  Obfuscation…

  Hvorfor Obfuscation? Den koden du skriver for .NET ligger helt åpen for alle å se selv om den er i form av en dll eller exefil. Siden disse filene blir kompilert først i runtime av …….

  Please can you update the list of obfuscators adding Babel Obfuscator?

  Name: Babel
  Company: Alberto Ferrazzoli
  Price: Free

  Address:
  http://code.google.com/p/babelobfuscator/

• timm on September 25th, 2008 at 4:30 pm

  Updated, added Babel.

  I have a .NET application that runs in conjunction with MS XP/Vista and Microsoft PowerPoint. I want to deploy the strongest code protection option available that will be fully compatible with Microsoft Office Applications to help avoid .NET support/compatibility issues, e.g. missing interop assemblies or .NET updates. Considering these and future compatibility issues which is a better solution:

  – Code obfuscation for .NET – stick with .NET and make it more difficult to reverse engineer

  – Code conversion from .NET to native code. Could we deploy to platforms without .NET Framework or support Office for Mac using this approach?

• timm on September 25th, 2009 at 9:07 am

  It comes down to how much you want to pay for your requirements.

  Some obfuscators are real crap. At the very least, the obfuscator should crash .NET Reflector when you attempt to read the protected assembly. CodeWall is a good choice at $399.

  But the best obfuscators will also foil in-memory attacks. CodeVeil and CliSecure are examples, but both cost over $1200/seat.

  If you are concerned about clients having the proper version of .NET installed, then you may want to convert from .NET to native code. XenoCode PostBuild is an example at $1600/seat.

  What a big list is this! Very informative post. Thank you.

• Daniel Dolz on April 6th, 2010 at 9:11 pm

• wowpanda on May 29th, 2010 at 11:22 pm

  hi, can you add Netorbiter to your list?
  http://www.zolohouse.com/wow/NetOrbiter/index.html

  I just finished it, supports .net 1,2,3, 64bit or 32 bit, cross dll obfuscates. WPF/Silverlight supported (some manu work involved).

• GodsDog on September 15th, 2010 at 3:04 pm

  Could you please change the link to the Spices.Net Obfuscator product page to this: http://www.9rays.net/Category/55-spicesnet-obfuscator.aspx ?
  And start price of this product is $399.90 (console edition). That product is free for non-commercial use.
  Thanks in advance

• Mark L on March 11th, 2011 at 10:18 am

  Just over a year ago we discovered that someone had created a keygen for our commercial software. 2 years of work could have gone up the spout, and the dangers of developing software on the .Net platform (e.g how easy assemblies are to reverse engineer) became very clear.
  We looked around at all the different products that were on the market and they were all either far too expensive or really complicated. We just wanted something that we could point at our final compiled versions of our assemblies, hit ‘go’, and then distribute the protected article.
  Skater .Net obfuscator fitted the bill perfectly, and was the best value for money solution that we found (and we looked at a lot of those on offer!).
  So, I would like to thank RustemSoft for producing what is a great bit of software.
  A change of licence keys a year ago, and an extra couple of minutes to scramble the final assemblies before we distribute a new version and the problem of key gens and such has completely gone away.

• william on May 17th, 2011 at 4:40 pm

  Babel is no longer free. The free version only runs for a few days. You must pay to add at least one feature to get past this – not terrible, but it’s no longer free.

• sharc on September 29th, 2011 at 7:49 am

  Orange Heap obfuscator (http://orangeheap.blogspot.com) and CodeFort obfuscator (http://codefort.org) are not mentioned here. They both work very well and look very efficient. Orange Heap is absolutely free and CodeFort hsa different licences including free one.

• G. Himangi on February 15th, 2012 at 12:55 am

  Can you add Crypto Obfuscator to the list? It is a lot cheaper but still has all of the features found in others, as well as some unique ones like Anti-Debug, Anti-Tamper, etc.

  Name : Crypto Obfuscator For .Net
  Link : http://www.ssware.com/cryptoobfuscator/obfuscator-net.htm

• Priyank on February 20th, 2012 at 6:31 am

• Priyank Goel on February 20th, 2012 at 9:18 am

  Can you please add new link for the MAYCOMS FxProtect obfuscator.

  http://www.maycoms.net/fxprotect-obfuscator

  And starting price of this product is $499 (Professional Edition). Express edition of this product is free.

  Thank you…

• Patrick M. on March 2nd, 2012 at 3:37 am

  Thanks for this list!

  Unfortunately, the SharpObfuscator is pretty much dead other than the time it wastes developers by being downloadable. It crashes as soon as one wants to obfuscate even a pure C# DLL from VS2005 (around the time when the code was last updated).

  It should be removed from your list to save others the trouble.

  Thanks again!

• Dan Randolph on April 2nd, 2012 at 12:19 am

  Crypto Obfuscator missing from list.

  I have been using Crypto Obfuscator and am very pleased with the features and performance. I can obfuscate a large WPF project quickly with no problems.

  To obfuscate the same project with Dotfuscator took hours of setup and debugging.

• Paul on October 29th, 2012 at 3:36 pm

  Aspose is discontinued

• Steven on August 23rd, 2014 at 6:45 am

  1. SmartAssembly costs much more than $399 now
  2. SharpObfuscator and Obfuscar seem to be discontinued

• Yves on February 2nd, 2016 at 2:38 pm

  SeeUnsharp .NET Obfuscator is missing in the list. It’s relatively new and under active development. Prices range from 99 to 499 € depending on the set of features. It’s available at http://seeunsharp.net/obfuscator .
