NAME

       SSL_get_peer_cert_chain - get the X509 certificate chain
       of the peer


LIBRARY

       libcrypto, -lcrypto


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 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 pre-
           sented by the peer.
