Below is the encode function... I seem to have forgoten the decode function... oops.

  <input type="button" onclick="doEncode()" value="encode"/><br/><br/>
  <div id="outputContainer" style="display:none;">
   <span style="display: inline-block; width: 120px;">Encoded:</span><span id="outputEnc"></span><br/>
