Protect ASP .NET Source code

[Ganesh Muthuvelu]

Hi,
I have a ASP .NET application that we give to our clients
for them to deploy it in their web server and use it. My
concern is that all of my ASPX pages source code is open
and our clients can open the ASPX file and see the code in
it.

I want to protect my code something like a Windows
application where we give only the .EXE and the dll's. Is
there a way to do the same for ASP .NET applications
also?..

Can anyone guide me with useful likns, tools etc.,?

Thanks,
Ganesh

This is why ASP.NET has the code behind model, which you should use. This
means all code is in .vb file, that gets compiled to a DLL when you compile
your project. You then deploy just the .aspx files (which have UI only) and
the dll, which has the compiled version of your code.

Ganesh,

On top of using the code behind page as Marina recommends, you can also use
the .Net Obfuscator on the generated .dll; then, even if, someone were to
open the .dll with the Ildasm.exe (Which allows you to examine the code in
the .dll) the friendly object names in your .dll files will be replaced with
difficult to read names. This makes it much more complex for anyone to
reverse engineer your .dlls.

.... Of course, if anyone can get into the file system on your web server to
look at the files contained therein, you have a serious security problem
already that has nothing whatsoever to do with ASP.Net.

Precompile yor ASP.Net webapp and then obfuscate it using a tool like Crypto Obfuscator
