Some code snippets to generate SHA hash from a entered password then check that hash against another hash.

HTML

<script src="http://www.bichlmeier.info/sha256.js"></script>

<div class="input-prepend">
    <span class="add-on">To Be Hashed</span>
    <input class="span11" id="input" type="text"></input>
    <input class="span11" id="input2" type="text"></input>
</div>

JavaScript

$("input").keyup( function () {
    var value = $(this).val();
    console.log(sha256_digest(value))
    $("#input2").val(sha256_digest(value).toUpperCase());
}).keyup();
