SSL_get_peer_cert_chain(3)SSL_get_peer_cert_chain(3)NAMESSL_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
The SSL_get_peer_cert_chain() function 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 cer‐
tificate; if called on the server side, the peer's certificate must be
obtained separately using the SSL_get_peer_certificate() function. 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.
RETURN VALUES
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. The return value points
to the certificate chain presented by the peer.
