exchange_keys Method

Causes the class to exchange a new set of session keys with the SSHHost .

Syntax

def exchange_keys() -> None: ...

Remarks

SSH key renegotiation can be initiated by either end of an established SSH connection. exchange_keys allows the user to start such a renegotiation with the ssh_host. During this process, on_ssh_status events will fire containing updates regarding the key negotiation process.

The SSH 2.0 specification recommends that key renegotiation be done once for 2 gigabytes (GB) of data processed by the connection, or once every day. This makes it more difficult to break the security of data-intensive or long-lived connections.
