NAME         top

       gnutls_ocsp_resp_verify - API function

SYNOPSIS         top

       #include <gnutls/ocsp.h>

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

ARGUMENTS         top

       gnutls_ocsp_resp_const_t resp
                   should contain a gnutls_ocsp_resp_t type

       gnutls_x509_trust_list_t trustlist
                   trust anchors as a gnutls_x509_trust_list_t type

       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 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_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.
