Rust bindings to the OpenSSL cryptography and TLS library, exposing its APIs (certificates, keys, hashing, SSL/TLS connections) to Rust programs. It is the de facto standard crate for using OpenSSL from Rust, published on crates.io as `openssl`.

Use cases

• use openssl from rust
• establish tls connections in a rust program
• generate and manage x509 certificates in rust
• hash and sign data with openssl in rust
• wrap an existing c openssl codebase in rust

When to choose

• you need OpenSSL's specific algorithms or FIPS compliance in Rust
• you must interoperate with systems requiring OpenSSL
• you want the most mature, widely used TLS/crypto binding for Rust

When to avoid

• you want a pure-Rust crypto stack with no C dependency (consider rustls/ring)
• you cannot build or link the OpenSSL C library in your environment
• you only need basic hashing or AEAD available in pure-Rust crates
