 # pbkdf2

 [![NPM Package](https://img.shields.io/npm/v/pbkdf2.svg?style=flat-square)](https://www.npmjs.org/package/pbkdf2)
 [![Build Status](https://img.shields.io/travis/crypto-browserify/pbkdf2.svg?branch=master&style=flat-square)](https://travis-ci.org/crypto-browserify/pbkdf2)
 [![Dependency status](https://img.shields.io/david/crypto-browserify/pbkdf2.svg?style=flat-square)](https://david-dm.org/crypto-browserify/pbkdf2#info=dependencies)

 This library provides the functionality of PBKDF2 with the ability to use any supported hashing algorithm returned from `crypto.getHashes()`


 ## Usage

 ```js
 var pbkdf2 = require('pbkdf2')
 var derivedKey = pbkdf2.pbkdf2Sync('password', 'salt', 1, 32, 'sha512')

 ...
 ```

 For more information on the API,  please see the relevant [Node documentation](https://nodejs.org/api/crypto.html#crypto_crypto_pbkdf2_password_salt_iterations_keylen_digest_callback).

 For high performance,  use the `async` variant (`pbkdf2.pbkdf2`),  not `pbkdf2.pbkdf2Sync`,  this variant has the oppurtunity to use `window.crypto.subtle` when browserified.


 ## Credits

 This module is a derivative of [cryptocoinjs/pbkdf2-sha256](https://github.com/cryptocoinjs/pbkdf2-sha256/), so thanks to [JP Richardson](https://github.com/jprichardson/) for laying the ground work.

 Thank you to [FangDun Cai](https://github.com/fundon) for donating the package name on npm, if you're looking for his previous module it is located at [fundon/pbkdf2](https://github.com/fundon/pbkdf2).
