Safengine provides a powerful virtual machine to protect your applications against reverse engineering or unwanted modifications. The protector will convert your sensitive code (in x86 assembly) into a random instruction set which can only be executed by the virtual machine interpreter embedded into your application after protection. These virtual machines are very unique, fully randomized and heavily obfuscated.

During the virtualization process, your original code flow will be redirected with logical obfuscation, there will be no more than a NAND operation in the virtual machine to emulate logical operations such as AND, OR, NOT and XOR, while most arithmetical operations will be implemented via ADD so that it is very hard for a reverse engineer to tell how the original code works. Also, there will be no “conditional jump” instructions after virtualization, which makes crackers have no place to manipulate the execution flow.

Safengine NetLicensor

Based on Safengine Licensor, we proudly announce our remote license authorization system:
Safengine NetLicensor
With the combination of:
  • Safengine Code Protection(Mutation & Virtualization)
  • Safengine Licensor Local License Verification
  • Safengine NetLicensor Remote License Verification

Remote License Verification

Applications protected by Safengine NetLicensor will connect to NetLicenser Server at startup for license key verification, while all trial time & date control are server based.
Safengine NetLicensor can easily eliminate the following problems:
  1. Leakage of valid license keys
  2. System time out of sync
  3. Unauthorized sharing of license keys
  4. Banning licenses on demand
Safengine NetLicensor Server uses MySQL as database server, which, in most cases, can easily integrate into existing server platforms. The server architecture has been fully tested with all Safengine products since version 1.7, ensuring its outstanding stability and minimum resource usage.
