gnutls_pubkey_verify_hash2 (3)

#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);

gnutls_pubkey_t key

Holds the public key

gnutls_sign_algorithm_t algo

The signature algorithm used

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

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.

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