Vigenère Cipher. In the Vigenère Cipher, we use a special keyword to encrypt a message. We represent each letter of the alphabet as a number from 0-25. In order, we add each letter from the keyword to the message and mod by 26. If the keyword is shorter than the message, we simply repeat the keyword. For example, lets say that the message is HOWSTUFFWORKS and the keyword is CIPHER. The following table shows how we can find the final...
