In this project, you are tasked to implement a Python class (call it TranspositionCipher) that can encrypt and decrypt a message using the transposition cipher—a simple yet effective way of encrypting ...

Type: Substitution cipher. How it Works: Typically, the Caesar Cipher shifts the alphabet by a certain number of positions. When using a word as a key, the letters of the key determine how much each ...

It’s been a couple of Math Mondays since we last looked at columnar transposition ciphers, so let’s jump back in. In the It’s been a couple of Math Mondays since we last looked at columnar ...

This was one of the most secure hand ciphers used in the Second World War. It was used by both the Allies and the Axis, and served both well. Its main weakness was that if the attacker intercepted two ...
