Category1
Sort:Used by Most Apps
cryptography
The standard cryptographic library for Python, pairing safe high-level recipes with low-level primitives backed by Rust and OpenSSL.
bcrypt.js
A zero-dependency, pure JavaScript implementation of bcrypt for hashing and verifying passwords in Node.js and the browser.
PyJWT
A Python implementation of RFC 7519 for encoding, decoding, and verifying JSON Web Tokens.
forge
A native, pure-JavaScript implementation of TLS and PKI cryptography for building crypto-based Node.js and browser apps.
bcrypt (Python)
A Python library for secure password hashing using the bcrypt algorithm with an adjustable work factor
itsdangerous
A small Python toolkit for cryptographically signing data so you can trust it hasn't been tampered with when it comes back from an untrusted client.
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.
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.
hash-wasm
Lightning-fast hash and password-derivation functions using hand-tuned WebAssembly binaries
pyOpenSSL
A Python wrapper around the OpenSSL library for TLS connections and certificate handling
JavaScript-MD5
A zero-dependency JavaScript MD5 and HMAC-MD5 hashing implementation that runs identically in Node.js, browsers, and AMD module loaders.
PyOTP
Python library for generating and verifying TOTP/HOTP one-time passwords for 2FA
speakeasy
A Node.js library for generating and verifying RFC 4226 (HOTP) and RFC 6238 (TOTP) one-time passcodes for two-factor authentication.
pycryptodome
A self-contained, low-level Python library of cryptographic primitives — ciphers, hashes, MACs, and public-key algorithms — with no OpenSSL dependency.
hvac
Python client library for HashiCorp Vault's secrets, authentication, and system-backend REST APIs.
service-identity
Verifies that a pyOpenSSL or cryptography TLS certificate is genuinely valid for the hostname, IP, or SRV name you intended to connect to.
js-md5
A fast, dependency-free MD5 hash function for JavaScript with UTF-8 support
python-rsa
Pure-Python RSA library for key generation, PKCS#1 encryption, decryption, signing, and verification, with no C extensions required.
xxhash
Fast Python bindings for the xxHash non-cryptographic hashing algorithm
asn1crypto
A fast, pure Python library for parsing and serializing ASN.1 structures with a pythonic, high-performance API.
sha.js
A pure JavaScript, streamable implementation of the SHA family of hash functions with a Node-crypto-like API.
