gnutls_ocsp_resp_verify - API function
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.
