Caesar Ciphers

All NEW! Named after Julius Caesar, who apparently wrote many of his letters in code, this cipher substitutes one letter of the alphabet with another according to a rule, or "key". For example, if the key was "Right 3", if you wanted to write an E you would hop along the alphabet 3 steps to the right, and use H instead.
