Key Exchange

When a client requests a new session, the server and client use a key exchange protocol to decide on a one-time session key. Key exchange protocols enable the server and client to establish a shared secret key, even though the communications take place in the open. After the key is established, the client and server encrypt subsequent communications using the session key and an agreed upon cipher.

Use the Key Exchange pane to control which key exchange protocols the server supports. You can also configure the server to require a new key exchange after a specified time interval has elapsed.
