s2n-tls is a C99 implementation of the TLS/SSL protocols designed to be simple, small, fast, and security-focused, maintained by AWS. It provides a C library with Rust bindings for adding encrypted TLS connections to applications and services.

Use cases

  • add TLS encryption to a C or Rust application
  • embed a small fast TLS library in a service
  • replace OpenSSL for TLS handshakes
  • implement secure client and server connections
  • audit a minimal TLS implementation for security review

When to choose

  • you need a compact, auditable TLS library in C or Rust
  • you want a security-focused alternative to OpenSSL for TLS
  • you're building AWS-style services needing lightweight TLS

When to avoid

  • you need a full-featured general-purpose crypto toolkit beyond TLS
  • you need high-level language bindings other than Rust
  • you want a turnkey HTTPS server rather than a library
