C++ (Cpp) crypt_hmac_restart Beispiele

Beispiel #1

Datei: crypto_nettle.c Projekt: PoganyyDr0cher/cryptsetup

int crypt_hmac_final(struct crypt_hmac *ctx, char *buffer, size_t length)
{
	if (length > (size_t)ctx->hash->length)
		return -EINVAL;

	ctx->hash->hmac_digest(&ctx->nettle_ctx, length, (uint8_t *)buffer);
	crypt_hmac_restart(ctx);
	return 0;
}

Beispiel #2

Datei: crypto_gcrypt.c Projekt: Distrotech/cryptsetup

int crypt_hmac_final(struct crypt_hmac *ctx, char *buffer, size_t length)
{
	unsigned char *hash;

	if (length > (size_t)ctx->hash_len)
		return -EINVAL;

	hash = gcry_md_read(ctx->hd, ctx->hash_id);
	if (!hash)
		return -EINVAL;

	memcpy(buffer, hash, length);
	crypt_hmac_restart(ctx);

	return 0;
}

Beispiel #3

	if (length > (size_t)ctx->hash_len)
		return -EINVAL;

	HMAC_Final(&ctx->md, tmp, &tmp_len);
