If the peer did not present a certificate, NULL is returned. + +=head1 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 +L<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 L<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(). + +=head1 RETURN VALUES + +The following return values can occur: + +=over 4 + +=item NULL + +No certificate was presented by the peer or no connection was established. + +=item Pointer to an X509 certificate + +The return value points to the certificate presented by the peer. + +=back + +=head1 SEE ALSO + +L<ssl(3)>, L<SSL_get_verify_result(3)>, +L<SSL_CTX_set_verify(3)> + +=head1 COPYRIGHT + +Copyright 2000-2016 The OpenSSL Project Authors.
