Your co-worker is not familiar with technical concepts. He asks you to explain Secure Shell (SSH)
and the way it works. Which of the following is an appropriate and accurate explanation you can
give to this non-technical person?

A.
SSH uses RSA and public keys to authenticate and encrypt before you can defragment the
hard drive.

B.
SSH uses DSA and RSA to protect authentication information, and asymmetric-key encryption
to provide data confidentiality.

C.
SSH allows you to gain secure access to a remote computer and then execute commands to
control the system.

D.
SSH uses a Telnet-like interface, public keys or standard authentication methods, and then
symmetric keys.
