Hi All,

kindly give me the solution or sourcecode to protect the dll without using third party software.

Thanks and Regards,

You can use the obfuscator that's built into ASP.NET 1.x and above, or you could use one of these 3rd party obfuscators which generally claim to be better:

Discussion forums are intended as problem-solving aides and to assist in troubleshooting.

I just thought I would share with a collection of points which I shared as an article over here in the ways to best harness the benefits of discussion forums:

Another obfuscator which gives good protection to your .net assemblies is Crypto Obfuscator (http://www.ssware.com/cryptoobfuscator/obfuscator-net.htm)

using Obfuscator alone is not going to help. You need to understand what obfuscator work and then code accordingly so that it would become hard for someone to decompile your code.

Few months back I read an excellent article which went into much details .. the link to the article is lost my unorganized bookmarks ..

I am sorry my comment isn't that helpful .. but I just wanted to let you know .. its more than just using software to obfuscate your code.

Try CliSecure, a .NET obfuscator and code protection tool by SecureTeam. You may find it here: http://www.secureteam.net

It's only 299$ for the express edition, it might worth your time and effort developing your own solution.
