pbkdf2-sha512 is a JavaScript implementation of PBKDF2 using the SHA512 HMAC. It's fully compatible with Node.js and the browser (via Browserify).
This is useful for the Scrypt algorithm.
Why not just use the Node.js pbkdf2 function? The Node.js pbkdf2 function uses the sha1 algorithm and not the sha512 algorithm for its pseudorandom function. This will change when Node v0.12 is released. Until then, this is the next best option.
npm install --save pbkdf2-sha512
var pbkdf2 = require('pbkdf2-sha512');
var key = 'passwd';
var salt = new Buffer('salt');
var res = pbkdf2(key, salt, 1, 64);
console.log(res.toString('hex')) // => 55ac046e56e3089fec1691c22544b605f94185216dde0465e68b9d57c20dacbc49ca9cccf179b645991664b39d77ef317c71b845b1e30bd509112041d3a19783To use in the browser, clone the repo and then download Browserify:
npm install -g browserify
run:
browserify --standalone pbdkf2 < lib/pbkdf2.js > pbdkf2.bundle.js
then include pbdkf2.bundle.js in your <script> tag in your html.
If you want to test the algorithm, clone the git repo. Then run npm install --development to install all of the dependencies.
run:
make test-node
run:
make test-browser
after you're finished, you can kill the test browser server (test-browser.js) by running:
make kill

- https://code.google.com/p/crypto-js/source/browse/tags/3.1.2/src/pbkdf2.js (CryptoJS)
Why didn't I use either one of these? They're not Node.js optimized. They also don't use native types, so they'll be slower in the browser.
