ring is a Rust library providing safe, fast cryptographic primitives (hashing, AEAD, signatures, key agreement) built largely on BoringSSL's C and assembly code. The author explicitly describes it as an experiment and discourages general-purpose dependence.

Use cases

• encrypt and decrypt data with AES-GCM or ChaCha20-Poly1305 in Rust
• generate and verify Ed25519 or RSA signatures
• compute SHA-256 digests and HMACs
• perform ECDH key agreement for TLS-like protocols
• generate cryptographically secure random values

When to choose

• you need a Rust crypto library with a misuse-resistant API and BoringSSL-derived primitives
• you are already using Rust TLS stacks like rustls that depend on it
• you want constant-time, assembly-optimized crypto on common platforms

When to avoid

• you need a formally supported, general-purpose crypto library with long-term stability guarantees
• you need a broad feature set like certificates, TLS protocol handling, or X.509 parsing
• you require side-channel guarantees beyond what the project documents in SIDE-CHANNELS.md
