Key is a lightweight and reliable PHP class that helps you protect any page in seconds, with support for multiple users, MD5 and SHA1 hashing, and no database necessary!
Protecting a page with Key is as simple as including a tiny snippet of code at the top of the page you’d like to protect – and it takes care of everything else for you!
If you’re a developer, Key is very well documented and easy to extend or modify. Key’s code is documented with phpdoc-standard tags, and includes extensive and clear HTML documentation, for both end-users and developers.
