The value is the cipher key. For example, the code IBDLBEBZ is encrypted with a Caesar Cipher. It doesn’t take very much to see that a shift of “1” would reveal HACKADAY.

Bernard claims Lukas uses a Ceaser shift cipher to decode the meaning of Salvador Quinn's cryptic message, making it hard not to wonder what it means.

Caesar Ciphers are very simple methods of encryption because the work by shifting the alphabet over a few characters and matching up the letters (see the picture above)—in fact, if you've ever ...
