gnutls_ocsp_resp_verify(3) gnutls gnutls_ocsp_resp_verify(3)
gnutls_ocsp_resp_verify - API function
#include <gnutls/ocsp.h>
int gnutls_ocsp_resp_verify(gnutls_ocsp_resp_const_t resp,
gnutls_x509_trust_list_t trustlist, unsigned int * verify,
unsigned int flags);
gnutls_ocsp_resp_const_t resp
should contain a gnutls_ocsp_resp_t type
gnutls_x509_trust_list_t trustlist
trust anchors as a gnutls_x509_trust_list_t type
unsigned int * verify
output variable with verification status, an
gnutls_ocsp_verify_reason_t
unsigned int flags
verification flags from
gnutls_certificate_verify_flags
Verify signature of the Basic OCSP Response against the public key
in the certificate of a trusted signer. The trustlist should be
populated with trust anchors. The function will extract the
signer certificate from the Basic OCSP Response and will verify it
against the trustlist . A trusted signer is a certificate that
is either in trustlist , or it is signed directly by a
certificate in
trustlist and has the id-ad-ocspSigning Extended Key Usage bit
set.
The output verify variable will hold verification status codes
(e.g., GNUTLS_OCSP_VERIFY_SIGNER_NOT_FOUND,
GNUTLS_OCSP_VERIFY_INSECURE_ALGORITHM) which are only valid if the
function returned GNUTLS_E_SUCCESS.
Note that the function returns GNUTLS_E_SUCCESS even when
verification failed. The caller must always inspect the verify
variable to find out the verification status.
The flags variable should be 0 for now.
On success, GNUTLS_E_SUCCESS (0) is returned, otherwise a negative
error value.
