Packages in Cryptography & Hashing
Kind
Sort:Used by Most Apps
bcrypt.js
A zero-dependency, pure JavaScript implementation of bcrypt for hashing and verifying passwords in Node.js and the browser.
crypto-js
A JavaScript library of crypto standards - hashing, HMAC, PBKDF2, and symmetric ciphers for Node.js and the browser.
bcrypt
Battle-tested password hashing for Node.js using the adaptive bcrypt algorithm.
hmac
Generic, pure-Rust implementation of Hash-based Message Authentication Code (HMAC)
forge
A native, pure-JavaScript implementation of TLS and PKI cryptography for building crypto-based Node.js and browser apps.
OTPAuth
HOTP and TOTP one-time password library for Node.js, Deno, Bun, and browsers
curve25519-dalek
Pure-Rust group arithmetic over Curve25519 and Ristretto255
argon2
A pure-Rust implementation of the Argon2 password hashing function
rust-openssl
Safe, idiomatic Rust bindings to OpenSSL
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.
react-native-get-random-values
A native polyfill that implements crypto.getRandomValues() for React Native so libraries like uuid work without modification.
hkdf
Pure Rust, no-std implementation of the HMAC-based Extract-and-Expand Key Derivation Function
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.
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.
argon2
Node.js bindings to the reference Argon2 password hashing implementation
hash-wasm
Lightning-fast hash and password-derivation functions using hand-tuned WebAssembly binaries
pkcs8
Pure Rust implementation of PKCS#8 private key encoding and decoding
subtle
Pure-Rust traits and utilities for writing constant-time cryptographic code that resists timing side-channel attacks.
JavaScript-MD5
A zero-dependency JavaScript MD5 and HMAC-MD5 hashing implementation that runs identically in Node.js, browsers, and AMD module loaders.
speakeasy
A Node.js library for generating and verifying RFC 4226 (HOTP) and RFC 6238 (TOTP) one-time passcodes for two-factor authentication.
rsa
Pure Rust implementation of RSA encryption, signing, and key handling
