  2. How will you organize the keys, can you use the published PGP keys at all? If so, do so. If not - how will you exchange your public keys in the group?
  3. Write a final message for each person in this course and publish it in the Secret Messages forum, encoded with their public keys.
  4. Decode their messages to you with your secret key.

You have two weeks to do this exercise, it is worth 10 points. If you need to be done early, let us know, so we can encode messages for you to decode.
