WebRotor Machines In cryptography, a rotor machine is an electro-mechanical stream cipher device used for encrypting and decrypting messages. In the 1920s, various mechanical encryption devices were invented to automate the process of encryption. Most were based on the concept of a rotor, a mechanical wheel wired to perform a general substitution ... WebCipher machines and cryptographic methods The 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.
