Answer 1

Matrix Encryption

Perhaps when you were a child, you had a decoder ring from a cereal box or Cracker Jacks. If you wanted to send someone a secret message, you could use the ring to encode your message and send the encrypted message to your friend. Your friend uses the same ring to decode the message. (In the movie "A Christmas Story", the hero sends in Ovaltine labels to get a decoder ring so he can decode the secret messages from Orphan Annie which were broadcast on the radio show.)
