4.2.1. Overview of Libraries and Modules

The official OpenID Foundation website offers a list of OpenID 2.0 protocol implementations in several programming languages (see Libraries for Obsolete Specifications).

We offer examples of implementation for PHP (ZIP, 140 kB) and Java (ZIP, 3,5 MB).


The examples of implementation cannot be simply installed and run. They will not work with your system as they are. They are meant to serve as an example for creating your own implementation.

Then, for a few most popular open-source platforms, there are modules that we have created to make implementation to these systems easier:

We also have a few more in our archives (WordPress, VirtueMart, phpBB, Opencart, osCommerce, Redmine, Zencart) and we are happy to provide them if you ask our support team (techsupport@mojeid.cz).


We inform you that you can use modules only at your own risk and the CZ.NIC Association is not subject to any liability for any damage.
