C++ (Cpp) CHECK_AES_KEYSIZE Beispiele

Beispiel #1

Datei: aes-cbc-x86-aesni.c Projekt: gnutls/gnutls

static int
aes_cipher_setkey(void *_ctx, const void *userkey, size_t keysize)
{
	struct aes_ctx *ctx = _ctx;
	int ret;

	CHECK_AES_KEYSIZE(keysize);

	if (ctx->enc)
		ret =
		    aesni_set_encrypt_key(userkey, keysize * 8,
					  ALIGN16(&ctx->expanded_key));
	else
		ret =
		    aesni_set_decrypt_key(userkey, keysize * 8,
					  ALIGN16(&ctx->expanded_key));

	if (ret != 0)
		return gnutls_assert_val(GNUTLS_E_ENCRYPTION_FAILED);

	return 0;
}

Beispiel #2

Datei: aes-gcm-aarch64.c Projekt: ShiftMediaProject/gnutls

static int

{
	struct aes_gcm_ctx *ctx = _ctx;
	int ret;

	CHECK_AES_KEYSIZE(keysize);

	ret =
	    aes_v8_set_encrypt_key(userkey, keysize * 8,
				  ALIGN16(&ctx->expanded_key));
	if (ret != 0)
		return gnutls_assert_val(GNUTLS_E_ENCRYPTION_FAILED);

	aes_v8_encrypt(ctx->gcm.H.c, ctx->gcm.H.c, ALIGN16(&ctx->expanded_key));

	ctx->gcm.H.u[0] = bswap_64(ctx->gcm.H.u[0]);

	gcm_init_v8(ctx->gcm.Htable, ctx->gcm.H.u);

	return 0;
