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/

Purpose

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.
