Vigenere Cipher

The Vigenere Cipher is a more complex substitution cipher that uses multiple Caesar Ciphers to encode a message. The Cipher is given a key, and the letters of the key are used to determine the Caesar shift used for each letter of the message, with the first letter of the key applying to the first letter of the message and so on.

The Vigenere Cipher can be visualized as a 26 by 26 grid, with each row and column showing the Caesar-shifted alphabet corresponding to its first letter. The cipher character is located where the key letter's column and message letter's row intersect.
