/* * The MySensors Arduino library handles the wireless radio link and protocol * between your home built sensors/actuators and HA controller of choice. * The sensors forms a self healing radio network with optional repeaters. Each * repeater and gateway builds a routing tables in EEPROM which keeps track of the * network topology allowing messages to be routed to nodes. * * Created by Henrik Ekblad * Copyright (C) 2013-2026 Sensnology AB * Full contributor list: https://github.com/mysensors/MySensors/graphs/contributors * * Documentation: http://www.mysensors.org * Support Forum: http://forum.mysensors.org * * This program is free software; you can redistribute it and/or * modify it under the terms of the GNU General Public License * version 2 as published by the Free Software Foundation. */ #include "MyCryptoGeneric.h" void SHA256HMAC(uint8_t *dest, const uint8_t *key, size_t keyLength, const uint8_t *data, size_t dataLength) { SHA256HMACInit(key, keyLength); SHA256HMACAdd(data, dataLength); SHA256HMACResult(dest); } AES _aes; void AES128CBCInit(const uint8_t *key) { _aes.set_key((byte *)key, 16); } void AES128CBCEncrypt(uint8_t *iv, uint8_t *buffer, const size_t dataLength) { _aes.cbc_encrypt((byte *)buffer, (byte *)buffer, dataLength / 16, iv); } void AES128CBCDecrypt(uint8_t *iv, uint8_t *buffer, const size_t dataLength) { _aes.cbc_decrypt((byte *)buffer, (byte *)buffer, dataLength / 16, iv); }
