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
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.

NOTES
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().

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.
