In cryptography, a rotor machine is an electro-mechanical stream cipher device used for encrypting and decrypting messages. Rotor machines were the cryptographic state-of-the-art for much of the 20th century; they were in widespread use from the 1920s to the 1970s.

This article contains technical details about the rotors of the Enigma machine. Understanding the way the machine encrypts requires taking into account the current position of each rotor, the ring setting and its internal wiring.

The Hebern Rotor Machine was an electro-mechanical encryption machine built by combining the mechanical parts of a standard typewriter with the electrical parts of an electric typewriter, connecting the two through a scrambler.

What is the Rotor? Definition: It is the moving part in an electromagnetic system of the motor, generator and an alternator. It is also called as the Flywheel, rotating magnetic core, an alternator. In an alternator, it includes permanent magnets that move approximately to the iron plates of the stator to produce an AC (Alternating Current).

Aug 31, 2021 · The HX-63 cipher machine is an electromechanical, rotor-based system designed and built by Crypto AG. The machine uses nine rotors [center right] to encrypt messages. A dual paper-tape printer is at the upper left. Growing up in New York City, I always wanted to be a spy.

A generalized rotor machine (GRM, as conceived by Scherbius) is an electromechanical device that has a keyboard, a series of rotors, and a set of lamps that are used as display devices.

Rotors is a typical American expression. In UK-English, rotors are commonly known as wheels. Traditionally, the smaller mechanical cipher machines from Hagelin (Crypto AG) do not belong …

Cryptographic rotor machines were mechanical devices that allowed to use encryption algorithms that were much more complex than manual ciphers.

Learn about the rotor machine and study its components. Explore the uses of cipher machines, history of the rotor machine, and examples of cipher equipment.

Aug 8, 2017 · The Hebern Rotor Machine was a major innovative leap in cipher technology and was also the first time electrical circuitry was used in a cipher device. Despite its failure to gain market acceptance, it had far-reaching historical significance in World War II and beyond.
