The Enigma machines produced a polyalphabetic substitution cipher.During World War I, inventors in several countries realised that a purely random key sequence, containing no repetitive pattern, would, in principle, make a polyalphabetic substitution cipher unbreakable. [6]
With their help," writes Rejewski, "we continued solving Enigma daily keys." [3] The sheets were used by the Poles to make the first wartime decryption of an Enigma message, on 17 January 1940. [7] [9] In May 1940, the Germans once again completely changed the procedure for enciphering message keys (with the exception of a Norwegian network).
The German Enigma used a combination key to control the operation of the machine: rotor order, which rotors to install, which ring setting for each rotor, which initial setting for each rotor, and the settings of the stecker plugboard. The rotor settings were trigrams (for example, "NJR") to indicate the way the operator was to set the machine.
Enigma machine G was modified to the Enigma I by June 1930. [55] Enigma I is also known as the Wehrmacht, or "Services" Enigma, and was used extensively by German military services and other government organisations (such as the railways [56]) before and during World War II.

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.
