SYNOPSIS

       #include <gnutls/x509.h>

       int   gnutls_x509_crt_verify_data2(gnutls_x509_crt_t  crt,  gnutls_sign_algorithm_t  algo,
       unsigned int flags, const gnutls_datum_t * data, const gnutls_datum_t * signature);

ARGUMENTS

       gnutls_x509_crt_t crt
                   Holds the certificate to verify with

       gnutls_sign_algorithm_t algo
                   The signature algorithm used

       unsigned int flags
                   Zero or an OR list of gnutls_certificate_verify_flags

       const gnutls_datum_t * data
                   holds the signed data

       const gnutls_datum_t * signature
                   contains the signature

DESCRIPTION

       This  function  will  verify  the  given  signed  data,  using  the  parameters  from  the
       certificate.

RETURNS

       In  case  of a verification failure GNUTLS_E_PK_SIG_VERIFY_FAILED is returned, and zero or
       positive code on success.
