Audited & minimal JS implementation of hash functions, MACs and KDFs.

✅ .NET crypto done right. Professionally audited.

A Java standalone implementation of the bcrypt password hash function. Based on the Blowfish cipher it is the default password hash algorithm for OpenBSD and other systems including some Linux distributions. Includes a CLI Tool.

Argon2 library compiled for browser runtime

Library for securely hashing passwords

Password-based key derivation function and password hashing scheme building upon scrypt

Fast "async" scrypt implementation in JavaScript

A Hybrid Public Key Encryption (HPKE) module built on top of Web Cryptography API.

A fast, lightweight, and full duplex secure end-to-end encryption protocol based on ECDHE

A standalone Java 7 implementation of HMAC-based key derivation function (HKDF) defined in RFC 5869 first described by Hugo Krawczyk. HKDF follows the "extract-then-expand" paradigm which is compatible to NIST 800-56C Rev. 1 two step KDF

A strong and customizable password generator made with python3!

Password based key derivation functions from PKCS#5, RFC 2898
