Many thanks

My Input:

MsgBox(0, "", "lol""lol")
Global Enum Step -2 $e1var1, $e1var2 = 13, $e1var3

What I get:

global $A0D00103156=A5C00001342($Os[0x1]),$A2900202B1E=A5C00001342($Os[0x2]),$A4D00303A03=A5C00001342($Os[0x3]),$A5B00604555=A5C00001342($Os[0x4])
MsgBox(Number($A0D00103156), "", $A2900202B1E)
Global Enum Step -Number($A4D00303A03) $A3C00400532, $A0D00506036 = Number($A5B00604555), $A5400703D09

With .au3.tbl being the following:

203020[BAA43t6C6F6C22226C6F6C[BAA43t203220[BAA43t20313320[BAA43t

Which is equal to:

0 
lol""lol
 2 
 13

Note:

1. Numbers have a leading and trailing space

2. The string still has the double quote escaped (two times) although it won't get processed

3. The enum's stepvalue got replaced which is erroneous and should have already been fixed according to the changelog

Is it normal like this or am I doing something wrong?

I used the newest version available (1.0.29) by clicking it twice and selecting my file..

How did you get to the "Which is equal to:" results as the posted script doesn't produce that?

When I run this line in both original and obfuscated versions it produces the same result without any extra spaces:

MsgBox(0, "", "lol""lol")
MsgBox(0, "", "!" & 1 & "!")

[PieceOfIce]

out of the .tbl-file, just used some javascript to convert it back to ascii

e.g. the first entry is "203020" which is " 0 ", strangely padded with spaces

there is only one zero in the script means it's from "MsgBox(0,..." but there actually weren't any spaces therefore I wonder why it's padded, additionally they aren't of any need there, so they just waste some bytes ("203020" vs "30")..

When I run this line in both original and obfuscated versions it produces the same result without any extra spaces:

I don't quite understand..

I did it like this:

1. I saved my script which is like I wrote above in some .au3-file

2. I downloaded your obfuscator.zip

3. I executed it and selected my .au3-file

4. I compiled the outcoming Sample_Obfuscated.au3 with Aut2Exe

And when executing Sample_Obfuscated.exe I receive the following MessageBox:

---------------------------

---------------------------
lol""lol

(instead of >lol"lol<)

and afterwards this error:

---------------------------
AutoIt Error
---------------------------
Line 5  (File "C:\AutoIt\Sources\Obfuscator Test\Sample_Obfuscated.exe"):


Error: Badly formated Enum statement

Try using the latest available Beta version of Obfuscator v 1.0.29.3 which contains a fix for the double quote issue.

Hi Jos,

thanks again for this great tool, can't say it often enough .

But of course this is not the only reason why I post ...

I'm obfuscating my tool SMF with the following switches: "/sf /sv /om /cs=0 /cn=0". I do this to speed up the overall script execution (just done a replace of all $ and had some 48.000 hits in my script). Looking at the obfuscated script itself I've noticed the following:

Variables always start with an "a" and have at least 3 characters => $aXX

Functions are always at least 4 characters long, underscore "_" being the first and the last one => _XX_

Would it be possible to implement an iteration through all valid characters for variables and functions? This would shorten up my script by a good and measurable amount. E.g. when $az is reached start over with $b1?

I did an iteration once myself. I've found no restrictions to rename a var to anything of the 37 elements long array, and the restrictions I've found for functions could be avoided with something like this ("pseudocode"):

Global $_BCaddlNums[37] = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, "_", "a", "b", "c", "d", "e", "f", "g", "h", "i", "j", "k", "l", "m", "n", "o", "p", "q", "r", "s", "t", "u", "v", "w", "x", "y", "z"]

Dim $aFuncs_Skip[24]=["do", "in","if","or","to","abs","and","asc","chr","cos","dec","dim","exp","for","hex","int","log","mod","not","opt","ptr","run","sin","tan"]

$sFuncsNew = _BasetoBase($i + $var_offset, 10, 37)

If Asc(StringLeft($sFuncsNew,1)) < 58 Or _StringInArray($sFuncsNew, $aFuncs_Skip) Then ; numbers are no good as first letter for functions

ContinueLoop

EndIf

Would be great if you could take a look into this how hard it would be to further optimize the /om switch ...

