.NET Reactor is a powerful .NET code protection & licensing system which assists developers in protecting their .NET software. Developers are able to protect their software in a safe and simple way now. This way developers can focus more on development than on worrying how to protect their intellectual property.

In contrast to obfuscators .NET Reactor completely stops any decompiling by mixing any pure .NET assembly (written in C#, VB.NET, Delphi.NET, J#, MSIL...) with native machine code. In detail, .NET Reactor 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 harddisk at any time. There is no tool which is able to decompile .NET Reactor protected assemblies.
