What is the Enigma Machine?
The Enigma machine is a specialized typewriter used for writing and decrypting encrypted messages. It was most widely used during World War II by the German military for secure communication. Thanks to this machine, enemies could not easily determine the content of the messages.

How Does Enigma Work?
The Enigma resembles a typewriter from the outside but contains rotating wheels called rotors. When a user presses a letter, the machine transforms it into a different letter. For example, pressing the letter “A” might produce “T” on the display. This transformation changes with each keystroke, making it extremely difficult to decipher the message.
Since the machine uses different settings each day, simply possessing the machine is not enough to understand Enigma messages; the specific daily settings must also be known. This made it very difficult for enemies to decrypt the messages.
Why Is It Important?
The Enigma machine remained a great secret during the war. However, British mathematician Alan Turing and his team successfully broke the Enigma code. This achievement helped shorten the war and saved millions of lives. The decryption of Enigma also contributed significantly to the development of computer science.

Enigma Today
Today, Enigma machines are displayed in museums. For example, the Enigma Museum and the International Museum of World War II explain the history and operation of these machines. Additionally, some websites offer simplified models of Enigma to teach how encryption works.
