Obfuscar is an open source MIT-licensed obfuscation tool for .NET assemblies that renames metadata to minimal names, making decompiled code hard to read while shrinking executable size. It runs as a dotnet global tool or NuGet package and is configured via an XML file, with a v3 beta offering a modern IL pipeline.
Use cases
- obfuscate .NET assemblies to protect intellectual property
- prevent decompilation of C# binaries with ILSpy
- shrink .NET executable size by renaming metadata
- protect secrets embedded in a .NET assembly
- integrate obfuscation into a CI/CD build pipeline
- obfuscate Unity or Xamarin.Android assemblies
When to choose
- you need a free, open source alternative to commercial .NET obfuscators
- you want basic name-renaming obfuscation for .NET Framework or modern .NET assemblies
- you want a simple dotnet tool that fits into build scripts
When to avoid
- you need advanced obfuscation like control-flow encryption or string encryption
- you will feed it untrusted or malicious assemblies, since its PE-reading APIs are not hardened against such input
- you rely on relative paths or environment-variable expansion in configuration (removed in v3)
