.Net Exe Code & Dll Protection Solution

Combine .Net dll along with the exe and thus secure the dll also from reverse engineering.

AuthGuru .NET code protector encrypts the .Net exe code and dll which makes it extremely difficult to reverse engineer the application. Obfuscation is one way, but it can't protect from breaking the piracy protection security of the application. So how do you make sure that the application is not tampered with, and how do you make sure that the registration mechanism can't be reverse engineered? One way is to convert the C# application to native code and AuthGuru .Net code protector does that for you. Apart from converting the code to native code it also encrypts the code using 256 bit AES encryption. Combine .Net dll along with the exe and thus secure the dll also from reverse engineering.

Application Licensing

Unlike other protection solution, we do not force to implement the .Net application protection with the licensing. It is purely on to developer’s choice if they wish to use our licensing solution also. However, we offer multiple licensing keys, software and hardware based as per application usage.

  • AES 256bit encryption enhances security by encrypting exe code
  • Exe code is not decrypted using disassemblers
  • Apply protection with or without licensing
  • Protect unlimited applications after purchasing subscription
  • Secure your .NET applications and .NET libraries
  • Merge assemblies into one executable or library
  • Removes IL code
  • Native Exe file generation
  • Protection against disassembling and hacking
  • Protects any kind of .NET assembly
  • Replace CIL code with native code

Software developers are able to protect their software in just few clicks now without having to make any change in their existing code. These way developers can focus more on development than on worrying how to protect their intellectual property. In contrast to obfuscators it completely stops any decompiling by mixing any pure .Net assembly (written in C#, VB.NET, Delphi.NET...) with native machine code. In detail, it builds a native wall between potential hackers and your .Net code. The result is a standard Windows based, not MSIL compatible, file.

The original .Net code remains intact, well protected by native code and invisible for prying eyes. The original .Net code is not copied on hard disk at any time. The code also gets encrypted after being converted to native code with 256 bit AES encryption and is decrypted in memory during runtime which makes it extremely secure.

Watch this demo, how to protect a .Net application exe along with dll file. Unlike other software which only obfuscates the code, .Net code protector for .Net applications uses Black-box encryption algorithm to encrypt the code of .Net application exe which makes reverse engineering almost impossible using disassemblers. Normally code of an exe can be rad or extracted using .Net Reflector or other disassemblers.

Why you need to protect your .Net exe and dll?

When you compile a program written for the Microsoft .NET framework, the program you provide to your users is not compiled into a native executable program, but instead is translated into something called the Common Intermediate Language instructions (CIL). CIL is half way between source code and native code, and is interpreted by the .NET framework when your program is run, rather than executed directly as machine code. Because of this, the source code of your application or library can be easily reproduced. Tools such as .NET Reflector (www.red-gate.com/products/reflector/) can reproduce source code from compiled .NET assemblies in seconds, and in the .NET language of your choice! Clearly, commercial software distributed to end users without some form of protection is wide open to piracy and intellectual property theft. The traditional solution to intellectual property protection in .NET is to use 'obfuscation', indeed Microsoft makes an obfuscation utility available to Visual Studio users.

Why is obfuscation not enough?

Obfuscation is the process of making your source code more difficult (but not impossible) for humans to understand. Obfuscation works by replacing the meaningful names you assign to classes, methods, properties and variables with meaningless ones. For example, it may replace a variable name of "counter" with "A4DF3CV89G" - to humans these obfuscated names are confusing and difficult to remember, but have no effect on the NET Framework interpreter. Note that obfuscation does nothing to the source code within your methods, so it is not protected at all by obfuscation. .NET Reactor does everything an obfuscator does, but then wraps your intellectual property in several more layers of protection, denying access to your source code to even those who are determined to steal your hard work. .NET Reactor's protection has never been cracked, something which cannot be said about obfuscators.

Industry leading Authguru .Net code protector

It prevents de-compilation by a variety of methods which convert your .NET assemblies into processes which no existing tool can de-compile ( and which are also very likely to prevent decompilation by any future tool). .NET code protector builds a native code wall between potential hackers and your .NET assemblies by producing a file which cannot be understood directly as CIL. Because the CIL in your assembly is emitted intact only at run time or design time (in a form in which the source is completely inaccessible).
