Book Cipher

The book cipher can take a long time to crack, but it is really simple. To encode your message, take a book, or a long piece of writing, that you know the receiver of the message has, and find the words you need for your message. A small example of a message in this text would be 31 45 18 13 15 16 10.
If you did it right, you would have ended up with "Your message is really simple to crack."
