FW: [Cryptix-users] Automatic padding doesn't seem to work for Rijndael (in plain text)

[<nbr...@to...>]

Hi,

I'm using this stuff for the first time, but am bemused by the
following:

The javadoc for xjava.security.Cipher states that all versions of
crypt() automatically pad/unpad as necessary. =20

But a simple test case for Rijndael:

      String message =3D "Dennis eats worms.";
      Cipher cipher =3D Cipher.getInstance(algorithm);
      cipher.initEncrypt(new RawSecretKey(algorithm, key));=20
      byte[] encryptedMessage =3D cipher.crypt(message.getBytes());
      cipher.initDecrypt(new RawSecretKey(algorithm, key));
      byte[] unencryptedMessage =3D cipher.crypt(encryptedMessage);
      System.out.println("message=3D" + new String(unencryptedMessage));=


Throws the following exception:

Exception in thread "main" xjava.security.IllegalBlockSizeException:
Rijndael: Non-padding cipher in ENCRYPT state with an incomplete final
block
        at xjava.security.Cipher.updateInternal(Cipher.java:1264)
        at xjava.security.Cipher.crypt(Cipher.java:1046)
        at xjava.security.Cipher.crypt(Cipher.java:1011)
        at com.touchcorp.test.Encrypt.main(Encrypt.java:46)

Either the javadoc or the code appears to be wrong.

Help?
