The document discusses the Enigma machine, which was created by Nazi Germany during World War II to encrypt secret messages. The Enigma machine used a series of rotors and settings that scrambled letters in complex ways, making the encrypted messages nearly impossible to decipher without the proper settings. However, Allied codebreakers were eventually able to build machines like the Bomba that could decipher the Enigma messages in a couple hours, helping the Allies gain an advantage in the war.

3. The Enigma Machine
Created by the Nazi Germany to pass
encrypted message for their secret
messages so that when the Americans
intercepted their messages it was a
bunch of letters with no meaning.

4. Structurally Enigma
• Enigma Facts:
• 3 rotors (slow, medium and fast).
• 5 Settings Set.
• Each rotor having 26 independent
settings.

5. Example: First time pressing ‘A’ will print out ‘B’ but the second time you press ‘A’
it will print ‘F’.
Probabilities: 158,962,555,217,826,360,000-to-1 (159 Quintillion to 1)

making me wanna
throw up!

7. Decipher: The Bomba
The Bomba machine could decipher the Enigma in a couple of hours.
