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.
