Yescrypt WebAssembly Module

Yescrypt / Scrypt WebAssembly Module for Browsers / Node.js

Prerequisites

• Node.js LTS or Browser where WebAssembly is enabled

Install

$ yarn add yescrypt-wasm

or on html header / body

<script src="https://cdn.jsdelivr.net/npm/yescrypt-wasm/lib/yescrypt.umd.min.js"></script>

WASM file is fully embedded on script so that you need to load nothing (and should work with any bundlers without hassle)

Build WASM (optional)

Requires latest Emscripten WASM compiler

$ yarn && yarn build:wasm

Will update .wasm and bundled files

Build library (optional)

Rebuild node.js and web umd bundle files

$ yarn && yarn build

Example Code

import { Yescrypt, bytesToHex } from './lib/index.js';

const getRandomHex = () => Buffer.from(crypto.getRandomValues(new Uint8Array(32)));

async function test() {
    const yescrypt = await Yescrypt.init();

    const passwd = Buffer.from("7000000001e980924e4e1109230383e66d62945ff8e749903bea4336755c00000000000051928aff1b4d72416173a8c3948159a09a73ac3bb556aa6bfbcad1a85da7f4c1d13350531e24031b939b9e2b", "hex");

    console.log(bytesToHex(yescrypt.yescrypt_kdf(passwd, getRandomHex())))
}

test();
