EnCodeIt

seandisanti · June 16, 2006

Hi I'm having a problem. I have used this on 2 different scripts and it was fast and seemed to work correctly.
I have a new script that is 5kb.
EncodeIt took 43 minutes to obfuscate it and the filesize went from 5kb to 178kb and gets an error of improperly defined function.
the script doesn't have any of the commands listed on page one of this post.
the script unobfuscated works perfectly.

if you're not able to identify where the issue is, it will be hard to help you with a work around. if you feel like sending the source of your script to Smoke_N or I (haha smoke i volunteered you) we can try to isoloate the issue and help with a fix or work around. Neither of us would release your source without your permission.

Just to let you know it gave me more errors than I could count: 59 is when I decided to stop counting.

My script is 4863 lines of code and about 259kb in size. I read about the first 5 pages of this and none of that applies to what is in my script. Anywho love the idea just doesnt work for me. And I have so much code written I just do not feal sifting through it after printing pages of it to try and find and correct the incompatabilities in my script and your obfuscation method.

On a side note it has workd on all my small scripts Love it.

Can't help you solve your issue without a script.... sorry, but glad it works on others.

Yes I know you cant thats understandable was just letting you know it didnt work on yet another but I decided to spend just a tad bit of time looking at where it is having errors and trying to figure out why it is.

I have figured out some of them its called the Function "iniwrite" it screws up on every single one of those so far. It comes up with this for every instance of iniwrite ERROR: $FEA76BD341F960FE: undeclared global variable.

offcourse the obfuscation variable is different for each.

Ill tell you what esle as I get more time to spend on fixing the simple little issues as I get more free time to do so. As I would like to use it on my script.

Anywho I love it and the idea behind it.

BTW just out of curiosity havnt yet tried it on any of my other scripts can you run this multiple times on the same script to add more and more obfuscation?

I would like to see the plain code for this, it works too good for me to believe, I just have to see the code!

Hey SmOke

I searched all the pages but could'nt find an answer to this

I am working on an include file....

can a user include my obfuscatd file in their script

example

MY-File.au3

my obfuscated code

users script

#include<MY-File.au3>

msgbox(0,"Hello World", "My name is User")
; this script in not obfuscated

thanks

The problem your going to run into is it changes the Function names and if your using Global Const variables, it changes those to, and you have to know those to call them, if you do, then it's fine as long as it isn't itself dependent on the other script.

No, the text encoding would get confused.

Dynamic behaviour... You have to go through "steps" to obfuscate or else your all over the place... and when Eval("a" & "b") = $ab how do I split up the $ab = $alkdfu0f92309uafpoie0a9su into Eval("a" & "l" & "k" & "d" & "f" & "u" & "0" & "f" & "9" & "2" & "3" & "0" & "9" & "u" & "u" & "a" & "f" & "p" & "o" & "i" & "e" & "0" & "a" & "9" & "s" & "u") properly (Just one example, I know if you look at the functions closer you'd understand out of most people). Now, I've past the point already of Encoding something ('text') or whatever, then I'd have to back track and do it all over again for these specific functions, and to be honest, It takes long enough as is.
If someone has written a UDF for things like this, and would like them to be included in EnCodeIt then by all means, but you'll find that it just isn't going to work on some of them at all.

You could do these things by doing a standrad one-way hash function, however, people who use the above menitioned functions would pose themselves a security risk as people who decompile the source code can print out the name of the variable/function before it gets through the hash function.

Just something I noticed.

How about the simple addition of 2 directives for EncodeIt:

#randomline-start
#randomline-end

For example, this:

#randomline-start
$a[0] = 999
$a[1] = 234
$a[2] = 461
$a[3] = 714
$a[4] = 822
$a[5] = 2345
$a[6] = 136
#randomline-endoÝ÷ Ù·¢g¬¶¬¡»â¢ë%Êß¹¸¬q«^u»¶èrW«¢+ØÀÌØílÙtôÄÌØ(ÀÌØílÑtôàÈÈ(ÀÌØílÉtôÐØÄ(ÀÌØílÁtôäää(ÀÌØílÍtôÜÄÐ(ÀÌØílÕtôÈÌÐÔ(ÀÌØílÅtôÈÌÐ

What do you think?

Smoke any guess as to why this doesn't work?

Have you tried to just run it ?

_StringEncrypt() is a standard UDF in string.au3.

so you need a statement :#include<String.au3>

Thanks Jdeb, that does look like a standard #include error that you get when you didn't #include the .au3 that the function uses.

WTS · July 3, 2006

this is cool, i think with this and wouters script that modifies the exe it would be nearly impossible to get the source without a lotta bit of trouble..

hey smoken how did come up with this?

When this was released, there was a virtual panic every day almost of people complaining it was too easy to get the source from an AutoIt compiled .exe. So I looked into what would work since AutoIt has to have the script in tact to be able to read it, and obfuscation was the only thing that made sense. Edited July 3, 2006 by SmOke_N

I gave him the idea.....

I used to post snippets of code i was struggling on & requesting help with.

No one could understand what the hell my code was supposed to be doing..

So Smoke took my method of coding, and scripted it! That's all

Im a tourettes coder!!

Try naming the Functions a little different than 1 / 2 at the end... see if that helps, maybe a bit more unique. It looks like it is naming them the same to me (the ones with parameters and the ones without).
