This key has been inspired by this project : https://codeandlife.com/2012/03/03/diy-usb-password-generator/ It makes an extensive use of the library V-USB distributed here (under GNU GPL2 or GPL3) : http://www.obdev.at/vusb/
The USB key has been designed to generate, store, type and delete a password using an unexpensive Atmel Attiny85 chip. It mimics the behavior of an USB keyboard, which makes it (almost) universal and driverless.
A short press on the button allow the key to type the stored password. A long press (5 seconds) on the button resets the stored password.
For more complex operations, the python script commandline.py must be used while the key is plugged.
Refer to the following drawing to build the key. Then flash it with the given driver (e. g. using ISP).
