Vigenere Cipher
The Vigenere Cipher is a 26x26 grid of letters a-z. It is a more complicated cipher so I will have to try to demonstrate with explaining battle ship.
Directions
1. Choose a code word (any word. no numbers)
2. Write it like this (my code word will be "code") i m t r y i n g t o e x p l a i n h o w t o d o t h i s it doesn't matter if the code word cant fit evenly c o d e c o d e c o d e c o d e c o d e c o d e c o d e
3. Look at the grid and follow the row i and the column c to the intersection like in battle ship. the letter they intersect on is k. that is how you encode it. To decode it take the code letter in this case c and go until you find k. Then go up all the way so you will find i.
