The fifth lesson in a sequence of lessons that challenge students to think about different ways that plain text can be converted, encrypted or coded into cipher text.

This lesson introduces the Playfair cipher. This is a more challenging lesson to think about than the previous lessons and may need to be significantly differentiated for younger or students with additional educational needs.
