Can you understand this? What is it? Gibberish. Some kind of a cryptic code, message…? What does it mean? How can it hide a message …? How do we break it? Wait, who used this, again? … and why?

On 2022-01-22 (Saturday), we meet at 16:00 to learn about the Enigma machine, a 20-century electro-mechanical encryption device heavily used during the World War II by the German military to transmit secret messages and encrypt their communication.

We’ll learn how the Enigma worked, was used and later broken by foreign intelligence services. We’ll mention spy games, military campaigns, encrypted traffic and even encrypt and decrypt our own messages! No preexisting knowledge required. Everyone’s invited. Entry is free. 🙂
