=head1 NAME
|
|
|
|
SSL_get_peer_certificate - get the X509 certificate of the peer
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
#include <openssl/ssl.h>
|
|
|
|
X509 *SSL_get_peer_certificate(const 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
|
|
|
|
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.
