The Enigma machine was invented by German engineer Arthur Scherbius at the end of World War I. [4] The German firm Scherbius & Ritter, co-founded by Scherbius, patented ideas for a cipher machine in 1918 and began marketing the finished product under the brand name Enigma in 1923, initially targeted at commercial markets.

Discovering the logical structure of the machine may be called "breaking" it, a one-off process except when changes or additions were made to the machines. Finding the internal and external settings for one or more messages may be called "solving" [ 13 ] – although breaking is often used for this process as well.
While the machine achieved a measure of popularity, its security was relatively weak; US cryptanalyst William Friedman reported that he solved the device within 2 hours and 41 minutes. In the history of cryptography , the Kryha machine was a device for encryption and decryption, appearing in the early 1920s and used until the 1950s.

Several complex machines were built by the British to aid the attack on Tunny. The first was the British Tunny. [27] [28] This machine was designed by Bletchley Park, based on the reverse engineering work done by Tiltman's team in the Testery, to emulate the Lorenz Cipher Machine. When the pin wheel settings were found by the Testery, the Tunny ...
An HC-9 on display at Bletchley Park.. The HC-9 was a mechanical cipher device manufactured by the Swedish company AB Transvertex. It was designed in the early 1950s for the Swedish Armed Forces and in use from 1963 to 1995 as Krypteringsapparat 301 (Kryapp 301).
The M-209 was designed by Swedish cryptographer Boris Hagelin in response to a request for such a portable cipher machine, and was an improvement of an earlier machine, the C-36. The M-209 is about the size of a lunchbox , in its final form measuring 3 + 1 ⁄ 4 by 5 + 1 ⁄ 2 by 7 inches (83 mm × 140 mm × 178 mm) and weighing 6 pounds (2.7 ...
