Enigma machine

The Enigma machine was a complex device used by the Germans during World War II to encrypt messages, ensuring that their communications remained secret. It resembled a typewriter and used a series of rotating wheels, or rotors, to scramble letters. Each rotor had a different wiring pattern, creating a vast number of possible settings and making it extremely difficult to decode messages without knowing the exact configuration. The Enigma's encryption was considered nearly unbreakable until Allied cryptanalysts, particularly in Poland and later at Bletchley Park in Britain, successfully deciphered it, aiding in the war effort.
