SSL_GET_PEER_CERT_CHAIN(3) OpenSSL SSL_GET_PEER_CERT_CHAIN(3)
SSL_get_peer_cert_chain - get the X509 certificate chain of
the peer
#include <openssl/ssl.h>
STACKOF(X509) *SSL_get_peer_cert_chain(const SSL *ssl);
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.
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.
The following return values can occur:
NULL
No certificate was presented by the peer or no connec-
tion 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.
