|
||
|
|
|
||
|
|
=head1 SYNOPSIS
|
||
|
|
|
||
|
|
#include <openssl/ssl.h>
|
||
|
|
|
||
|
|
X509 *SSL_get_peer_certificate(SSL *ssl);
|
||
|
|
|
||
|
|
=head1 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.
|
||
|
|
|
||
|
|
=head1 NOTES
|
||
|
|
|
||
|
|
That a certificate is returned does not indicate information about the
|
||
|
|
verification state, use L<SSL_get_verify_result(3)|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().
|
||
|
|
|
||
|
|
