s2n is a C-based security library and TLS protocol implementation that serves as a secure network transport layer. It provides a modular cryptographic backend interface to encrypt data streams, manage handshakes, and handle mutual authentication between peers. The project focuses on post-quantum cryptography, integrating quantum-resistant key exchange and digital signatures to protect connections against future computing threats. It distinguishes itself through security hardening measures, such as memory-locked secret storage to prevent keys from being swapped to disk and timing-attack mitiga
Basic implementations of standard cryptography algorithms, like AES and SHA-1.
