SSL_get_peer_cert_chain - get the X509 certificate chain
of the peer
SYNOPSIS
#include <openssl/ssl.h>
STACKOF(X509) *SSL_get_peer_cert_chain(SSL *ssl);
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
side, the peer's certificate must be obtained separately
using SSL_get_peer_certificate(3). If the peer did not
present a certificate, NULL is returned.
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.
RETURN VALUES
The following return values can occur:
NULL
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.
Pointer to a STACKOF(X509)
The return value points to the certificate chain
presented by the peer.
