System Lockdown

Recommended Posts

welll, here is another boring boring night...

I wrote a "System Lockdown" program. I know there are ways around it but... here..

woops, forgot to get rid of the HotKeySet("{ESC}") line(for debugging) :).. fixed now..

;System Lockdown
if (RegRead("HKEY_LOCAL_MACHINE\Software\SystemLockdown", "") == "") Then
    _CreatePassword()
Else
EndIf
;HotKeySet("{ESC}", "_Close")
#include <guiconstants.au3>
;#include <misc.au3>
$main = GUICreate("System Lockdown", @DesktopWidth, @DesktopHeight, 0, 0, BitOr($WS_POPUP, $WS_CLIPCHILDREN))
GUICtrlCreateLabel("System Lockdown", 350, 10, 500, 500)
GUICtrlSetFont(-1, 24, -1, -1, "Comic Sans MS")
GUICtrlSetColor(-1, 0xFFFFFF)
GUISetBkCOlor(0)
GUISetState()
           $hWnd = GUICreate("System Lockdown", 500, 170, 250, 150, BitOr($WS_POPUP, $WS_BORDER, $WS_THICKFRAME), BitOR($WS_EX_CLIENTEDGE, $WS_EX_STATICEDGE))
GUISwitch($hWnd)
           $AdminPassword = GUICtrlCreateLabel("Admin Password: ", 5, 25)
           $AdminPasswordInput = GUICtrlCreateInput("", 125, 23, 200, -1, $ES_PASSWORD)
           $AdminLogin  = GUICtrlCreateButton("Login!", 400, 140, 90, 30, $BS_FLAT)
           $StatusLabel = GUICtrlCreateLabel("Please type in the Admin password to unlock the system.", 10, 150)
GUISetState()
While 1
    if (WinExists($hWnd)) Then WinSetOnTop($hWnd, "", 1)
    if (WinExists("Windows Task Manager")) Then WinSetState("Windows Task Manager", "", @SW_HIDE)
    if not (WinActive($hWnd)) Then WinActivate($main)
    $msg = GUIGetMsg()
    if ($msg == $AdminLogin) Then
        $Check = Decode(RegRead("HKEY_LOCAL_MACHINE\Software\SystemLockdown", ""))
        if ($Check == GUICtrlRead($AdminPasswordInput)) Then
            WinSetOnTop($hWnd, "", 0)
            GUIDelete($hWnd)
            ;Show User Options
            $hWnd = GUICreate("System Lockdown", 500, 170, 250, 150, BitOr($WS_POPUP, $WS_BORDER, $WS_THICKFRAME), BitOR($WS_EX_CLIENTEDGE, $WS_EX_STATICEDGE))
            GUISwitch($hwnd)
            GUISetState()
            WinSetOnTop($hWnd, "", 1)
            GUICtrlCreateLabel("Welcome to your control panel! Hotkey: ESC to exit.", 150, 5)
            HotKeySet("{ESC}", "_Close")
            $UnlockSystemButton = GUICtrlCreateButton("Unlock System!", 75, 25, 100)
            $ChangePwdButton = GUICtrlCreateButton("Change Password!", 325, 25, 100)
            While 1
                $msg = GUIGetMsg()
                Select
                Case $msg = $UnlockSystemButton
                    Exit
                Case $msg = $ChangePwdButton
                    _CreatePassword()
                EndSelect
            WEnd
            
        Else
            _RecordAttempt()
            GUICtrlSetData($StatusLabel, "Invalid Password!")
            GUICtrlSetColor($StatusLabel, 0xFF0000)
        EndIf
    EndIf
    
WEnd

Func _Close()
    WinSetState("Windows Task Manager", "", @SW_SHOW)
    Exit
EndFunc

Func Decode($string)
    $str = StringSplit($string, "")
    Local $ret_str
    For $i = 1 to $str[0]
        $ret_str &= Chr(Asc($str[$i])-55) 
    Next
    Return $ret_str
EndFunc

Func Encode($string)
    $str = StringSplit($string, "")
    Local $ret_str
    For $i = 1 to $str[0]
        $ret_str &= Chr(Asc($str[$i])+55)
    Next
    Return $ret_str
EndFunc

Func _RecordAttempt($file = "log.txt", $hour = @Hour, $minute = @Min, $second = @SEC)
    $f = FileOpen($file, 1)
    FileWriteLine($f, "Login Attempt >> " & $hour & ":" & $minute & ":" & $second)
    FileCLose($f)
EndFunc

Func _CreatePassword()
    $NewPassword = InputBox("Welcome! First time user", "Please enter a password you would like to lock your computer with:", "", "*")
    RegWrite("HKEY_LOCAL_MACHINE\Software\SystemLockdown", "", "REG_SZ", Encode($NewPassword))
    MsgBox(0, "Thankyou!", "Thankyou, your password was set to: " & $NewPassword & @CRLF & ". Do not forget it!")
EndFunc

Bugs.

if a user is not admin he cannot write to the setting HKEY_LOCAL_MACHINE, so the user is lock out for good.

that happened to me and i had to restart the computer.

so i suggest you use HKEY_Current_user for more user compatibulity. or you can add a check so when user admin it can write to HKEY_LOCAL_MACHINE and at other time to HKEY_Current_user.

Peace
