The Enigma machine is a cipher device developed and used in the early- to mid-20th century to protect commercial, diplomatic, and military communication. It was employed extensively by Nazi Germany during World War II , in all branches of the German military .
The Enigma machines were a family of portable cipher machines with rotor scramblers. [1] Good operating procedures, properly enforced, would have made the plugboard Enigma machine unbreakable to the Allies at that time. [2] [3] [4] The German plugboard-equipped Enigma became the principal crypto-system of the German Reich and later of other ...
Hans-Thilo Schmidt (13 May 1888 – 19 September 1943) codenamed Asché or Source D, was a German spy who sold secrets about the Enigma machine to the French during World War II. The materials he provided facilitated Polish mathematician Marian Rejewski 's reconstruction of the wiring in the Enigma's rotors and reflector ; thereafter the Poles ...
The machine was developed by British mathematician Alan Turing, and it was used to decode messages sent by the Nazi military. Bought for $115, a WWII Enigma machine sells for $51,000 Skip to main ...
The Enigma machine was an electromechanical device, equipped with a 26-letter keyboard and 26 lamps, corresponding to the letters of the alphabet. Inside was a set of wired drums (rotors and a reflector) that scrambled the input. The machine used a plugboard to swap pairs of letters, and the encipherment varied from one key press to the next.

The Enigma-M4 key machine Key manual of the Kriegsmarine "Der Schlüssel M".. The Enigma-M4 (also called Schlüssel M, more precisely Schlüssel M Form M4) is a rotor key machine that was used for encrypted communication by the German Kriegsmarine during World War II from October 1941.
Military Enigma machine, model "Enigma I", used during the late 1930s and during the war; displayed at Museo scienza e tecnologia Milano, Italy. German Army cryptographic systems of World War II were based on the use of three types of cryptographic machines that were used to encrypt communications between units at the division level.
The bombe (UK: / b ɒ m b /) was an electro-mechanical device used by British cryptologists to help decipher German Enigma-machine-encrypted secret messages during World War II. [1] The US Navy [ 2 ] and US Army [ 3 ] later produced their own machines to the same functional specification, albeit engineered differently both from each other and ...
