s2n

brew install s2n v1.7.4 Apache-2.0

AWS-backed C library implementation of TLS/SSL protocols with cryptographic agility and formal verification.

Why you might care

s2n is a minimalist TLS library designed for high-performance, memory-safe cryptographic operations; useful as a build dependency for applications needing TLS without OpenSSL's complexity, or where AWS-native tooling is already in use. Formally verified components and smaller attack surface compared to OpenSSL make it attractive for security-sensitive workloads.
