As the new intern for the summer, you have been asked to investigate two methods of e-mail encryption: S/MIME and Pretty Good Privacy (PGP). Compare and contrast the two systems.
1. Why do two standards exist?
2. Which do you think your employer should standardize on? Why?
Optional activity: Set up S/MIME or PGP-based plug-ins in student e-mail clients. Use the activity to learn how to get/create a public/private key pair and encrypt mail.
