Using SourceGuardian protected files

Encoded scripts protected by SourceGuardian require installing loaders in order to run. You can find these loaders below for SourceGuardian 17. The same loaders can run files protected with SourceGuardian version 8 to 17.

SourceGuardian loaders differ for OS, platform and version of PHP. We strongly recommend that you use our online SourceGuardian loader assistant to know the loader you need for your system and how to install it. You will need to enter a link to the phpinfo() page running on your server or paste its contents if your system is not online.

Manually download loaders for SourceGuardian 8 - 17 for PHP(PHP versions from 5.3 PHP to 8.5 are fully supported)

To download any of our loaders, please accept the terms and conditions

"SourceGuardian is essential to my business. It enables my product to be flexible, and yet keep the intellectually important stuff safe. This is important for my school virtual learning environment product as schools are all different, wanting different things from their VLE. Our product gives them a framework of functionality (the SourceGuardian encrypted stuff), but allows them to customise the rest."
