RE: Cryptography | H-4605

well Umm,
i didn't expect any kind of discussion like that from my posts, but if you asking then we are not so far from that era but in the present era lots of Secure Cryptographic Devices(SCDs) or Integrated Circuit payment cards are the best example of your question.
but it's not over yet in my opinion there must be some cipher machines which are kept by secret divisions of government like our past days.
