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
