[ Thanks to An Anonymous Reader for this link. ]

"For a good couple of years now I've wondered if there was a way to write an authentication system in PHP that utilized SSH instead of the widely-breakable database and flatfile methods. After doing some research I found its possible after installing a PHP extension. This guide will detail the methods used to do this, with the intent of hopefully having this a more versatile option.

:Requirements: Before we begin, there are a few things that are needed. The first is obviously PHP, with this guide written for 5.3.6. My system has Suhosin already installed and it causes no issues so you should be fine too if you have those patches installed. The next thing you'll need is the PECL extension SSH2. There other libraries out there that you can use that people have written but I decided to stick with officially supported releases."
