sha2
Pure Rust implementation of the SHA-2 hash function family (SHA-224/256/384/512) with hardware-accelerated backends.
cryptography
The standard cryptographic library for Python, pairing safe high-level recipes with low-level primitives backed by Rust and OpenSSL.
core-js
Modular standard library and polyfills for JavaScript, from ECMAScript features to proposals and web standards.
rustls
A modern, memory-safe TLS library for Rust with no unsafe code and no legacy crypto by default.
forge
A native, pure-JavaScript implementation of TLS and PKI cryptography for building crypto-based Node.js and browser apps.
curve25519-dalek
Pure-Rust group arithmetic over Curve25519 and Ristretto255
js-sha256
A fast, zero-dependency SHA-256/SHA-224 hashing library for JavaScript with built-in UTF-8 support and HMAC.
libsodium-wrappers
WebAssembly build of libsodium with hand-friendly JavaScript wrappers for encryption, signing, hashing, and key exchange.
noble-hashes
Audited, zero-dependency JS/TS implementation of SHA2, SHA3, BLAKE, HMAC, HKDF, PBKDF2, Scrypt and Argon2 that tree-shakes down to a few kilobytes per hash.
tweetnacl-js
A JavaScript port of the audited TweetNaCl cryptographic library, providing public-key and secret-key encryption, signing, and hashing for Node.js and browsers.
secrecy
Rust wrapper types that keep secrets out of logs, debug output, and Clone/Copy, and securely wipe them from memory on drop
phpseclib
Pure-PHP implementations of SSH2, SFTP, X.509, RSA, AES, and dozens of other cryptographic primitives
ring
Safe, fast, small cryptographic primitives for Rust, built on verified assembly from BoringSSL
jsrsasign
Pure JavaScript cryptography library for RSA/ECDSA/DSA signing, X.509 certificates, ASN.1, JWS/JWT, and CMS.
pyOpenSSL
A Python wrapper around the OpenSSL library for TLS connections and certificate handling
