I've been doing a little bit of reading lately on cryptography and 'secret writing' systems, particularly historical examples. I'm looking more at alphabetic substitutions and transpositions, human (de)codeable, not complex mathematical algorithims. Of course, both could be applied. Anyways, it has occurred to me that ASCII pictures would be an ideal method for concealing ciphered text. An innocuous usenet posting or signature line picture could easily contain an enciphered message. I'm going to try to come up with a few examples in the next while (and hopefully some perl scripts), but in the meantime, has anyone else done anything in this area? Any URLs of interest?
