ACLib Protect (AProtect) application encrypts parts of code between the encrypt_start and encrypt_stop blocks using a license file.
License file is a standard ASCII file and can be modified as long as the 17 lines long AProtect block is not modified. You can add any extra data before or after the block (i.e. user name and extra registration data). Usage of AProtect is very simple. Select input file, output file and license and press Protect File button. You can also save the project using the File menu. File menu also allows you to create new License Files.
