NAME

       gnutls_ocsp_resp_verify - API function


SYNOPSIS

       #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

       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

       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

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