Arduino Random Password Generator

An hardware for random password generation that uses human inputs to generate a seed and can copy the generated password as keyboard.

It has been made using an Arduino Pro Micro, that can actually emulate a Keyboard.

Unfortunately all the (functioning) interrupts were occupied by the display, so I had to be a little bit creative with the code.

Features

• Seed generation and improvement. The seed is an unsigned long int, and it is modified using addition and/or multiplicationaccording to how many times and for how long a button is pressed.
• Alphanumeric password or with symbols. Passwords are 256 character long.
• Password copy to any compatible device. After it has been generated, the password can be copied to any computer that supports HID keyboard.

To do

• Asymmetric authentication to check if the device has been messed with. Requires an HTTPS web server or a trusted desktop application.
