I think we need something somewhere that discusses the general notion that systems which require something large, rather than just a small key, to be kept secret are a bad idea. This applies to one-time pads and to codes needing a codebook, and is one way to think about Kerckhoffs'_Principle; there may be applications I have not thought of.

Should that text go in Cryptography? Or here? Or where? Sandy Harris 03:57, 5 February 2010 (UTC)
