b-eriksson / v2f.py

A virtual U2F device implementation that lets you try, study, and hack U2F

WARNING:

This project is still in its pre-alpha stage. Serious refactoring and documentations are needed.

Currently v2f.py only supports Linux and Python 3.5+. The code was tested using Google Chrome inside a 64-bit Ubuntu 16.04 desktop environment.

v2f.py is a virtual U2F device

Clone this source code repository

git clone https://github.com/concise/v2f.py
cd v2f.py

Tweak permissions of some files before running v2f, which needs uhid and hidraw. An easy way to do that is just making /dev/uhid and /dev/hidraw* device nodes universally read-writable

sudo bash hack-linux-for-v2f

Run v2f (default: store everything under ~/.v2f directory)

python3 v2f.py

Run v2f with a specified device information directory

python3 v2f.py ~/.my-v2f-info-dir
