorithms: - ML-KEM (FIPS 203) - ML-DSA (FIPS 204) - SLH-DSA (FIPS 205) - X-Wing Hybrid KEM (X25519 - ML-KEM-768)

Docs + API links are in the announcement

Feedback welcome, especially: - Packaging priority (vcpkg vs Conan) - CI/build friction (MSVC/Linux/macOS) - missing examples you'd want for real world adoption
