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.
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.
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.
Assembly Linker Interface
When packaging, during the assembly obfuscation, you can combine assemblies using the assembly linker. For example, instead of deploying main.dll, a.dll, and b.dll separately, you could deploy main.dll using the Assembly Linker interface that is a significant part of Skater .NET Obfuscator. The a.dll and b.dll will be joined into the main.dll
When distributing several closely related but separate DLLs is not that much of a plague, it would be a nice if, since they are so closely interlaced, you could merge these different assemblies into one. The ability to merge multiple libraries together would simplify deployment in many cases; applications that use several different languages or huge applications written in the same language but built upon many different projects would benefit from single-assembly deployment.
The Skater's special Linker interface is the utility that can link multiple modules into a single file for deployment. It does the linkage afterwards your main assembly has been obfuscated. The Linker interface intended for linking multiple managed executables or assemblies into a single module or assembly. The assigned referenced and non-referenced assemblies will be linked into your final obfuscated assembly afterwards when obfuscation is done for your current open assembly. NOTE: The linked assemblies will not be obfuscated. Please obfuscate the joined modules before Linkage. Or you may suggest secure the combined libraries after Linkage.
Usually, if all the functionality of your distributed application is not required at once, you might want to consider having the application divided into separate modules or libraries. The .NET runtime will load each component only when a type is referenced.
On the second hand, packaging everything into a single file will bring performance improvements, mostly because the loader does not have to take the time to resolve all the dependency issues. Also, you do not have to worry about missing dlls when your application is deployed.
