WebThe German Enigma cipher machine is arguably the world's most well-known cipher machine, mainly because of the vital role it played during WWII . There are however many other interesting cipher machines, such as the mechanical series from Boris Hagelin and the Russian M-125 Fialka . Webciphers.) In summary, affine encryption on the English alphabet using encryption key (α,β) is accomplished via the formula y ≡ αx + β (mod 26). (Now we can see why a shift cipher is just a special case of an affine cipher: A shift cipher with encryption key ‘ is the same as an affine cipher with encryption key (1,‘).)
