The question
What did the German military use the Enigma machine for during World War II?
- Encoding secret messages(correct answer)
- Aiming long-range guns
- Detecting enemy aircraft
The answer: Encoding secret messages
The German military command used Enigma to encode strategic messages before and during World War II. Each key press sent an electrical signal through rotating wheels and a plugboard that scrambled the letters, and operators changed the settings according to daily orders. Polish mathematician Marian Rejewski first broke it in the early 1930s, and Alan Turing's team later read its messages.
