The ultimate edition of VMProtect allows you to add serial numbers to the protected application with minimal effort. The feature is supported by PayPro Global e-commerce provider, so you do not even need to set up your own serial number generator (of course, you can do that if you really need it). The licensing feature allows you to limit the period of free updates, set the time of life of a serial number, prevent code execution without serial numbers and much more. Any serial number can be blocked and newly protected files will not accept it.
VMProtect features two modes of the user interface: simple and expert. Simple mode allows you to easily pick functions for protection, adjust options and get a protected file with just a few mouse clicks.
“Mutation” protection method
Mutations are a replacement for the source code instructions with their analog (or a certain instruction sequence), which give the same result as the source code. It is the fastest yet simpleest way of software protection. Quite useful when you need to hide the signatures of third-party libraries used in your code. For example, if a hacker knows that you use a well-known SHA-1 implementation, he may attack it instead of your code. Mutation allows to hide the presence of the library.
Virtualization protection method
Virtualization is the process of translating the executable code into the instructions of a virtual machine with the different architecture, which is unknown to a potential cracker. Virtualized parts of the code are executed by the interpreter (virtual machine) without being converted into native machine code. Generally, the reengineering of virtualized code requires the study of virtual machine architecture first, then it requires the creation of a disassembler that understands that architecture. Both processes are quite time consuming and stop a lot of crackers. Each time you protect the application, VMProtect generates a completely different set of virtual machines, so even if a cracker finally understands the architecture of the particular virtual machine, he must start from the very beginning of the second protected procedure of the same file.
“Ultra” protection method
Ultra combines virtualization and mutation methods to make protection even better. The protected code is mutated first and then the result is virtualized.
You can add serial numbers to your application with minimal effort. VMProtect provides a robust API that allows you to pass a serial number to the VMProtect’s internal module and then check its state.
Lock code to serial number
This feature allows you to prevent the execution of some code by the additional encryption. The key is not present in the protected application and the code can be encrypted only when the serial number is entered. However, even after that, the code is still virtualized, so there is no way to dump it after entering a valid serial number. This is an essential feature for creating demo versions of software.
Watermark is a unique sequence of bytes that can be added to a protected file. It allows unambiguous identification of the cracked software copy’s legal owner.
The Virtual Files feature allows you to bundle files inside the main executable, so your application with its plugins becomes a single file. This is useful for portable applications or if you want to hide some file or dynamic loading library.
Supported Files And Formats
VMProtect supports both 32 and 64-bit executable files, dynamically loaded libraries and drivers. This includes screensavers, Active-X components, BPL libraries and other files in PE-format. Protected files are running almost any version of Windows, even old Windows 95! However, the licensing feature requires at least Windows 2000. VMProtect does not support .NET executables.
