9 #include <openssl/ssl.h>
10
11 STACK_OF(X509) *SSL_get_peer_cert_chain(const SSL *ssl);
12
13=head1 DESCRIPTION
14
15SSL_get_peer_cert_chain() returns a pointer to STACK_OF(X509) certificates
16forming the certificate chain of the peer. If called on the client side,
17the stack also contains the peer's certificate; if called on the server
18side, the peer's certificate must be obtained separately using
19L<SSL_get_peer_certificate(3)|SSL_get_peer_certificate(3)>.
20If the peer did not present a certificate, NULL is returned.
21
22=head1 NOTES
23
24The peer certificate chain is not necessarily available after reusing
25a session, in which case a NULL pointer is returned.
26
27The reference count of the STACK_OF(X509) object is not incremented.
28If the corresponding session is freed, the pointer must not be used
29any longer.

31=head1 RETURN VALUES
32
33The following return values can occur:
34
35=over 4
36
37=item NULL
38
39No certificate was presented by the peer or no connection was established
40or the certificate chain is no longer available when a session is reused.
41
42=item Pointer to a STACK_OF(X509)
