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.
