If I use N/A as the password, this means that regardless of what password is entered, EXE2AHK will not decompile?

If I use /NoDecompile and a password, how difficult is it for someone to obtain my source code?

What additional steps should I take to protect my source? I'm not looking to block someone who feels like reading the computer memory, but at least everyone else.

Thanks :)

I don't know of any way to stop a determined and skilled person from discovering the true nature of your script (or any program for that matter) -- including any trade secrets it contains.

The best you can do with the default installation of AutoHotkey is to choose a long password and use the /NoDecompile switch.

There may be some other tips on the German forum ( http://de.autohotkey.com/forum/ ) or elsewhere about how to use a compressor other than UPX to compress the script, which may add an additional level of security. Also, I seem to remember seeing something on the German forum about a program that modifies a compiled script to make it even harder to crack.

Could post the links on alternative packer and also how to modifies a compiled script to made it harder to crack please?

Coz the latest autohotkey version compiled script can already be decompiled! :(

Dbof from the german forum has modified an exe and it works! :wink:
So we must wait :(
I´m german, sorry for my bad english,
currently there is no script safe!
Every ahk exe can be decompiled through a simple drag & drop action with a program, that can be downloaded for free and legal on the web :)
Greets and good luck,
DHMH

Update from Chris: As of 4/29/2009, I know of no software that can automatically decompile a password-protected, compiled script that uses /NoDecompile. There was one program that claimed to be able to do so; but testing shows that it does not work with the most recent releases of AutoHotkey.
