argon2-wasm

https://github.com/P-H-C/phc-winner-argon2 compiled to base64,It works in both the NodeJS environment and the browser environment.

This project does not need to reference annoying ".wasm" files when used under the browser.

usage

install:

npm install argon2-wasm-pro

Add script:

const argon2 = require('argon2-wasm-pro');

Get hash:

argon2
  .hash({ pass: 'password', salt: 'somesalt' })
  .then(h => console.log(h.hash, h.hashHex, h.encoded))
  .catch(e => console.error(e.message, e.code));

Verify the encoded hash:

argon2
  .verify({ pass: 'password', encoded: 'enc-hash' })
  .then(() => console.log('OK'))
  .catch(e => console.error(e.message, e.code));

Bring your own bundler and promise polyfill. Other parameters:

argon2
  .hash({
    // required
    pass: 'password',
    salt: 'salt',
    // optional
    time: 1, // the number of iterations
    mem: 1024, // used memory, in KiB
    hashLen: 24, // desired hash length
    parallelism: 1, // desired parallelism (will be computed in parallel only for PNaCl)
    type: argon2.ArgonType.Argon2d, // or argon2.ArgonType.Argon2i
    distPath: '' // asm.js script location, without trailing slash
  })
  // result
  .then(res => {
    res.hash; // hash as Uint8Array
    res.hashHex; // hash as hex-string
    res.encoded; // encoded hash, as required by argon2
  })
  // or error
  .catch(err => {
    err.message; // error message as string, if available
    err.code; // numeric error code
  });
