NAME
gnutls_pubkey_verify_data2 - API function
SYNOPSIS
#include <gnutls/abstract.h>
int gnutls_pubkey_verify_data2(gnutls_pubkey_t pubkey,

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
