This repo is a sample of some basic encryption methods, and some references for further reading. It is the public half of an interactive unit on encryption being developed for an undergraduate ...

A Python-based implementation of Row and Column Transposition Ciphers for text encryption and decryption. Features an interactive CLI interface, support for custom keys, and automated padding handling ...

The message is called the plaintext because it is the unchanged source information. Example: The cat ran away. The secret message generated is called a cipher or ciphertext and it is the encrypted ...

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 ...
