(free?) Delphi obfuscator

For Win32

Are there any free obfuscators for Delphi Win32?

A program that makes reverse-engineering harder, works on executables.

Why would you want an obfuscator for an executable?

So you are using Delphi for .NET then I presume.
I never thought of that.

There is not much chance of anyone thinking it is worthwhile to try and untangle any win32 compiled code executable.

No it's pure Win32, not .NET.

Have you used an application like PE EXplorer? With it, I can see many things from my application, like the names of the procedures and functions, the style of all the available forms and even more!

An obfuscator names the functions so that they don't give away what they do, consideR:

Instead of Button1Click, you'd get AdjajJDFjaa.

Yes. But that is all you get.
(I believe) you will get neither the code inside the function nor the parameters to the function.

If you think knowing the names of the functions is much use then....

Obfuscators are used with INTERPRETED code; because you can get at that code relatively easily.

the problem with getting at the delphi function names is quite serious the way i see it, there is a good obfuscator, the name is Pythia be sure to use version 1.1 of it since 1.0 has some bugs, also, check the program output for any menu captions that get scrambled, specially, pop-up menus that are not always available for disply, those sometimes get caught in the obfuscation, a very easy way to fix it is to recaption it when you enable the visibility of it.

Good luck with your programs.

there aren't too many good PE encryptors around... and most are buggy and not suitable for real world usage.
if you're willing to shell out some bucks, then take a look at ASProtect, Themida, VMProtect.
these won't hold against a professional reverser though. since all of them have been cracked.
Another method is to use ICElicense or Securecode from ionworx but i don't know if these are supported any more.
