NAME         top

       gnutls_ocsp_resp_verify_direct - API function

SYNOPSIS         top

       #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         top

       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         top

       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         top

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