Master the Affine Cipher: A Simple Guide to Mathematical Substitution 🔐

#cryptology, #cryptography, #cryptanalysis

In this video, you learn how the affine cipher works. First, we introduce additive and multiplicative ciphers. Then we have a look at the affine cipher, its keyspace size and unicity distance. Finally, we build our own affine cipher workspace in CrypTool 2.

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
