Cipherbox is what I consider to be a cryptographic swiss knife. It utilizes six encryption algorithms, and it's also a vault that's locked with four RFID cards, your username, and password.
Cipherbox V1.0 consists of three microcontrollers: ESP32, Arduino Uno, and ESP8266.
Cipherbox V2.0 consists of four microcontrollers: ESP32, Arduino Uno, ESP8266, and Arduino Nano (or any compatible board).
Cipherbox V3.0 consists of two microcontrollers: ESP32, and Arduino UNO.
