Kerberos is a network authentication protocol. It is designed to provide strong authentication
for client/server applications by using secret-key cryptography.The Kerberos protocol uses
strong cryptography so that a client can prove its identity to a server (and vice versa) across
an insecure network connection. After a client and server has used Kerberos to prove their identity,
they can also encrypt all of their communications to assure privacy and data integrity
as they go about their business.
