NAME
       gnutls_ocsp_resp_verify - API function

SYNOPSIS
       #include <gnutls/ocsp.h>

       int  gnutls_ocsp_resp_verify(gnutls_ocsp_resp_t	resp, gnutls_x509_trust_list_t trustlist,
       unsigned int * verify, unsigned int flags);

ARGUMENTS
       gnutls_ocsp_resp_t resp
		   should contain a gnutls_ocsp_resp_t structure

       gnutls_x509_trust_list_t trustlist
		   trust anchors as a gnutls_x509_trust_list_t structure

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

       unsigned int flags
		   verification flags, 0 for now.

DESCRIPTION
       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_VER-
       IFY_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.
