ROCKEY4ND is a driverless dongle that needs not a driver. The operating system has embedded the driver for ROCKEY4ND inside the system.

ROCKEY4ND is an advanced software protection system that attaches to the USB port of a computer. Your software may be duplicated, but it will only run when your ROCKEY4ND dongle is attached to the computer. It can also limit the use of your software. Your application will interact with ROCKEY4ND at start-up and during runtime. If the dongle has been removed, or if an application module has been accessed a preset number of times, it can issue an error message and terminate, or take other actions to insure compliance with your licensing agreement. ROCKEY4ND is versatile enough to support other limits as well.

100% Compatible with old ROCKEY4 dongle!
ROCKEY4ND can be seamlessly migrated from ROCKEY4 without the need to modify source code. All API's are the same except the dll/lib files, just replace the new dll/lib files.



Unlike some competing products, ROCKEY4ND is a powerful miniature computer, with a CPU, memory and specialized firmware that allow for robust interaction with your application. You may write complex algorithms that are securely stored in the dongle, and then call those algorithms from time-to-time in your application. This method for software protection is strongly recommended and is very difficult to crack. And though ROCKEY4ND was designed to implement extremely high levels of security, it is also relatively easy to implement. The ROCKEY4ND API set has been simplified and improved based on experience gained from earlier versions.

The ROCKEY4ND dongle provides protection not only for 32-bit applications running on
64-bit operating system, but also for 64-bit native applications.

The ROCKEY4ND dongle also provides envelope programs for .Net, flash media (.swf) applications. Another ROCKEY4ND enveloper will also encrypt Windows Portable Executable files (such as .dll, .exe and .arx) and is simple enough to implement in only a few seconds.

The ROCKEY4ND enveloper is an ideal solution if you do not possess the source code for your application, or are unfamiliar with implementing an API. A security system that combines both the API set and the Envelope program will offer the greatest level of protection.

ROCKEY4ND remote update provide useful tool that developer can create a secure patch file to update the ROCKEY4ND dongle remotely. All the content will be encrypted with DES and will only be decrypted with the valid ROCKEY4ND dongle. With this tool, developer can simply re-enable the dongle, open more functions or re-license the dongle, etc.


  • Compact Design – The USB dongle is one of the smallest in the world. The USB dongle is 50mm x 17mm x 7mm.
  • High Speed – ROCKEY4ND was designed to process even very complex algorithms with minimal delay for your application. Users will typically notice no performance hit as a result of a ROCKY4 implementation.
  • Ease of Use – Keeping the users in mind, ROCKY4’s reduced API set simplifies the programming effort and the Envelope program has also been improved with the release of ROCKEY4ND. The developers will get familiar with how to use the ROCKEY4ND dongles in a short time, and save your time spending on software protection.
  • High Security Levels – Redesigned ROCKEY4ND can reach a much higher security level. ROCKEY4ND implements a two level security system to segregate users who need read access only from those who need administrative privileges. ROCKEY4ND has a built in time gate to prevent software tracking and is powerful enough to support developer defined algorithms that can bring software protection to a new level of security.
  • High Reliability – RS-Computer employs an advanced customers managing system for ROCKEY4ND; we guarantee that the password of every customer is unique. And the hardware ID of every dongle is also unique. The password and hardware ID are burnt into the CPU, it is absolutely impossible to change them, even for us, the manufacturer.
  • Broad Support for Operating Systems – ROCKEY4ND protected applications may run on: Windows 98SE/ME/2000 /XP/Vista/7/2003/2008; Linux; MAC.
  • Abundant Programming Language Interfaces – ROCKEY4ND provides interfaces for these common development tools: PB, DELPHI, .Net, Java, Foxpro, VFP, VB, VC, C++ builder and more...
