gnutls_pubkey_verify_hash - API function
SYNOPSIS
#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 on 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
DESCRIPTION
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.
