Team Password Manager is distributed as an encoded PHP application. The PHP source code is encoded (obfuscated) using the Sourceguardian PHP encoder.
The Sourceguardian PHP Loader (https://www.sourceguardian.com/loaders.html) is the software you need to read and execute PHP files encoded by Sourceguardian.
The Sourceguardian PHP Loader is free.
* Note: version 10.138.240 and lower used the Ioncube loader, which is a loader from a different company (Ioncube). Since v. 11.141.247 we use the Sourceguardian loader.
