Simply put, we 'shift' the letter A some number of spaces to the right, and start the alphabet from there, wrapping around when we get to Z. The way in which the shifted alphabet lines up ... WebRot-N/Rot cipher (for Rotation) is a simple character substitution based on a shift/rotation of N letters in an alphabet. E.g. one letter is replaced by another (always the same) that is located further (exactly N letters further) in the alphabet. This is the basis of the famous Caesar code and its many variants modifying the shift. fangelsismálastofnun

The Atbash cipher uses a = −1 . Considering the specific case of encrypting messages in English (i.e. m = 26 ), there are a total of 286 non-trivial affine ciphers, not counting the 26 trivial Caesar ciphers. hm catalunya
