The P-Box in Cryptography

[@jasonsachinger3276]

You mentioned that the example @27:04 came from a textbook. What textbook is that?

[@Jim-vr2lx]

It's from a book called "Cryptography and Network Security" that was published as a PDF from Cleveland State University. It comes and goes from the Internet (and Cleveland State doesn't host it anymore) so if you find a copy, save it. Try searching google for "Data Encryption Standard (DES) - Cleveland State University pdf". Then scroll through the search results for some archive site. Also, another good (free) book with the same detailed info is called "Cryptography-and-network-security-principles-and-practice.pdf".
