Polybius Square Encryption in Python

Beginner

In this project, you will learn how to implement the Polybius square encryption algorithm. The Polybius square is a 5x5 grid that maps each letter of the English alphabet to a pair of coordinates. By encrypting text using this method, you can create a coded message that can only be decrypted by someone with knowledge of the Polybius square.
