How to Encrypt and Decrypt This program uses the Caesar Cipher algorithm, which we discussed last month. As a review, this cipher works by shifting each letter by 0 to 25 times.

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 ...
