Library for developing U2F devices
This library is meant to be portable across devices and protocols.
- HID, via hiddev library
The library has been designed to also support Bluetooth and NFC, but those haven't been implemented yet.
I've used these other implementations as references to make mine:
- teensy-u2f - Teensy LC U2F key implementation
- v2f.py - A virtual U2F device implementation that lets you try, study, and hack U2F
- stm32-u2f - A Universal 2nd Factor (U2F) USB token using STM32 MCUs
