Introduction to AutoCrypt SL

AutoCrypt SL was developed by MARX in partnership with SoftwareKey. It can protect your software quickly and effortlessly, without writing a single line of code and without needing access to the source code. Your protected application will connect to Softwarekey's SOLO Server for automated online activation and validation.

AutoCrypt SL Features

  • Wraps your existing application and adds a secure layer of protection.
  • Supports protection of Windows 32/64 bit executables and DLLs.
  • Supports protection of .NET executables.
  • Provides many licensing scenarios for creative distribution strategies, such as limited trial versions, permanent licenses or subscriptions.
