WebImagine Alice and Bob decided to communicate using the Caesar Cipher First, they would need to agree in advance on a shift to use-- say, three. So to encrypt her message, Alice would need to apply a shift of three to each letter in her original message. So A becomes D, B becomes E, C becomes F, and so on. http://practicalcryptography.com/ciphers/caesar-cipher/

http://www.cs.trincoll.edu/~crypto/historical/caesar.html 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
