The Enigma Machine is one of the most iconic encryption machine. It's famous from books and movies and it was the nemesis that Alan Turing and his international team defeated at Bletchley Park.
Trying a working original hands-on is almost impossible nowadays - they are sold at auctions for the price of a large family home. That's why several apps exist - and electronic replicas. One of them is Enigma Touch by Jürgen Müller. It is very close to the originals.
In the workshop, I'll explain how Enigma was used (as briefly as possible, no maths!), then we'll take a demo device and play around with it. I'm going to bring some historical messages that you can decrypt - or you come up with your own messages.
If you bring an Enigma app on your smart device or web browser, you can participate and exchange messages with the physical device - they are of course compatible to each other if implemented correctly.
My goal is to learn about didactics: How fast can my audience grasp the UI of Enigma Touch, how much do I need to explain to you, what are your FAQs? And you? Maybe you just want to try out the gadget.
