Caesar Cipher

The Caesar Cipher is a simple substitution cipher that replaces each letter in a message with a letter a set number of steps left or right in the alphabet. If you reach the end of the alphabet, you wrap around to the start, and vice versa if you reach the start; for example, if you shift left by 3, A becomes X, B becomes Y, and C becomes Z. To decode a Caesar Cipher, you simply shift the same number of steps in the opposite direction.
