python-yubico
Python package for talking to YubiKeys.
Introduction
The YubiKey is a hardware token for authentication. The main mode of the YubiKey is entering a one time password (or a strong static password) by acting as a USB HID device, but there are things one can do with bi-directional communication:
-
Configuration. The yubikey_config class should be a feature-wise complete implementation of everything that can be configured on YubiKeys version 1.3 to 3.x (besides deprecated functions in YubiKey 1.x). See
examples/configure_nist_test_key
for an example. -
Challenge-response. YubiKey 2.2 and later supports HMAC-SHA1 or Yubico challenge-response operations. See
examples/nist_challenge_response
for an example.
This library makes it easy to use these two features.
Example
Here is a trivial usage example :
#!/usr/bin/env python
""" Get version of connected YubiKey. """
import sys
import yubico
try:
yubikey = yubico.find_yubikey(debug=False)
print("Version: {}".format(yubikey.version()))
except yubico.yubico_exception.YubicoError as e:
print("ERROR: {}".format(e.reason))
sys.exit(1)
Installation
Using the Ubuntu/Debian package manager
If you use a recent Ubuntu release, you should be able to install python-yubico with these commands :
$ sudo add-apt-repository ppa:yubico/stable $ sudo apt-get update $ sudo apt-get install python-yubico
The Launchpad PPA key generated for our packages is 32CBA1A9.
Using Pip
python-yubico is installable via pip:
$ pip install python-yubico
Using Setup
Or, directly from the source package in the standard Python way:
$ cd python-yubico-$ver $ python setup.py install
This requires the python-setuptools
package.
On Windows
If you use Windows, you will require a PyUSB backend. Python-yubico has been tested with libusbx and confirmed working, without the need for replacing the device driver.
