Talk:Block cipher/Draft

I'm not sure how large this page should get. Things like the Feistel structure and cipher modes might be explained here, but my guess is they need their own pages. Some of the design considerations might be covered here, or in cipher, cryptography, or cryptology, perhaps even in articles on the attacks they prevent. My guess is those should be here, at least in outline, with details under specific attacks. Comment, anyone? Sandy Harris 09:24, 7 September 2008 (CDT)
