During World War II, the Enigma machine was used by the German military to encrypt highly sensitive tactical communications.

This sophisticated device utilized a series of rotating wheels to scramble messages into a complex cipher that changed with every keystroke.

Because the encryption settings were altered daily, Allied forces initially found the code impossible to break through traditional methods.

However, a team of mathematicians led by Alan Turing developed the 'Bombe,' an early electromechanical computer designed to crack the Enigma settings.

The successful decryption of these messages is estimated to have shortened the war by at least two years and saved millions of lives.
