CryptoJS PBKDF2 hashing with javascript. This could be used for a simple, not high security, password auth.

crypto-pbkdf2-auth-example.js

// bower install crypto-js
// Add to scripts to html file
//   <script src="bower_components/crypto-js/crypto-js.js"></script>
//   <script src="bower_components/crypto-js/pbkdf2.js"></script>

function auth(password) {
  // Make a salt with CryptoJS.lib.WordArray.random(128/8);
  var salt = 'your salt'; // CryptoJS.lib.WordArray.random(128/8);
  
  // 1000 iterations takes a couple seconds in the browser. Wouldn't want to go much higher if this is a browser implementation
  var iterations = 1000;
  
  // make your own hash if you don't know this one
  var matchHash = '98a24959e05c77656f6308a541d2dd922c4dd9e2b6b75d49509e31c42fb4a4ba681ad5408ede32a523139bb38f3db5ea9f867f2cb4512137018296eeea000d36';
  
  var userHash = CryptoJS.PBKDF2(password, salt, { keySize: 512/32, iterations: iterations });
  return userHash.toString() === matchHash;
}

@billyxs Can I know why the length of 'matchHash' variable is 128 while you mentioned the keySize is 512. Is it like an upper limit?
