Here you can find my other arduino projects.For my 3D printing host app I need to encrypt some data while send over network, then decrypt on server side that receive over the network and send to the 3D Printer over USB.įor this purpose I've used a Raspberry PI Zero W that acts as WiFi-Serial bridge to remotely control a 3D printer.īecause I had necessity to adapt to ESP8266 and ESP32 (instead of Raspberry), I never used B4XEncryption and tried to use a sort of simple algorithm XORing all strings I send. Other version non arduino of the DES algorithm by Daniel Otte.

There is a very good excel version of such a process which visualizes the whole process that can be downloaded from the bottom of the link above. There are other encryption techniques such as AES etc used which can be seen here. V = v & mask // truncate v to specified number of places while(num_places) Void print_binary(uint64_t v, int num_places) Showprint = 'Plain 64 bits = ' printout1(0,8) Showprint = 'LR 64 bits = ' printout2(0,8)
