The Enigma machine was used commercially from the early 1920s and was adopted by the militaries and governments of various countries—most famously, Nazi Germany. Cryptanalysis of the Enigma ciphering system enabled the western Allies in World War II to read substantial amounts of Morse-coded radio communications of the Axis powers that had ...
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.

Marian Adam Rejewski (Polish: [ˈmarjan rɛˈjɛfskʲi] ⓘ; 16 August 1905 – 13 February 1980) was a Polish mathematician and cryptologist who in late 1932 reconstructed the sight-unseen German military Enigma cipher machine, aided by limited documents obtained by French military intelligence.
He concentrated on cryptanalysis of the Enigma cipher machine used by Nazi Germany, together with Dilly Knox, a senior GC&CS codebreaker. [74] Soon after the July 1939 meeting near Warsaw at which the Polish Cipher Bureau gave the British and French details of the wiring of Enigma machine's rotors and their method of decrypting Enigma machine ...
The overall plot arc in which the British cryptographers were stymied for the first few years of the war and then a sudden breakthrough enabled them to finally break Enigma. In reality, the Polish cryptanalysts Marian Rejewski, Jerzy Różycki and Henryk Zygalski from the Polish Cipher Bureau had been breaking German Enigma messages since 1932 ...
An Enigma machine of four rotors was introduced in 1942 which stymied Hut 8's decryption efforts and led to German U-boats successfully attacking Allied shipping convoys again. Clarke had access to intercepted code papers and worked out that that same cipher was used on the fourth rotor as the three-rotor system, which enabled Shaun Wylie to ...
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 ...
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 ...
