Cryptography & Hashing Packages
Cryptographic primitives, hashing, and encryption libraries for securing data at rest and in transit across your application stack.
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.
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
argon2
A pure-Rust implementation of the Argon2 password hashing function
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.
argon2-cffi
Secure, high-level password hashing for Python using Argon2
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.
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
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.
@node-rs/argon2
Native Rust binding for Argon2 password hashing in Node.js
aHash
A fast, DOS-resistant, AES-accelerated non-cryptographic hasher purpose-built for in-memory HashMaps
js-md5
A fast, dependency-free MD5 hash function for JavaScript with UTF-8 support
TwoX-Hash
A pure Rust implementation of the xxHash and XXH3 non-cryptographic hashing algorithms.
string-hash
A tiny, dependency-free string hashing function for fast, non-cryptographic hash generation in JavaScript.
sha.js
A pure JavaScript, streamable implementation of the SHA family of hash functions with a Node-crypto-like API.
argon2-cffi-bindings
Low-level CFFI bindings that compile the official Argon2 C library for direct use from Python.
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.
crypto-random-string
Generate cryptographically strong random strings for IDs, slugs, salts, and secrets
pwdlib
Modern password hashing for Python with Argon2 and bcrypt and a simple hash and verify API.
crc32c
Hardware-accelerated CRC-32C checksums for Rust, with automatic SSE4.2/ARM CRC detection and a pure-software fallback.
