@deftypefun {int} {gnutls_ocsp_resp_verify_direct} (gnutls_ocsp_resp_const_t @var{resp}, gnutls_x509_crt_t @var{issuer}, unsigned int * @var{verify}, unsigned int @var{flags})
@var{resp}: should contain a @code{gnutls_ocsp_resp_t}  type

@var{issuer}: certificate believed to have signed the response

@var{verify}: output variable with verification status, an @code{gnutls_ocsp_verify_reason_t} 

@var{flags}: verification flags from @code{gnutls_certificate_verify_flags} 

Verify signature of the Basic OCSP Response against the public key
in the  @code{issuer} certificate.

The output  @code{verify} variable will hold verification status codes
(e.g., @code{GNUTLS_OCSP_VERIFY_SIGNER_NOT_FOUND} ,
@code{GNUTLS_OCSP_VERIFY_INSECURE_ALGORITHM} ) which are only valid if the
function returned @code{GNUTLS_E_SUCCESS} .

Note that the function returns @code{GNUTLS_E_SUCCESS}  even when
verification failed.  The caller must always inspect the  @code{verify} variable to find out the verification status.

The  @code{flags} variable should be 0 for now.

@strong{Returns:} On success, @code{GNUTLS_E_SUCCESS}  (0) is returned, otherwise a
negative error value.
