RustemSoft proposes Skater .NET Obfuscator, an obfuscation tool for .NET code protection. It implements all known software protection techniques and obfuscation algorithms.
If you would like periodically obfuscate your .NET products the Skater .NET Obfuscator is for you. RustemSoft is using the Skater for internal needs securing all RustemSoft .NET executables and assemblies. Its command-line version running in batch mode is much useful for your scheduled products updates. You have to assign settings for an assembly in GUI version first. Then the batch obfuscate task will use the settings.

Main features of Skater .NET Obfuscator

Prohibits reverse engineering
Obfuscated application usually is not recompilable
Processes any .NET application, executable or assembly
Encrypts string constants
Compatible with any .NET framework (1.0, 1.1, 2.0, 3.0, and 3.5)
Control flow obfuscation stops decompilers and deobfuscators
Scrambles class names, method names, field names etc.

Skater has been a very reliable and easy to use program. It has all of the features I need without the problems of other obfuscators. I've tried others but after obfuscating, my program immediately crashes. Even with minimal obfuscation settings. Trying to get in touch with the the creators of these programs takes days or longer. In between that time, I found Skater and never looked back. Skater has always been able to obfuscate my software with all settings turned on. RustemSoft stands behind their product as well - giving very good immediate responses, which is rare in general. It's a pleasure doing business with them.

It works great! I love the Visual Studio 2005 integration. I have a lot of constants and strings in my projects. I obfuscated them all then tried to view them using Lutz Roeder's .NET Reflector version 4.2.51.0 and I could not read them at all. It works great and for the price it's a no brainer to use this great product.
This product is more efficient than Microsoft's refactoring power toy, and is very easy to use!

You need to obfuscate your .NET code because IL (.NET Intermediate Language) code contains all of the information, apart from comments, that is in .NET executable (*.exe or *.dll) files. Using a decompiler a belligerent competitor can easily reverse engineer your .NET apps. To resist this threat, it is possible to obfuscate your assemblies before distributing your software.
The obfuscation process bereaves all unnecessary information used by debuggers from your .NET classes. Also, class, interface, field and method identifiers are renamed to make them meaningless.
By using Skater .NET Obfuscator the obfuscation cannot be reversed.
Skater .NET Obfuscator has dual representation as a GUI interface and as a command-line tool as well. Skater .NET Obfuscator is designed to be seamlessly integrated into your build process that is why it has the command-line interface. This is done in the reliable and repeatable fashion when the obfuscation tool depends on a graphical user interface for operation.

Application vulnerabilities, Intellectual Property theft and revenue loss are among the most serious risks facing companies today. According to Business Software Alliance statistics, four out of every ten software programs is pirated in software business, world wide.

Unauthorized access to source code can offer a quick back entrance into your systems, business processes and revenue streams. Global piracy rate has increased 40% over the past years and nearly $11 billion is lost. This is definitely a clear threat for software producers and thus to global economy. With more than half of million developers with some level of access to .NET reengineering tools providing near instant access to source from any .NET binary, organizations across industries are entrusting on obfuscation to managing these risks. Over the years, several software protection techniques have been developed, code obfuscation is one of them and it is very promising.

Code obfuscation is a form of software protection against unauthorized reverse-engineering.
The chief functions of any software protection technique can be determined as detection of pirate attempts to decipher or tamper software, protection against such attempts and alteration of software to ensure that it functionality degrades in an undetectable manner if the protection fails.

Cardinal obfuscation techniques:

Private and Public members names obfuscation.
It scrambles names of classes, methods, variables, and other assembly members. It makes assembly code reverse engineering much harder by obfuscating names. Some Skater settings allow to generated names that will prevent recompilation.

String encryption.
The string encryption function allows you to select literal values of string data type to be encrypted. You may select all strings to be encrypted. Also you may mark some specific strings to obfuscate. You have choice to apply a cryptography method for the string encryption. Only specified strings will be encrypted /obfuscated.

Control Flow obfuscation intended to stop decompilers and deobfuscators from functioning correctly.
Control Flow obfuscation subdues reverse engineering by scrambling .NET methods (functions and procedures) code. The Control Flow obfuscation algorithm distorts and reorders the IL code in the assembly, inserting bait branch instructions while preserving code semantics. This obfuscating essentially converts assembly method implementations into "spaghetti code", making interpretation by human hackers and decompiler tools much more difficult.
Actually Control Flow obfuscation involves the insertion of additional instructions. Applying of this feature increases the size of the output assembly. If a maximum level of code protection is not required for your assembly, you may want to consider disabling this feature to minimize your output executable code size.
