Usage

#include <gnutls/abstract.h>

int gnutls_pubkey_verify_hash(gnutls_pubkey_t key, unsigned int flags, const gnutls_datum_t * hash, const gnutls_datum_t * signature);

Arguments

`gnutls_pubkey_t key`	Holds the public key
`unsigned int flags`	Zero or one of `gnutls_pubkey_flags_t`
`const gnutls_datum_t * hash`	holds the hash digest to be verified
`const gnutls_datum_t * signature`	contains the signature

Overview

This function will verify the given signed digest, using the parameters from the public key.

Deprecated. This function cannot be easily used securely. Use gnutls_pubkey_verify_hash2() instead.

Returns

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