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
