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.
bcrypt
Battle-tested password hashing for Node.js using the adaptive bcrypt algorithm.
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
libsodium-wrappers
WebAssembly build of libsodium with hand-friendly JavaScript wrappers for encryption, signing, hashing, and key exchange.
react-native-get-random-values
A native polyfill that implements crypto.getRandomValues() for React Native so libraries like uuid work without modification.
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.
hash-wasm
Lightning-fast hash and password-derivation functions using hand-tuned WebAssembly binaries
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.
js-md5
A fast, dependency-free MD5 hash function for JavaScript with UTF-8 support
sha.js
A pure JavaScript, streamable implementation of the SHA family of hash functions with a Node-crypto-like API.
totp-rs
RFC 6238-compliant TOTP two-factor authentication for Rust
PKIjs
A pure TypeScript library implementing the core formats and protocols of public-key infrastructure, built entirely on the WebCrypto API with no native bindings or plug-ins.
openidconnect-rs
A strongly-typed, extensible Rust implementation of the OpenID Connect protocol for building relying-party authentication and OIDC provider integrations.
crypto-random-string
Generate cryptographically strong random strings for IDs, slugs, salts, and secrets
totp-generator
Generate TOTP one-time passcodes from a secret key using the native Web Crypto API, with a pure-JS fallback.
hawk
JavaScript implementation of the Hawk HTTP holder-of-key authentication scheme
webauthn-rs
A Rust implementation of the WebAuthn Relying Party protocol for passkey and passwordless authentication.
opaque-ke
Rust implementation of the OPAQUE augmented password-authenticated key exchange protocol
ASN1.js
A pure JavaScript/TypeScript library for encoding and decoding ASN.1 BER/DER data, the foundation of X.509 certificates and PKI.
xxhashjs
Pure JavaScript implementation of the xxHash algorithm, delivering fast 32-bit and 64-bit non-cryptographic hashing.
jwt-simple
A fast, safe-by-default Rust library for creating and verifying JWT and JWE tokens across every major signing and encryption algorithm.
Biscuit-Auth
Rust implementation of Biscuit — a decentralized authorization token with offline attenuation and a Datalog policy language.
