=== Introduction ===
Serverside U2F library for PHP. Provides functionality for registering
tokens and authentication with said tokens.
To read more about U2F and how to use a U2F library, visit
link:http://developers.yubico.com/U2F[developers.yubico.com/U2F].
=== License ===
The project is licensed under a BSD license. See the file COPYING for
exact wording. For any copyright year range specified as YYYY-ZZZZ in
this package note that the range specifies every single year in that
closed interval.
=== Dependencies ===
The only dependency is the openssl extension to PHP that has to be enabled.
A composer.json is included in the distribution to make things simpler for
other project using composer.
=== Tests ===
To run the test suite link:https://phpunit.de[PHPUnit] is required. To run it, type:
$ phpunit
