Hi folks,

is there any chance to grasp why such a line - "No peer temporary key received" - is logged immediately after successful negotiation? It does not look harmful but I cannot understand *how ECDHE can do without the ephemeral key*.

The above is logged by Stunnel 5.67/5.68; whereas Stunnel 5.66 logs the very same moments differently: it says "SSL_get_peer_tmp_key: Peer suddenly disconnected" (but this can hardly be true).
