If you use a shift X, the equivalent shift, from 0 to 25, can be calculated as: X mod 26 or equivalently the remainder when you divide X by 26 Hope this makes sense. A Caesar cipher is very easy to design, but also very easy to decode. Vote for difficulty :. Columnar Double Myszkowski Rail fence Route. Caesar used ciphers so that important information, such as the location of a attack or the date it would be carried out, would be unknown to enemies but know to the rest of his troop.
