Everything you need to know can be found in org.picketbox.datasource.security.SecureIdentityLoginModule

Isn't open source wonderful?

        String value = null;

        if (args.length < 0) {

          System.out.println("Necessary arguments Not passed,Please Pass the Password To Decrypt");

        } else {

          value = args[0].toString().trim();

        throws NoSuchPaddingException, NoSuchAlgorithmException, InvalidKeyException, BadPaddingException, IllegalBlockSizeException

      {

        byte[] kbytes = "jaas is the way".getBytes();

        SecretKeySpec key = new SecretKeySpec(kbytes, "Blowfish");

        BigInteger n = new BigInteger(secret, 16);

        byte[] encoding = n.toByteArray();

        Cipher cipher = Cipher.getInstance("Blowfish");

        cipher.init(2, key);

        byte[] decode = cipher.doFinal(encoding);

        return new String(decode).toCharArray();

      }
