=head1 DESCRIPTION
|
|
|
|
|
|
|
|
|
|
SSL_get_peer_cert_chain() returns a pointer to STACKOF(X509) certificates
|
|
|
|
|
forming the certificate chain of the peer. If called on the client side,
|
|
|
|
|
the stack also contains the peer's certificate; if called on the server
|
2001-02-16 02:09:53 +00:00
|
|
|
side, the peer's certificate must be obtained separately using
|
2000-09-20 16:55:26 +00:00
|
|
|
L<SSL_get_peer_certificate(3)|SSL_get_peer_certificate(3)>.
|
|
|
|
|
If the peer did not present a certificate, NULL is returned.
|
|
|
|
|
|
|
|
|
|
=head1 NOTES
|
|
|
|
|
|
|
|
|
|
The peer certificate chain is not necessarily available after reusing
|
|
|
|
|
a session, in which case a NULL pointer is returned.
|
|
|
|
|
|
|
|
|
|
The reference count of the STACKOF(X509) object is not incremented.
|
|
|
|
|
If the corresponding session is freed, the pointer must not be used
|
|
|
|
|
any longer.
|
|
|

|
|
|
|
|
|
|

|
|
No certificate was presented by the peer or no connection was established
|
|
|
|
|
or the certificate chain is no longer available when a session is reused.

|
|
|
|
|
|
=item Pointer to a STACKOF(X509)
|
|
|
|
