Unlocking the Secrets of the British Typex Cipher Machine 🕵️‍♂️

#cryptology, #cryptography, #cryptanalysis

In this video, you learn how the British rotor encryption machine Typex works. We first discuss the components of the machine, its keyspace size and its unicity distance. Then, we use CrypTool 2 to encrypt and decrypt using the Typex component. Finally, we have a look at the "Virtual Typex", a really nice Typex simulator in the browser.

You can find the "Virtual Typex" here: https://typex.virtualcolossus.co.uk/

Also, I wrote a blogpost about the Typex, which you can read here: https://www.kopaldev.de/2023/03/20/the-british-typex-cipher-machine-explained/

If you are interested in learning the fundaments of cryptology, let me invite you to have a look at our video series about the basics of cryptology, also for beginners: https://youtu.be/jbumW7Ym03o
