What was the unbreakable German code machine used during World War II called?

The Enigma machine was a sophisticated encryption device used by the German military during World War II. It employed a series of rotors and wires to create a complex cipher, making the messages it generated extremely difficult to decode without knowledge of the specific settings used at the time of encryption.

The design of the Enigma allowed for a vast number of possible configurations, providing a level of security that was considered unbreakable at the time. This machine played a crucial role in military communications, and its complexity contributed to the effectiveness of German operations. The code was eventually broken by Allied cryptanalysts, particularly by the efforts of mathematician Alan Turing and his team, which had a significant impact on the outcome of the war.

In contrast, the other terms mentioned do not accurately reflect the specific historical context. While "cipher" refers to the general concept of encoded messages, it does not point to a particular machine. "Secret Code Machine" and "Cryptic Device" are vague terms that do not have established historical significance in relation to World War II's encryption technologies. Thus, the Enigma is the definitive name associated with the German code machine of the era.
