CSharp Obfuscator

CSharp Obfuscator protects your .NET application code through obfuscation transforms, while maintaining debugging abilities for quality assurance testing. It can be seamlessly integrated with the existing development cycle.

Renaming

The extension allows you obfuscate all declarations within the selected scope. All related references will also be updated. It will help you to separate declarations, which can be obfuscated, from those that should not be obfuscated. The extension also streamlines the integration of the obfuscation and build automation. Check out the standalone CSharp Obfuscator tool for more details.

Scrambling Strings

The extension extracts all strings and puts them in a separate source file. All strings are serialized and encoded. For further protection, you can encrypt the strings with an extension DLL file.

Before

After

String file

Encrypt strings with an extension DLL

• Download the extension project
• Implement the encryption in the EncodeStringArray method
• Return the full name of the decryption method that exists in your project/solution
• Build the project and put the output file(csoextension.dll) in the root folder of your solution

Mapping File

The mapping of the original declaration and the obfuscated declaration is stored in the file (cso.db).

The main differences between the extension version and the standalone version

• The extension version can only do the obfuscation file by file. The standalone version can do it for all files within the same solution.

• The extension version can only use ASCII characters to do the obfuscation. But the standalone version supports ASCII characters and symbol characters.

• The extension version cannot obfuscate declarations that are defined in a XAML file or update references that are used in a XAML file.

• The extension version cannot define the obfuscation rules that specify which declarations should not be obfuscated.
