- True for DES (and indeed most ciphers), but what about intrinsically much
- simpler systems like RSA? With suitable maths software, the distinction
- between a 'human-orientated description' and a 'computer program' becomes
- a very fine one.
-
- Indeed. I suppose that Tanenbaum's book "Computer Networks" must now
- also be classed as munitions since the first edition included Pascal
- source code for a DES implementation.
