Test your knowledge with these top questions!
Question 1
The German Enigma cipher machine had a fatal design flaw that prevented a typed letter from doing what?
Because the Enigma machine used a reflector, a letter could never be encrypted as itself—a flaw that Allied codebreakers exploited to eliminate millions of possible settings.
Question 2
German operators weakened Enigma security by routinely ending messages with what predictable phrase?
Codebreakers relied on "cribs" (predictable known text), and the mandatory sign-off "Heil Hitler" gave them exactly what they needed to crack the daily codes.
Question 3
Computer pioneer Alan Turing built the electromechanical Bombe machine during World War II to do what?
Alan Turing's Bombe machine rapidly checked logical contradictions to determine the specific rotor positions the Germans had chosen for their Enigma machines that day.
Question 4
The Enigma machine achieved its complex encryption by using spinning rotors to do what?
Every time an operator pressed a key on the Enigma, one or more rotors would rotate, completely changing the electrical pathway for the very next letter.
