That way I can identify device x from device y while looking at the traffic. Inside the flow object there is a client connection which contains `clientcert` variable. But this variable is None. \r\n\r\nflow.client_conn.clientcert --- gives none?\r\n\r\nAny ideas on why? Am I missing a concept here?\r\n"}}
