Vince is choosing a symmetric encryption algorithm for use in his organization. He would like to choose the strongest algorithm from the choices below. What algorithm should he choose? 

Kevin is configuring a web server to use digital certificates. What technology can he use to allow clients to quickly verify the status of that digital certificate without contacting a remote server?

Acme Widgets has 10 employees, and they all need the ability to communicate with one another using a symmetric encryption system. The system should allow any two employees to securely communicate without other employees eavesdropping. If an 11th employee is added to the organization, how many new keys must be added to the system?

referring to the scenario in question9, if Acme Widgets switched to an asymmetric encryption algorithm, how many keys would be required to add the 11th employee?
