Rustls is a modern TLS library written in Rust implementing TLS 1.2 and TLS 1.3 for both clients and servers. It provides secure defaults with no unsafe features or obsolete cryptography, and supports pluggable cryptography providers.

Use cases

• add TLS encryption to a Rust server
• make HTTPS requests from Rust with a safe TLS stack
• implement TLS 1.3 client and server connections
• replace OpenSSL with a memory-safe TLS library
• customize cryptographic primitives via a crypto provider
• secure microservice communication in Rust

When to choose

• you need a memory-safe, modern TLS implementation in Rust
• you want secure defaults without configuration
• you need pluggable cryptography providers for compliance or portability
• you are building Rust network services or clients

When to avoid

• you need legacy protocols like SSLv3 or TLS 1.0/1.1
• you require FIPS-certified cryptography out of the box
• your stack is not Rust and you cannot use a Rust library
