API function


#include <gnutls/gnutls.h>

int gnutls_certificate_set_ocsp_status_request_file(gnutls_certificate_credentials_t sc, const char * response_file, unsigned idx);


gnutls_certificate_credentials_t sc

is a credentials structure.

const char * response_file

a filename of the OCSP response

unsigned idx

is a certificate index as returned by gnutls_certificate_set_key() and friends


This function loads the provided OCSP response. It will be sent to the client if requests an OCSP certificate status for the certificate chain specified by  idx .


the ability to set multiple OCSP responses per credential structure via the index  idx was added in version 3.5.6. To keep backwards compatibility, it requires using gnutls_certificate_set_flags() with the GNUTLS_CERTIFICATE_API_V2 flag to make the set certificate functions return an index usable by this function.

This function can be called multiple times since GnuTLS 3.6.3 when multiple responses which apply to the chain are available. If the response provided does not match any certificates present in the chain, the code GNUTLS_E_OCSP_MISMATCH_WITH_CERTS is returned. To revert to the previous behavior set the flag GNUTLS_CERTIFICATE_SKIP_OCSP_RESPONSE_CHECK in the certificate credentials structure. In that case, only the end-certificate's OCSP response can be set. If the response is already expired at the time of loading the code GNUTLS_E_EXPIRED is returned.

To revert to the previous behavior of this function which does not return any errors, set the flag GNUTLS_CERTIFICATE_SKIP_OCSP_RESPONSE_CHECK


On success, GNUTLS_E_SUCCESS (0) is returned, otherwise a negative error code is returned.
