in reply to Substitution cipher or keyboard layout demo
I know this is a moderately older thread, but I was catching up on CUFP and after reading this, it seems remarkably similar to the Enigma encoding machine that the German's used in WWII -- you press one key and another one actually registers... it wouldn't be terribly difficult to create random mappings based on some hash... of course you'd need a decoder as well, but that would be entirely software based since they wouldn't use the keyboard to read it.
Very cool idea though. I've never used a Dvorak keyboard, but I might check them out sometime.
