About

We maintain dozens of popular crates which provide pure Rust implementations of cryptographic algorithms, including the following:

Asymmetric encryption: elliptic-curves, ml-kem, rsa
Cryptographic encoding formats: const-oid, der, pem-rfc7468, pkcs8, ssh-key, x509-cert
Digital signatures: ecdsa, ed25519, ml-dsa, rsa
Elliptic curves: k256 (secp256k1), p256, p384
Hash functions: blake2, sha2, sha3
Key derivation functions: hkdf, pbkdf2
Message authentication codes: hmac
Password hashes: argon2, pbkdf2, scrypt, yescrypt
Sponge functions: ascon, keccak
Symmetric encryption: aes-gcm, aes-gcm-siv, chacha20poly1305
Traits: aead, cipher,digest, password-hash, signature
