I am trying to understand what\'s the actual difference between SSL and Kerberos authentications, and why sometimes I have both SSL traffic and Kerberos. Or does Kerberos use S
A short answer: SSL and Kerberos both use encryption but SSL uses a key that is unchanged during a session while Kerberos uses several keys for encrypting the communication between a client and a client.
In SSL, encryption is dealt with directly by the two ends of communication while in Kerberos, the encryption key is provided by a third party - some kind of intermediate - between the client and the server.
