An encoded file that requires a license will run only with a license created using the same Zend Guard as the file was encoded with. When a file is encoded by Zend Guard with support for licensing, it is digitally signed with a private key, which is unique to each and every Zend Guard installation. Each license file that is generated by Zend Guard is also digitally signed in a similar manner. When a user wants to run a file which has licensing requirements, he must use a license file that was generated by the same Zend Guard, otherwise the signatures will not match, and the license file will be considered invalid.
