Hello, i make a few changes and then the verifyon class was triggered and it worked just find. But i tried from another computer that do not has a client certificate installed, i run the IE and the window to select a client certificate was displayed, i clicked the ok button and the socket did not validate the certificate and return an answer. Then i activated the TLS option on the IE and then works fine. I need to be able to denied access to the socket if the client try to stablish a connection with the socket using only ssl or if this do not send a client certificate.

Best regards

Do you mean that you specified a CertVerifyEventHandler delegate and that it did not get called even though you used Mutual Authentication? Or do you mean that the server closed the connection after selecting a client certificate in the browser?
Sends data without calling the verify delegate shouldn't happen, of course.
If this is what you meant, can you send me a small but full example project that explains the bug you're seeing? I'm unable to reproduce that behavior on my computer [the verify delegate always gets called - as expected].
Oh, and by the way: what version of the library are you using? Are you using the latest version [v1.0.13.692]?

Hello, when i use the Internet Explorer as a client, and the TLS1 option is off, i receive a request of the client certificate as expected, but if i do not have installed a client certificate and press OK, then i receive the response from the socket anyway

Everything is working perfectly on my computer. If I connect to a small webserver with mutual authentication enabled, the CertVerifyEventHandler was always called as expected.

Can you post the code you're using? Perhaps you're using a wrong Credential Verification flag...
