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