YubiStack provides a python re-implementation of:

• yubiauth: Authentication client with a simple user management system
• yubikey-val: YubiKey validation server
• yubikey-ksm: YubiKey key storage module

NOTE: Only the authentication part is implemented from yubiauth, the user management system is NOT.

To install yubistack, simply:

$ sudo pip install yubistack

The configuration file path is read from YUBISTACK_SETTINGS environment variable, otherwise defaults to /etc/yubistack.conf. You can find a sample config in the repo.
