British Cryptologists Broke Enigma Key

Enigma machine is an encryption device developed and initially used in commercial market. Early models were used commercially from the early 1920s, and later adopted by military and government services of several countries, most notably Nazi Germany before and during World War II. Enigma has an electromechanical rotor mechanism that scrambles the 26 letters of the alphabet. The rotor mechanism changes the electrical connections between the keys and the lights with each keypress. The security of the system depends on a set of machine settings that were generally changed daily during the war, based on secret key lists distributed in advance.

On July 9, 1941, crackerjack British cryptologists broke the secret code used by the German army, which they use to direct ground to air operations on the Eastern front. British and Polish experts had already broken many of the Enigma codes before for the Western front.
