@deftypefun {const gnutls_datum_t *} {gnutls_certificate_get_peers} (gnutls_session_t          @var{session}, unsigned int * @var{list_size})

@var{session}: is a gnutls session

@var{list_size}: is the length of the certificate list (may be @code{NULL} )

Get the peer's raw certificate (chain) as sent by the peer.  These

certificates are in raw format (DER encoded for X.509).  In case of

a X.509 then a certificate list may be present.  The list

is provided as sent by the server; the server must send as first

certificate in the list its own certificate, following the

issuer's certificate, then the issuer's issuer etc. However, there

are servers which violate this principle and thus on certain

occasions this may be an unsorted list.

In resumed sessions, this function will return the peer's certificate

list as used in the first/original session.

@strong{Returns:} a pointer to a @code{gnutls_datum_t}  containing the peer's

certificates, or @code{NULL}  in case of an error or if no certificate

was used.
