Raymon, what you are posting is totally meaningless. Asking Bletchley Park (see Google) is perhaps a better option for you.

You could be looking at Data, you could be looking at Machine Code, you could be looking at a combination of both, it may be encrypted, it might not be. It may be compressed, it might not be. It might be combinations of everything.

For example, you could be looking at the interchange of Data between a Smart-Card and an ATM terminal, or between a Smart-Card and a TV Subscription Receiver.

There are hundreds of different encryption systems around the world, and hundreds of different compression alogrythms... without knowing which one, and without knowing what HARDWARE is involved (because if there is any embedded Machine Code it will be different for each family of chips), and without knowing the APPLICATION CONCERNED, it is a COMPLETE WASTE OF TIME.

And, if it is encrypted Data, you are obviously trying to gain access to something that you are not supposed to. In effect you could be asking this forum to help you commit Copyright or other Intellectual Property theft. The guy that cracked the code for Series 7 of the Sky Satellite Card got 4 years jail! Let's not put this forum or any contributor to it in that position.
