stop other stealing .net files, encryption?

[confused1234]

Hi'

I'm about currently working for someone building them a .net web app.

I'm about to launch it onto his servers.

There is another .net developer working on something else.

I have no interest in his worl but he has shown an interest in my work, because i think he's worried about his job security and is tryin to push me out.

He has full ftp access and will no doubtly try and copy my code.
There are chunks of code on there (most of it) that is the same as other projects i have made and would not be good for other people to have.

My question is how can i fix this?
Can i stop him accessing the individual .aspx files? OR
Can i run a script to jumble the code to make it unreadable i.e remove white space and change variable names to something else?
What is the standard way of doing this?
What would you do?
p.s changing his ftp access is not an option.

I'm really worried , please help me out.

Thanks

Develope your web application on a private computer and PUBLISH the pre-compiled website to the real server.
that way if he has access to the real server, he will not get any of the backend files.
Then you just have to worry about keeping him out of the private computer.

thanks, i was unaware of PUBLISH, but i found that you can decompile this easily wihtout any problems.

i found Spices.Obfuscator that encripts the output but it costs money. does anyone know a free/open source method to secure your work?

Thanks

I want to say microsoft has one that can be attached to visual studio. Not sure if it's free or not.

I would not say "decompiling" it is easy per say, but it is doable. I mean all it does is compile all your code into a DLL, so you're at the same risks as you would a "compiled" windows application.

do you Obfuscate your work?

[Plater]

Nope. I don't do anything really "mission critical" that I would worry about what people find when stealing.

thanks so much for your help plater.

does anyone else obfscate? which progs do you use? does it make it a complete pain to update?
