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.

If you have to write down a password, or some other sensitive information, you can use a Caesar Cipher to quickly encode and decode that message on your own.

As discussed above, however, although the Caesar cipher provides a great introduction to cryptography, in the computer age it is no longer a secure way to send encrypted communications electronically.
