Hi Thomas,

Below are the encoder/decoder functions I've extracted from the Rot13 
Encoder/Decoder Firefox extension, I can send you the whole JS file if 
you'd like.

The extension author credits http://tools.geht.net/rot13.html for the 
original code though, and it's publicly available at that URL (view the 
page source code) so check there too.

That should give you a starting point, let me know if you get stuck,

Cheers
Karen


 rot13EncoderInit: function() {
       var map = new Array();
       var s   = "abcdefghijklmnopqrstuvwxyz";
       for (i=0; i<s.length; i++)
     map[s.charAt(i)]= s.charAt((i+13)%26);
       for (i=0; i<s.length; i++)
     map[s.charAt(i).toUpperCase()]= s.charAt((i+13)%26).toUpperCase();
       return map;
   },
  decode: function (text) {
      // rot13 decode function taken from Valentin Hilbig

      var src = new String(text);
      var rot13map;
      var s;
      var i;
      rot13map=rot13.rot13EncoderInit();
      s = "";
      for (i=0; i<src.length; i++) {
      var b = src.charAt(i);
      s+= (b>='A' && b<='Z' || b>='a' && b<='z' ? rot13map[b] : b);
      }
      return s;
  },
