SSL_get_peer_certificate(3)			   SSL_get_peer_certificate(3)

NAME
       SSL_get_peer_certificate - Get the X509 certificate of the peer

SYNOPSIS
	#include <openssl/ssl.h>

       X509 *SSL_get_peer_certificate(
	       SSL *ssl );

DESCRIPTION
       The  SSL_get_peer_certificate()	function returns a pointer to the X509
       certificate the peer presented. If the peer did not present a  certifi‐
       cate, NULL is returned.

NOTES
       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()).	If an anonymous cipher is used, no certificates are sent.

       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
       X509_free() function.

RETURN VALUES
       The  following return values can occur: No certificate was presented by
       the peer or no connection was established.  The return value points  to
       the certificate presented by the peer.
