 Julius Caesar protected his confidential information by encrypting it using a cipher. Caesar's cipher (check ***Resources*** tab for more info) shifts each letter by a number of letters. If the shift takes you past the end of the alphabet, just rotate back to the front of the alphabet. In the case of a rotation by *3, w, x, y* and *z* would map to *z, a, b* and *c*.
