gnutls_ocsp_resp_verify_direct(3)

NAME
gnutls_ocsp_resp_verify_direct - API function

SYNOPSIS
#include <gnutls/ocsp.h>

int gnutls_ocsp_resp_verify_direct(gnutls_ocsp_resp_const_t resp, gnutls_x509_crt_t issuer, unsigned int * verify, unsigned int flags);

ARGUMENTS

gnutls_ocsp_resp_const_t resp
    should contain a gnutls_ocsp_resp_t type

gnutls_x509_crt_t issuer
    certificate believed to have signed the response

unsigned int * verify
    output variable with verification status, an gnutls_ocsp_verify_reason_t

unsigned int flags
    verification flags from gnutls_certificate_verify_flags

DESCRIPTION
Verify signature of the Basic OCSP Response against the public key in the issuer certificate. 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.

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