Hi all,

I've copyed this code from someone else and trying to get it to work...

public static String getKeyedDigest(String input, String key) {
:
:
           MessageDigest md = MessageDigest.getInstance("MD5");
           md.update(input.getBytes());
           digest = md.digest(key.getBytes());
           dstr = new BigInteger(1, digest).toString(16);
           /* this is important, toString leaves out initial 0 */
           if (dstr.length() % 2 > 0)
               dstr = "0" + dstr;
       } catch (NoSuchAlgorithmException ex) {
           ex.printStackTrace();
       }

Unfortunately it retuns the correct check ... but not the leading
zero's which I need.

What it returned: 96f07821d958764gcc1fcd76d12358
expected:       0096f07821d958764gcc1fcd76d12358

or

What it returned: 0454abc257b09547a8a7f87c785328
expected:       000454abc257b09547a8a7f87c785328

TIA
