SourceGuardian Loader is a software component used to decrypt and execute PHP files that have been encoded with SourceGuardian, a popular PHP encoder. SourceGuardian is a commercial product that offers a way to protect PHP source code by converting it into a binary format that is difficult to reverse-engineer.
When PHP files are encoded with SourceGuardian, they are transformed into bytecode that can only be executed with the help of the SourceGuardian Loader. The Loader acts as a runtime module that needs to be installed on the server where the PHP files will be executed.
The SourceGuardian Loader decrypts the encoded PHP files on-the-fly and makes them executable by the PHP engine. This allows the server to run the protected PHP code, while still maintaining the security provided by SourceGuardian’s encryption.
Using an encoder like SourceGuardian can help protect sensitive or proprietary PHP code from being easily understood or modified by unauthorized individuals. The Loader is necessary to ensure that the encoded PHP files can be executed on the server while preserving their encrypted state.
It’s important to note that the SourceGuardian Loader is specific to the SourceGuardian PHP encoder and cannot be used with other PHP encoders or encryption methods. Additionally, the Loader is typically provided by the SourceGuardian vendor and should be obtained from them to ensure compatibility and licensing compliance.
