Caesar Quote by Tom Pollock
““A Caesar shift is about the simplest code in the world – perfect for the Roman emperor who’s long on secrets but short on time. To make one, you just write out the alphabet, A to Z, then pick a secret phrase… and write it out underneath the first few letters of your alphabet, dropping any repeated letters…””
