gnutls_certificate_set_x509_key_file - API function


#include <gnutls/gnutls.h>

int gnutls_certificate_set_x509_key_file(gnutls_certificate_credentials_t res, const char * certfile, const char * keyfile, gnutls_x509_crt_fmt_t type);


gnutls_certificate_credentials_t res
is a gnutls_certificate_credentials_t structure.
const char * certfile
is a file that containing the certificate list (path) for the specified private key, in PKCS7 format, or a list of certificates
const char * keyfile
is a file that contains the private key
gnutls_x509_crt_fmt_t type
is PEM or DER


This function sets a certificate/private key pair in the gnutls_certificate_credentials_t structure. 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 import the private key and certificate indicated by the URLs. Note that the supported URLs are the ones indicated by gnutls_url_is_supported().

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


GNUTLS_E_SUCCESS (0) on success, or a negative error code.
