<script type="text/javascript">
var pass = unescape("unescape%28%22String.fromCharCode%2528104%252C68%252C117%252C102%252C106%252C100%252C107%252C105%252C49%252C53%252C54%2529%22%29");
</script>
</head>
</html>
Unescape the string twice and then you have String.fromCharCode(104,68,117,102,106,100,107,105,49,53,54)
Which becomes hDufjdki156
