Caesar Cipher
The Caesar cipher is a code Julius Caesar invented when he mailed letters. He invented it so if his messenger was robbed of that letter and the robber wouldn't be able to read it. It is probably one of the most simple codes ever. It is 3 letters back so A would be X. The Rot Cipher is almost the same as the Caesar Cipher.
