Universal Module for Password-based Key Derivation Function (PBKDF) in JavaScript

npm version Dependencies License: MIT

WARNING: At this time this solution should be considered suitable for research and experimentation, further code and security review is needed before utilization in a production application.

Introduction and Overview

This library is designed to 'universally' provide PBKDF (Password-based Key Derivation Function) functions, i.e., it works both on most modern browsers and on Node.js just by importing from NPM/source code. This key utility library provides both PBKDF1 and PBKDF2 specified in PKCS#5 v2.1 (RFC8018).

Installation

At your project directory, do either one of the following.

  • From npm/yarn:
    $ npm install --save js-crypto-pbkdf // npm
    $ yarn add js-crypto-pbkdf // yarn
  • From GitHub:
    $ git clone https://github.com/junkurihara/jscu.git
    cd js-crypto-utils/packages/js-crypto-pbkdf
    & yarn build

Then you should import the package as follows.

import pbkdf from 'js-crypto-pbkdf'; // for npm
import pbkdf from 'path/to/js-crypto-pbkdf/dist/index.js'; // for github

The bundled file is also given as js-crypto-pbkdf/dist/jscpbkdf.bundle.js for a use case where the module is imported as a window.jscpbkdf object via script tags.

Usage

PBKDF2

See RFC8018 Section 5.2 for detailed specification.

const password = 'password'; // string or Uint8Array
const salt = ...; // Uint8Array
const iterationCount = 2048;
const derivedKeyLen = 32;
const hash = 'SHA-256'; // 'SHA-384', 'SHA-512', 'SHA-1' or 'MD5' 
 
pbkdf.pbkdf2(
  password,
  salt,
  iterationCount,
  derivedKeyLen,
  hash
).then( (key) => {
  // now you get the derived key of intended length
});

PBKDF1

See RFC8018 Section 5.1 for detailed specification.

const password = 'password'; // string or Uint8Array
const salt = ...; // Uint8Array
const iterationCount = 2048;
const derivedKeyLen = 32;
const hash = 'SHA-256'; // 'SHA-384', 'SHA-512', 'SHA-1' or 'MD5' 
 
pbkdf.pbkdf1(
  password,
  salt,
  iterationCount,
  derivedKeyLen,
  hash
).then( (key) => {
  // now you get the derived key of intended length
});
