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. Jim
