Protecting my source code

Recommended Posts

sublimnl

Hi guys. I am getting ready to release a program that I have been working on in AutoIt and I believe that in the past you have been able to decompile an AU3 exe back to its source code, or that the source code was embedded within the exe. I think I read that this is not the case anymore and just want to make double sure that there is nothing special I need to do to protect my code from being extracted from a compiled exe.

Thanks!

sublimnl,

Searching the forums will provide you with a lot more information in greater detail, but in brief:

- Your plain language script is within the compiled .exe, but in compressed form. It is not immediately viewable with a hex editor, but is by no means secure as it is expanded in memory when the .exe is run.

- Obfuscator (part of the full SciTE4AutoIt3 package) will obscure your script by changing variable and constant names (and a lot more!), which makes it harder to decompile but again does not render the .exe secure.

So, compiling an AutoIt script will prevent quick snooping, but a determined, experienced hacker can relatively easily get your source - including passwords, specific filenames, etc - or the encryption routines you have used in your script to encrypt/decrypt them if they are stored in another file.

Probably not what you wanted to hear.... :D

thanks for that. yes, not what I wanted to hear, but after looking at the obfuscated source code, I think that will be enough for me. :D

Obsucator doesnt help much as what it does can be reversed easily.

This is how it is for now.Use encryption if you store passwords or

sensitive data in your script.

you can probably try armadillo on your exe after to encrypt it
