       gnutls_certificate_set_x509_key_file - API function

SYNOPSIS         top

       #include <gnutls/gnutls.h>

       res, const char * certfile, const char * keyfile,
       gnutls_x509_crt_fmt_t type);

ARGUMENTS         top

       gnutls_certificate_credentials_t res
                   is a gnutls_certificate_credentials_t type.

       const char * certfile
                   is a file that containing the certificate list (path) for
                   the specified private key, in PKCS7 format, or a list of

       const char * keyfile
                   is a file that contains the private key

       gnutls_x509_crt_fmt_t type
                   is PEM or DER

DESCRIPTION         top

       This function sets a certificate/private key pair in the
       gnutls_certificate_credentials_t type.  This function may be called
       more than once, in case multiple keys/certificates exist for the
       server.  For clients that need to send more than its own end entity
       certificate, e.g., also an intermediate CA cert, then the
        certfile must contain the ordered certificate chain.

       Note that the names in the certificate provided will be considered
       when selecting the appropriate certificate to use (in case of
       multiple certificate/key pairs).

       This function can also accept URLs at  keyfile and  certfile . In
       that case it will use the private key and certificate indicated by
       the URLs. Note that the supported URLs are the ones indicated by

       In case the  certfile is provided as a PKCS 11 URL, then the
       certificate, and its present issuers in the token are imported (i.e.,
       forming the required trust chain).

       If that function fails to load the  res structure is at an undefined
       state, it must not be reused to load other keys or certificates.

       Note that, this function by default returns zero on success and a
       negative value on error.  Since 3.5.6, when the flag
       GNUTLS_CERTIFICATE_API_V2 is set using gnutls_certificate_set_flags()
       it returns an index (greater or equal to zero). That index can be
       used to other functions to refer to the added key-pair.

RETURNS         top

       On success this functions returns zero, and otherwise a negative
       value on error (see above for modifying that behavior).
