Sorry, that is a topic related to AES Rijndael, which is a topic we are not allowed to give code for on this forum due to USA legal restrictions.

Is a subfunction of the encryption method a " working code for > 64 bit encryption " already? As far as I can see, we are allowed to post the code, but TMW is forced to delete it as soon as possible.
