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.
