SSL_get_peer_cert_chain - get the X509 certificate chain of the peer
STACK_OF(X509) *SSL_get_peer_cert_chain(const SSL *ssl);
SSL_get_peer_cert_chain() returns a pointer to STACK_OF(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 STACK_OF(X509) object is not incremented.
If the corresponding session is freed, the pointer must not be used any
The following return values can occur:
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 STACK_OF(X509)
The return value points to the certificate chain presented by the
