PBKDF2 (v34)

Revision 34 of this benchmark created by Calvin Metcalf on

Description

PBKDF2 (hmacSHA1) for JavaScript

Compares the PBKDF2 methods of the Stanford Javascript Crypto Library with the ones from CryptoJS and Anandam.

Setup

var hmacSHA1 = function(key) {
          var hasher = new sjcl.misc.hmac(key, sjcl.hash.sha1);
          this.encrypt = function() {
            return hasher.encrypt.apply(hasher, arguments);
          };
          };
    
      // from http://stackoverflow.com/questions/3745666/
    
      function hex2a(hex) {
        var str = '';
        for (var i = 0; i < hex.length; i += 2)
        str += String.fromCharCode(parseInt(hex.substr(i, 2), 16));
        return str;
      }
      var iterations = 500;
      var password = 'password';
      var hexSalt = '29EEE7AA9C0E9315';
      var keySizeBits = 256;
      var sjclSalt = sjcl.codec.hex.toBits(hexSalt);
      var cryptoSalt = CryptoJS.enc.Hex.parse(hexSalt);
      var anandamSalt = hex2a(hexSalt);
      var browserifySalt = new browserifyCrypto.Buffer(hexSalt, 'hex');