Best Regards

i'm using Yashied's HotKey 2.0b function which i really like, but i'm having problems when obfuscating my script (switches don't seem to matter)...

-### StripOnly/StripFunc Error: Found Call() statement using unsolvable Func, which will/could lead to removal of Funcs that are used by the Call() statement.
>### current Func: HK_WM_HOTKEY

ok, fine, so then i add...

#Obfuscator_Ignore_Funcs=HK_WM_HOTKEY

and i get the same warning as above, which, from what i've read here, is to be expected apparently, but my script is still broken (the hot-keys i set with _HotKey_Assign() don't work)

i also tried adding "_HotKey_Assign" and "_GUICtrlHKI_GetHotKey" as well as my entire function from which the hot-keys are set (a configuration UI) and the results are the same in that the hot-keys never work

all works fine without obfuscating, but i'd like to chop the output size ( i usually use /sf /sv /om /cs=0 /cn=0)

this is with Obfuscator 1.0.29.0 and i tried both with and without the /beta switch

[BrewManNH]

You could make a dummy call to that function at the start of the script. Just add HK_WM_HOTKEY() somewhere in the script and you won't have to worry about it being stripped. As long as this function returns immediately and you're not affecting anything by calling it randomly in the script, it should get rid of the issue.

[iCode]

i don't understand why #Obfuscator_Ignore_Funcs=HK_WM_HOTKEY is not working though

the only "Call()'s" are in the "HK_WM_HOTKEY" func

[KaFu]

The problem is not where it's called, but what it calls... it calls $hkTb[$lParam][1], which is set in the function _HotKey_Assign() to $hkTb[$Index][1] = $sFunction... which is exactly the string I've already mentioned in the HotKey UDF post... e.g.:

_HotKey_Assign(BitOR($CK_CONTROL, $VK_ESCAPE), 'Quit') => #Obfuscator_Ignore_Funcs=Quit

[iCode]

ok, now i got it working properly. i was ignoring the wrong funcs. thanks again KaFu

btw, i moved this here because i realized this an obfuscator issue and not a HotKey issue

[KaFu]

Good to hear ...

Is there really so much gained by also changing the Func names?

Variables I can imagine the gain can be substantial having seen your project and I can have a look at that.

Variables I can imagine the gain can be substantial having seen your project and I can have a look at that.

Just did an obfuscation of my latest dev version ("/sf /sv /om /cs=0 /cn=0") and found 1.074 functions in the obfuscator.log to be replaced. It's quite hard to count all occurrences, but I assume them to be at least some 10.000. So the number is lower than for variables (not really surprising ), on the other hand vars in /om have a minimum length of 3, funcs of 4, so more potential there . Like you mentioned the total gain in size reduction and speed improvement is relative to the overall size of the project. Glad you took the request ... Edited December 2, 2011 by KaFu

[Jos]

Have a go with the current Beta v1.0.29.4 It will create shorter Var and Func names and sequences them individually.

v1.0.29.4:
- Fixed issues with relative includes using .. in the filename.
- Changed the /OM variable length

Nice , that reduced SMF's obfuscated source from 1.370 to 1.306KB (~5%). I'll test it and let you know if I find any bugs... Thanks a lot for taking this request Jos!

Best Regards

[guinness]

Same as well, I've seen a nice 5% decrease in filesize. Thanks Jos.

[Melba23]

Jos,

Same 5% decrease here and no problems encountered so far.

Dank je wel.

could be, but i really need a script to replicate this unless you are telling me it always crashes.
