About
This library is heavily inspired by hash-wasm. It only includes the Argon2 algorithm and can run on Vercel Edge functions and Cloudflare Workers.
Hashing passwords with Argon2
Parameters
hasingParams.ts
The recommended process for choosing the parameters can be found here.
export default {
parallelism: 1,
iterations: 256,
memorySize: 512, // use 512KB memory
hashLength: 32, // output size = 32 bytes
outputType: 'encoded', // return standard encoded string containing parameters needed to verify the key
};Usage on standard Node and Bun environments
import params from './hasingParams';
import { argon2id, argon2Verify } from 'argon2-wasm-edge';
async function run() {
// salt is a buffer containing random bytes
const salt = new Uint8Array(16);
window.crypto.getRandomValues(salt);
const key = await argon2id({ ...params, password: 'pass', salt });
console.log('Derived key:', key);
const isValid = await argon2Verify({
password: 'pass',
hash: key,
});
console.log(isValid ? 'Valid password' : 'Invalid password');
}
