Currently, technology is more accessible than ever. We now have networks, both private and public, that convey sensitive and personal information between many users. For millenium, people have tried to send messages in a secure manner using encryption.

Data encryption encrypts a message by translating it to a secret code, called a cipher text. The receiver of the information decrypts the cipher text back to its original plaintext form. Both parties to this transaction must have at their disposal one or more keys that allow them to encrypt and decrypt messages.

A very simple encryption method that has been in use for thousands of years is called a Caesar cipher. In all Romance languages, the character set for text (AKA alphabet) for text is ordered as a sequence of distinct values. This encryption strategy replaces each character in the original message with the character that occurs a given distance away in the sequence.
