NAME

       gnutls_pubkey_verify_data2 - API function

SYNOPSIS

       #include <gnutls/abstract.h>

       int   gnutls_pubkey_verify_data2(gnutls_pubkey_t   pubkey,  gnutls_sign_algorithm_t  algo,
       unsigned int flags, const gnutls_datum_t * data, const gnutls_datum_t * signature);

ARGUMENTS

       gnutls_pubkey_t pubkey
                   Holds the public key

       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. For known to be insecure signatures this  function  will  return
       GNUTLS_E_INSUFFICIENT_SECURITY unless the flag GNUTLS_VERIFY_ALLOW_BROKEN is specified.

SINCE

       3.0
