Find client certificate information from server in OpenSSL

问题

I'm programming an application that uses a SSL connection to ensure only valid clients connect (using client certificates). Is there some API call the server can call on a connection to retrieve information about the certificate the client used?

回答1:

Try SSL_get_peer_certificate method.
