Best Free Obfuscator for .Net code

Question

I was looking for a free Obfuscator tool for .NET 2.0 & 3.5.

I have checked out DotFuscator Community Edition. But that is limited to renaming. Does anyone knows of a similar tool with better obfuscation features on offer??

I tried to download the Aspose Obfuscator but the link is directing to Aspose Product Categories page, where the Obfuscator is not listed.

Hi Yasser, I have just checked out XHEO's CodeVeil webpage. I must say the feature list if impressive. However, it might take sometime now, before I have the chance to download & test CodeVeil.

It was not true on that moment (03/21/2009). The Skater .NET obfuscator Light Edition (freeware version) is always offering a lot of free code protection features that are free of charge. Try the freeware obfuscator: http://www.rustemsoft.com/freeware_obfuscator.htm

Answer 17

Hey Rahul,

I am using FxProtect Express. It is also free .net obfuscator. You can try it.

FxProtect Express - Free .Net Obfuscator 

Answer 18

I agree with LogicNP about Crypto Obfuscator. I tried it and it is better than free because of its speed and ease of setup compared to DotFuscator.

I tried Skater and it was very slow with my WPF project. I paid $300 for the professional version Crypto Obfuscator. Lots of nice features ... like encryption of string constants, and breaks Red Gate .Net Reflector on IL decompile. I figure I'll recoup the investment over a couple of years in time saved alone.

Answer 21

Try Agile.net obfuscator @secureteam.net , basic obfuscation features included with the community edition are quite extensive and would answers most of your needs if all you're interested is obfuscating your software.

Their paid version includes additional features including code encryption and code virtualization which are more advanced code protection techniques, in case you're developing a non-commercial software you can ask them for a FREE license for their commercial version.

Answer 22

Dotfuskator - good obfuskator. It already has a great reputation.
I've heard that ArmDot is good, this is a fairly new tool for code obfuscation.

Answer 23

I also tried this obfuscator, it looks promising
