northstrix / des_and_3des_library_for_mcus

DES and Triples DES encryption and decryption for the ESP8266, ESP32, Raspberry Pi Pico, STM32, and any compatible board.

Changes in the fork DES_and_3DES_Library_for_MCUs by Northstrix:

1. Made it compatible with the ESP32, Raspberry Pi Pico, and STM32F103C8T6 by removing several unused lines;
2. Removed unused examples and added the new ones.

DES_Library

This project is a fork from ArduinoDES project that implements a DES and Triple DES encryption and decryption library for the Arduino and Rpi.

I've made some changes so that this library can be used and compiled in ESP8266 Sming Framework based projects.

For the original library and instructions, please refer to https://github.com/Octoate/ArduinoDES.git

Usage

It is possible to encrypt and decrypt messages with the DES or Triples DES crypto algorithms. Have a look at the example code for more information.

To use in Sming framework, just copy the DES.cpp file for the app directory, and the include files DES.h and DES_config.h for the include directory.

On the main application include the DES.h file, and the encryption and decryption API is now available.

#include <SmingCore/SmingCore.h>
#include <DES.h>

Under the directory examples_ESP8266 there is a example *application.cpp file that mimics the original example.
