- Once you get past doing those little substitution ciphers
- in the back of crossword magazines, what becomes interesting
- is algorithms. For a method to be used, it has to be
- published (knowingly or otherwise, since dissassembling
- programs is duck soup these days). For an encryption to
- present a challenge, it has to be robust under plaintext
- attack when the attacker has a copy of the mechanism.
-
- Whether he is just being cute, or thinks he has patent
- possibilities, the sad fact is that the only way Erik's friend
- will get anyone's attention is by publishing his method.
-
- There may be a way out: He can claim that the method is the
- key. In that case he should publish the technique used to
- generate a very large number of cryptographically different
- methods. I've already proposed something very much like that
- in this group, which (strangely|sadly) didn't stimulate any
- discussion.

- Cheers,
