fips-203

A hybrid cryptography engine unifying classical and post-quantum algorithms — RSA, ECDSA, AES-GCM, ML-KEM (FIPS 203), ML-DSA (FIPS 204).

Post-quantum polyfill for the Web Cryptography API: ML-KEM (FIPS 203) and ML-DSA (FIPS 204) per the WICG Modern Algorithms draft — native-first with a wasm engine, plus a DHKEM-over-ECDH (RFC 9180) migration extension.

Browser PQ encryption/decryption tool

Production-tested post-quantum cryptography patterns. ML-DSA-65 + ML-KEM-768. Used in production at KXCO.

Shared post-quantum cryptographic and encoding utilities designed for relevant frameworks and modern usage.
