_StringEncrypt is returning ""

Many ways. PM one, create a bug ticket (Bug Trac up the top...)

Try this, which uses a different RC4 encryption function, that is acutally more "standard" than the one AutoIt's String.au3 UDF uses (that function is by SkinnyWhiteGuy):

expandcollapse popup

$sString = "This is a text string."
$sKey = "This is my key phrase."
$sCrypt = rc4($sKey, $sString) ; encrypted binary
ConsoleWrite("Debug: $sCrypt = " & $sCrypt & @LF)
$sString = rc4($sKey, $sCrypt) ; decrypted binary
ConsoleWrite("Debug: $sString = " & $sString & @LF)
$sString = BinaryToString($sString) ; plain string
ConsoleWrite("Debug: $sString = " & $sString & @LF)
$bh = StringToBinary($sString) ; plain binary
ConsoleWrite("Debug: $bh = " & $bh & @LF)
$reString = rc4($sKey, $bh) ; encrypted binary
ConsoleWrite("Debug: $reString = " & $reString & @LF)
$reString = rc4($sKey, $reString) ; decrypted binary
ConsoleWrite("Debug: $reString = " & $reString & @LF)
$reString = BinaryToString($reString) ; plain string
ConsoleWrite("Debug: $reString = " & $reString & @LF)

; On success returns encrypted/decrypted version of $value
; Author:  SkinnyWhiteGuy on the AutoIt forums at www.autoitscript.com/forum
; Notes:  The same function encrypts and decrypts $value.

        $c = BitXOR(Dec(StringTrimLeft(BinaryMid($value, $i, 1), 2)), $S[$j])
        $output = Binary($output) & Binary('0x' & Hex($c, 2))
    Next
    Return $output
EndFunc   ;==>rc4

All the talk of UTF encoding your strings made me think of another topic. A true binary function won't care if you hand it ASCII/ANSI/UTF-8/UTF-16/Binary/etc.

Edit: Put missing first line back in demo.

Thats because its the string you want to encrypt:

$sString = "Jesus i'm tired of seeing this thread"

[Innovative]

This works. But i really wish to solve my _StringEncrypt problem.. Someone please help me ! There will be alot of inconvenice without _StringEncrypt function

I prefer this function over StringEncrypt() for this reason: This RC4() function from SkinnyWhiteGuy() returns/reads data that can be directly interchanged with a "standard" RC4 encryption in another program, or another language. AutoIt's native StringEncrypt() does not. I would like to see it included in some one of the UDF's as perhaps _BinaryRC4() or some-such, giving AutoIt an INTEROPERABLE encryption.

P.S. SkinnyWhiteGuy also posted DES and AES functions.

nice lengthy thread

Useless to pm.. They will only get irritated instead

Cannot remember getting irritated at you but I do prefer not to get tons of PMs about script issues .... but I hadn't read this one yet till Bert PMed me, been busy with other things.

Now to the issue at hand. I have no clue why things go wrong at this point.

Lets start with: Open the String.au3 located in Autoit3\includes and copy/paste the _StringEncrypt function into your testscrip.au3 and remove the #include string.au3. try again to see if it fails.

When it still fails then attach the testscript.au3 a post allowing us to download it and to see what the file encoding is?

Settle down there lad. People in different parts of the world sleep at different times to you. They will get back, when and if they have something for you but that definitlt will not be when they are sleeping. On the other hand Jos dreams in AutoIt.

Look at the (MY) time you posted in your quoted replies ... I am living in the Netherlands in the GMT+1 timezone and at my age you need the sleep Edited February 2, 2008 by Jos

[PsaltyDS]

Listen... If you want help you need to work with me because I am not going to search for things when its easy for you to do it.

@Jos: He did do what you asked earlier at my request, and the results were posted (sort of). I don't like getting the results back as an annoying screen shot vice simple copy/paste from the console, though.

That all seems to isolate the problem down to a part of the encrypt portion (in that function the decrypt is only throwing an error because of the null fed back to it from the failed encrypt).

CrazeStar1074 then said something about having trouble with english, and Sheville and Bert started looking at language/keyboard settings and maybe some UTF weirdness. That lead me to recommend a binary encryption (by SkinnyWhiteGuy) vice the string method in _StringEncrypt(). The binary encryption works fine, but he doesn't want to use it (go figure).

I would still like to know what the issue is, just for my own sense of closure. But if his problem (which no one else has duplicated) is related to language/UTF stuff then it's gone over my head. Maybe the results of those two posts linked above could help.

Good point (the first point, I won't comment on the later...)

He didn't do what I asked since there is no original scriptfile attached ... and I don't think I asked for much but am getting annoyed when people respond like that when you are trying to help.

I guess he gets what he already assumed before ...

Could you please upload the results of following into a text file so we are able to compare.

Basically, before the script starts, before you press run, clear the console, then run the scripts. Copy the output. It will be long.

Thank you,

Heres the result..

Thanks,

Are you sure that is the full results? Because I am not seeing you actually getting into Loop_A3.

Otherwise everything is as should.

How is it possible for loop_A3 not to be done?

You're missing around 50 lines in comparision. You are not even starting loop_a3. It just ends? Otherwise every single line that you are running, every number, every varible is correct. Your missing this bit here:

Something I missed as well...

The reason why Loop_A3 never exists, is because of Loop G. It never returns a value for you. It should be:

>> Loop G>> 1/8
>> Loop G>> Var = $i_EncryptCountH>>1
>> Loop G>> Var = $v_EncryptModified>>¾
>> Loop G>> 2/8
>> Loop G>> Var = $i_EncryptCountH>>2
>> Loop G>> Var = $v_EncryptModified>>¾«
>> Loop G>> 3/8
>> Loop G>> Var = $i_EncryptCountH>>3
>> Loop G>> Var = $v_EncryptModified>>¾«»
>> Loop G>> 4/8
>> Loop G>> Var = $i_EncryptCountH>>4
>> Loop G>> Var = $v_EncryptModified>>¾«»»
>> Loop G>> 5/8
>> Loop G>> Var = $v_EncryptModified>>¾«»»Ï
>> Loop G>> 6/8
>> Loop G>> Var = $i_EncryptCountH>>2
>> Loop G>> Var = $v_EncryptModified>>¾«»»Ï¢
>> Loop G>> 7/8
>> Loop G>> Var = $i_EncryptCountH>>3
>> Loop G>> Var = $v_EncryptModified>>¾«»»Ï¢É
>> Loop G>> 8/8
>> Loop G>> Var = $i_EncryptCountH>>4
>> Loop G>> Var = $v_EncryptModified>>¾«»»Ï¢ÉÎ
>> Var = >>¾«»»Ï¢ÉÎ

$v_EncryptModified = $v_EncryptModified & Chr(BitXOR(Asc(StringMid($s_EncryptText, $i_EncryptCountG, 1)), Asc(StringMid($s_EncryptPassword, $i_EncryptCountH, 1)), 255))

And look where we end up again. Back to this line all over again.

Let me work on another example to see what's happening...
