At 4:30: A mistake: step 3: When the file server gets the token, it "decrypts" (not "encrypts") the token with the secret key shared with TGS.
In Greek mythology, Kerberos is a dog with three heads. But today I will not talk about the dog. Kerberos is an authentication protocol for client/server applications. I will demonstrate with an example how Kerberos works. Keep in mind, Kerberos implements private key encryption.

Great video! However, there were 2 mistakes: 1) At 2:26, the request is encrypted with a HASH of the clients password, not the clients actual password (because that would mean that the Authentication Server is storing the clients password in plaintext, which is NOT GOOD - it instead stores a hash of the clients password) 2) At 4:32, it should be "decrypts the token" instead of "encrypts the token", because it's already been encrypted. Other than that, great explanation. Very easy to understand!

@@sulekha3771 because you cant just store passwords as plaintext anywhere at any time. If someone somehow gained access to the auth server, they could just see the passwords and bypass the other steps.

@sb_4 2 жыл бұрын

I think you're right in your first point about this being wrong, but I don't think you're correct either. The initial request to the AS is completely plaintext. Please do correct me if you think I'm wrong. I agree that the _response_ (including the TGS session key etc) from the AS would be encrypted using the hash of the client's password.
