Hi, I have two Windows based stations with one hosting a specific service. Stunnel is used to create a secure connection. As stated on the auth page, I have implemented PSK to prevent MITM Attack but also as a way to authenticate connections and limit who can connect to the server. I would like to add an extra layer of security by having the Server only accept connections when the client submits a pre-agreed self cert. verifyPeer does not seem to work with self certificate. I would like to end up with PSK + certificate check. Is there a way to achieve that with self certificate on Stunnel? Thanks.
