NAME

       SSL_get_peer_cert_chain - get the X509 certificate chain of the peer


LIBRARY

       libcrypto, -lcrypto


SYNOPSIS

        #include <openssl/ssl.h>

        STACK_OF(X509) *SSL_get_peer_cert_chain(const SSL *ssl);


DESCRIPTION

       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.


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 STACK_OF(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 STACK_OF(X509)
           The return value points to the certificate chain presented by the
           peer.
