===Various machines===

During [[World War II]] (WWII), both the Germans and Allies developed additional rotor machines. The Germans used the [[Lorenz SZ 40/42]] and [[Siemens and Halske T52]] machines to encipher teleprinter traffic which used the [[Baudot code]]; this traffic was known as [[Fish (cryptography)|Fish]] to the Allies. The Allies developed the [[Typex]] (British) and the [[SIGABA]] (American). During the War the [[Switzerland|Swiss]] began development on an Enigma improvement which became the [[NEMA machine]] which was put into service after World War II. There was even a Japanese developed variant of the Enigma in which the rotors sat horizontally; it was apparently never put into service. The Japanese [[PURPLE]] machine was not a rotor machine, being built around electrical [[stepping switch]]es, but was conceptually similar.

Rotor machines continued to be used even in the computer age. The [[KL-7]] (ADONIS), an encryption machine with 8 rotors, was widely used by the U.S. and its allies from the 1950s until the 1980s. The last [[Canada|Canadian]] message encrypted with a KL-7 was sent on June 30, 1983. The Soviet Union and its allies used a 10-rotor machine called [[Fialka]] well into the 1970s.

A unique rotor machine called the Cryptograph was constructed in 2002 by [[Netherlands]]-based Tatjana van Vark. This unusual device is inspired by Enigma, but makes use of 40-point rotors, allowing letters, numbers and some punctuation; each rotor contains 509 parts.

A software implementation of a rotor machine was used in the [[crypt (Unix)|crypt]] command that was part of early [[Unix|UNIX]] operating systems. It was among the first software programs to run afoul of [[Export of cryptography#Cold War era|U.S. export regulations]] which classified [[cryptographic]] implementations as munitions.
