Native Rust binding for Argon2 password hashing in Node.js
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.
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.
jws
