Introduction To Cryptography – The Vigenère Cipher : Racking The Code And Exploring Its Challenges

In my first cryptography blogpost I introduced some definitions and concepts, one of them was the concept of substitution ciphers. In short, those ciphers substitute plaintext tokens by some methodology that depends on the cipher’s key. I did forget to mention – encryption and decryption methodologies might be slightly different but the key would be used for both encryption …
