64-bit Support
.NET Reactor supports 32-bit and 64-bit Assemblies.
img
Merging/Embedding
.NET Reactor can merge or embed multiple .NET files into one executable(.exe) or library(.dll).
img
Compression
.NET Reactor is able to compress applications and embedded files up to 50-75%.
img
NecroBit IL Code Protection
NecroBit is a powerful protection technology which stops decompilation. NecroBit replaces the CIL code within methods with encrypted code. This way it is not possible to decompile/reverse engineer your method source code.
img
Code Virtualization
Code Virtualization converts your code into a set of randomized intructions which are intepreted at runtime by a virtual machine. As other tools can't interprete the new instructions the original code can't be reconstructed.
img
Anti ILDASM / Anti Decompiler
No tool can disassemble/decompile .NET Reactor protected code. ILDASM(the Microsoft Intermediate Language disassembler) will actually report that it cannot interpret .NET Reactor protected assemblies.
img
Hide Method Calls
Hide calls to external and/or internal methods. Method calls are redirected through delegates which are dynamically built at runtime.
img
Anti Debug
This feature enables anti-debugger detections inside the protected assembly. In case a debugger is attached the current process will be terminated.
img
Native EXE File
.NET Reactor is able to generate a native x86 EXE file stub for your application. This way it is not possible to directly open your protected application in a decompiler. The decompiler recognizes your protected application as a native EXE file.
img
Pre-JIT Methods
In combination with the Native EXE File feature and NecroBit, .NET Reactor is able to convert managed methods into REAL x86 native code. Only methods which doesn't affect the runtime and platform behavior (mostly small methods like property getters/setters...) are converted into native code. By nature this feature has an built-in protection against assembly modification.
img
Obfuscation
In addition to source protection, .NET Reactor provides thorough class and member obfuscation complemented by different exclusion schemes, use of non-printable characters in obfuscated names, and even incremental obfuscation, which always generates the same obfuscation strings for type and member names.
img
Declarative Obfuscation
Declarative Obfuscation support allows you to directly define which types and members should be excluded from obfuscation. This can be done by using the custom attribute System.Reflection.ObfuscationAttribute in your source code. .NET Reactor automatically detects the attribute and excludes the corresponding types and members from obfuscation.
img
String Encryption
String encryption makes it difficult for a hacker to understand your code and to attempt a code patch of your assembly, as he will be unable to identify the text of messages or other useful strings, making it much more difficult to identify where to patch your code. This feature has a built-in protection against assembly manipulation.
img
Control Flow Obfuscation
Control Flow Obfuscation converts the code inside your methods into spaghetti code, which whilst retaining the function of the code makes it extremely difficult for human eyes and decompilers to follow the program logic. Decompilers are not able to decompile the spaghetti code back to your original source code.
img
Resource Encryption and Compression
.NET Reactor can improve protection and assembly size by compressing and encrypting your managed resources. At runtime, when required the resources are automatically decompressed and decrypted.
img
Strong Name Removal Protection
Strong Name Removal Protection prevents your protected assembly from being tampered by hacker tools as they are not able to correctly resign the assembly with a different stong name.
img
.NET Core Single File Deployment
Create .NET Core single file application bundles without increasing the size of your application.
img
Powerful Licensing System
Powerful and flexible, the .NET Reactor licensing features allow you to enforce your license conditions and protect your revenue stream by using hardware and software locks. The license manager can build trial or permanent licenses, in a matter of seconds. A fully documented software development kit (SDK), complete with examples, allows you to call the licensing system directly from your code, allowing you to create custom extensions to the licensing system.
img
Visual Studio Add-in
Automate compile time protection using the .NET Reactor Visual Studio Add-in.
img
Azure DevOps
Seamless integration in Azure DevOps with .NET Reactor DevOps pipeline tasks.
img
Third Party Support
.NET Reactor is a mature product. It protects your software in a strong and reliable way without breaking functionality of referenced 3rd party libraries.
img
Full Language Support
.NET Reactor supports all types of managed assemblies (C#, VB.NET, Managed C++, ASP.NET, Delphi.NET, J#...).
img
Intuitive GUI
An intuitive, easy-to-operate GUI provides quick, comfortable operation.
img
Command Line Support
All features support command line invocation, and event driven invocation by Visual Studio Build Events. .NET Reactor produces the finished product in the same way you do.
img
Fairly priced
.NET Reactor is priced to make ownership affordable.
img
Trust
