Web1 Caesar Cipher The Caesar cipher shifts all the letters in a piece of text by a certain number of places. The key for this cipher is a letter which represents the number of place for the shift. So, for example, a key D means \shift 3 places" and a key M means \shift 12 places". Note that a key A means \do not shift" and
