       SSL_get_peer_certificate - get the X509 certificate of the peer

	#include <openssl/ssl.h>

	X509 *SSL_get_peer_certificate(SSL *ssl);

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

       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_ver‐
       ify(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 verifica‐
       tion 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 certifi‐
       cate is freed. The X509 object must be explicitly freed using

       The following return values can occur:

	   No certificate was presented by the peer or no connection was

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