NAME

gnutls_pubkey_verify_hash2 - API function

CONTENTS

Synopsis
Arguments
Copyright

SYNOPSIS

#include <gnutls/abstract.h>

int gnutls_pubkey_verify_hash2(gnutls_pubkey_t key, gnutls_sign_algorithm_t algo, unsigned int flags, const gnutls_datum_t * hash, const gnutls_datum_t * signature);

ARGUMENTS

gnutls_pubkey_t key 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 * hash holds the hash digest to be verified
const gnutls_datum_t * signature contains the signature

DESCRIPTION

This function will verify the given signed digest, using the parameters from the public key. Note that unlike gnutls_privkey_sign_hash(), this function accepts a signature algorithm instead of a digest algorithm. You can use gnutls_pk_to_sign() to get the appropriate value.

RETURNS

In case of a verification failure GNUTLS_E_PK_SIG_VERIFY_FAILED is returned, and zero or positive code on success.

SINCE

3.0
