NoisePQC++: A C++23 Implementation of the Noise Protocol Framework with Post-Quantum Cryptography

NoisePQC++ is a modern, type-safe implementation of the Noise Protocol Framework using C++23 modules with support for post-quantum cryptography and hybrid forward secrecy. The library provides cryptographic protocol building blocks including AEAD ciphers, hash functions, Diffie-Hellman key exchange, and NIST-standardized ML-KEM for quantum-resistant key encapsulation.
