     SSL_get_peer_certificate() returns a pointer to the X509
     certificate the peer presented. If the peer did not present
     a certificate, NULL is returned.

     Due to the protocol definition, a TLS/SSL server will always
     send a certificate, if present. A client will only send a
     certificate when explicitly requested to do so by the server
     (see SSL_CTX_set_verify(3)). If an anonymous cipher is used,
     no certificates are sent.

     That a certificate is returned does not indicate information
     about the verification state, use SSL_get_verify_result(3)
     to check the verification state.

     The reference count of the X509 object is incremented by
     one, so that it will not be destroyed when the session
     containing the peer certificate is freed. The X509 object
     must be explicitly freed using X509_free().

     The following return values can occur:

     NULL
         No certificate was presented by the peer or no
         connection was established.

     Pointer to an X509 certificate
         The return value points to the certificate presented by
         the peer.
