Maybe you’ve dreamed of designing a cipher that is unbreakable. Or working against time to break a secret code. Or trying to create the perfect invisible ink. If this sounds like you, then this program is just for you.
Doesn’t that sound tempting? That is what Paul B. Janeczko says in his great book Top Secret. We’re going to learn from him, using his book! Learn all about different kinds of secret codes and how to make your own! Why do you have to have your own secret code? Do you really WANT your little sister knowing your stuff?
