The system must not require … WebKerckhoffs' surviving principle nr. 2 (of initially six design principles for military ciphers) says nothing else than that you have to look at the security of your crypto under the aspects of "the enemy knows the algorithm" and maybe even "the enemy carries the message".

One problem with encoding schemes is that they rely on humanly-held secrets such as "dictionaries" which disclose for example, the secret meaning of words. Steganographic-like dictionaries, once revealed, permanently compromise a corresponding encoding system.

"WebJun 19, 2012 · The idea is that if any part of a cryptosystem (except the individual secret key) has to be kept secret then the cryptosystem is not secure. That's because if the simple act of disclosing some detail of the system were to make it suddenly insecure then you've got a problem on your hands. " - Cipher principles
