how can i set password on my compiled exe?

when the user will open it then it should ask for a password but if the user will give wrong password for three times then the program will exit.

can someone assist me?

Just whipped this up. If you are only worried about checking the password when compiled, look at the @compiled macro.

$correctPassword = False
For $i = 0 To 2
$password = InputBox("Password", "What is the password?", "xxxx", "*")
If $password == "My Secret Password" Then 
    $correctPassword = True
    ExitLoop
Else
    MsgBox(0,"","Wrong Password")
EndIf
Next

If Not $correctPassword Then Exit

MsgBox(0,"","Your entered the correct password, so your program is running")

It's gonna be more work, but if you want to store the password in the script then I recommend creating a hash of the pwd and storing that. That means of course you'll have to implement a hash mechanism of some sort, but there are plenty of examples on this forum.

thanks for your efforts but the customer want to use multiple passwords or any better way of protection like generating new keys for each user.

i hope some of you will give the same support as both of you gave me.

i dont know anything about hash mechanism because i am new to coding...

If users launch this from a network or have access to a common folder on the network, you could store individual user keys in a config (INI) file and authenticate it. Of course you would need to encrypt the key before writing to config and decrypt while running the application to challenge casual hackers.

Here's an example of using a hash to store an encypted password using mrRevoked's Hashing using mahine code and the example above from Prab.

#include <md5.au3>

$pass = "0x78C5D6797011323278C9D593AB0A37D7" ; <-- = "This is my password!"

$correctPassword = False
For $i = 0 To 2
$password = InputBox("Password", "What is the password?", "xxxx", "*")
If _MD5($password) = $pass Then
    $correctPassword = True
    ExitLoop
Else
    MsgBox(0,"","Wrong Password")
EndIf
Next

If Not $correctPassword Then Exit

MsgBox(0,"","Your entered the correct password, so your program is running")

Expanding spudw2k's suggestion to include (mine) for a config file on a shared drive:

#include <md5.au3>

$IniFile = @WorkingDir & "\config.Ini"
If NOT FileExists($IniFile) Then $IniFile = @ScriptDir & "\config.Ini"
If NOT FileExists($IniFile) Then 
   MsgBox(4096, "Problem", "Could NOT Find Application's Configuration File !")
   Exit
EndIf

$UserPwd = IniRead($IniFile, @UserName, "PWD", "")
If StringLen($UserPwd) < 1 Then
   MsgBox(4096, "Problem", "You are NOT authorized to use this Application" & @CRLF & "Contact Application's Administrator to Authorize you")
   Exit
EndIf

$UserPwd = _MD5($UserPwd)

Local $I, $Response
For $I = 0 to 2
      $Response = InputBox("Password", "Enter Application Password", "", "*")
      If StringLen($Response) < 1 Then Exit
      If $Response = $UserPwd Then ExitLoop
Next;$I
If $Response <> $UserPwd Then Exit

; The rest of your Application Code...

You would create a separate App. to generate and Store Passwords for every User and store it on a shared drive

#include <md5.au3>
$IniFile = @WorkingDir & "\config.Ini"; Or Make it Interactive so you can select the INI File name/location
$UserID = "JoeUser"; Again an example, make it an input box
$UserPwd = "JoesPassword"; Give Joe this unhashed Password
IniWrite($IniFile, $UserID, "PWD", _MD5($UserPwd))

thanks to all of you who helped me but this is not what i am trying to achieve.

i want a protection something like KeyGen's. my program will create new user name and password for each user. and the password will only work if it is used on correct pc which have same userName and on other computers this u/password should not work at all.

i will create a KeyGen which will create new keys for each user. anyone can help me? any ideas? any links? any code? any example?

You can implement a check against the computer for unique info. i.e. Hostname, HD Serial, MacAddress, etc.

_MD5($password & @ComputerName & DriveGetSerial("C:"))

no, i want to create a KeyGen for it but i have no idea about it.

how can i get HDD serial? (Not Drive Serial)

I thought DriveGetSerial did that. The DriveGetSerial for c: is not he same as the volume serial (at least on my pc) Edited by spudw2k

You might also want to check out http://www.autoitscript.com/forum/index.ph...mp;#entry570458. It doesn't have the stuff about locking a login to a computer(you could add that), but it works well enough for a home application.

Gotta love that UDF... :) >_< :idiot:

LOL anyway. You could easily restrict it to a single computer by changing:

_StringEncrypt(1, $loginPS, $loginUN & $EncryptionPassword & $loginPS, $EncryptionLevel)oÝ÷ Ù:ºÚ"µÍÔÝ[Ñ[Ü
K   ÌÍÛÙÚ[Ë   ÌÍÛÙÚ[S    [È ÌÍÑ[Ü[ÛÜÝÛÜ    [È ÌÍÛÙÚ[È   [ÈÙ[YK    ÌÍÑ[Ü[Û][
oÝ÷ ØêÚ*¶¢YhÂ)àrwjëh×6@OSType
@OSVersion
@ProcessorArch
@ComputerName

This IMO is the best way to secure a file because even if the hacker decompiles the EXE he still needs your password you entered to decrypt it.

;               $iAlgID - hash algorithm identifier, can be one of the following:
;                  0x8001 = MD2
;                  0x8002 = MD4
;                  0x8003 = MD5 (default)

thanks for it. this is what i was looking for.

Just because I'm lost on this one...

1) How do you leave the generating function out of the script? You have 2? Or do you use another language to compile it?

2) How is there security in AutoIt it all?

I've asked/searched this for quite a while and it came down to this:

ALL AutoIt scripts can be decompiled (Thus getting how a password is generated)

ALL scripts can be de-obfuscated.

Thanks for explaining it to me :) I'm to stupid to figure out how using HASH instead of some other encrypting algorithm is more secure >_<

1) Just pull the generating function out... You could still figure it out rather easily from the source if you decompiled.

2) You are correct... As far as I have seen as well, the only security offered is security by obscurity, which is not very effective.

And yes, ALL autoit scripts CAN be decompiled, and de-obfuscated. This will only keep honest people honest... anybody that goes looking for a way to break it, will indeed.

The script I posted was simply an example of what the OP was looking for. I posted simply to get some greater minds thinking on the right track and creating a better method hopefully... but still, since all autoit scripts can be decompiled, I don't know how to make it truly secure.

EDIT: Forgot to answer this one:

Well... it isn't. This was just a way to have a unique "password" for a unique username. I was trying to go off of the CD-Key idea the OP was trying to accomplish, where there would be multiple possibilities of acceptable usernames and passwords. Edited by danwilli
