I'm sorry, I don't think I said that very clearly. CipherSaber discusses computer implementations for RC4. I'm attempting to construct a paper-and-pencil implementation of a modified version of RC4, while still keeping the cipher secure against computer cryptanalytic attacks. A description of the modified RC4 (and a brief description of the goal), as I mentioned earlier, is available here: http://www.mindflare.com/cipher/ Thanks for your time, Jeremy
