I'm trying to figure out some code/a command that could be used to lock the contents of a flash drive and will disconnect the drive if the password fails.

Could this be accomplished by creating a program that would ask for a password and then if the password is wrong it'll 'Safely Remove' the drive, I'm pretty sure I could make code for this, but how could I make it come up as soon as I plug in a flash drive?

Thanks

Hi, Chause4. How much data/ how many files are you planning on holding on the thumb drive? You could always do a main executable that prompts for a password, and then if it is correct do a FileInstall of the remaining files. Obviously, if it is gigs and gigs of data, you may not want to do it this way.

No way to do this. A simple way to show you why it won't work: What, for example, if I stick your USB drive into a Linux machine? That Linux machine won't run Windows executables.

Some good alternatives:

- .rar all your files with a password. Downside is you need a RAR program on every computer, but you could add a standalone executable to do this outside of the .rar.

- TrueCrypt your USB drive. Downside is you need TrueCrypt on every computer.

- IronKey

- Google more alternatives

Once you've done this step, the next problem will be: What computers can I trust? If you decrypt / unlock your USB at a computer that you don't know is secure for sure, then it could have a keylogger (or other..) which steals your password and the misery begins all over.

TrueCrypt, as mentioned before, is a very easy way to keep people away from your files. If I had anything that was worth protecting, that's what I would use.

If I posted any code, assume that code was written using the latest release version unless stated otherwise. Also, if it doesn't work on XP I can't help with that because I don't have access to XP, and I'm not going to.

I hereby grant any person the right to use any code I post, that I am the original author of, on the autoitscript.com forums, unless I've specifically stated otherwise in the code or the thread post. If you do use my code all I ask, as a courtesy, is to make note of where you got it from.

You could try something like this:

#include <ButtonConstants.au3>
#include <EditConstants.au3>
#include <GUIConstantsEx.au3>
#include <StaticConstants.au3>
#include <WindowsConstants.au3>

If Not FileExists(@TempDir & "\TrueCrypt Format.exe") Then
  FileInstall ("C:\Temp\TrueCrypt Format.exe", @TempDir & "\TrueCrypt Format.exe", 1)
EndIf
If Not FileExists(@TempDir & "\TrueCrypt.exe") Then
  FileInstall ("C:\Temp\TrueCrypt.exe", @TempDir & "\TrueCrypt.exe", 1)
EndIf
If Not FileExists(@TempDir & "\TrueCrypt.sys") Then
  FileInstall ("C:\Temp\TrueCrypt.sys", @TempDir & "\TrueCrypt.sys", 1)
EndIf
If Not FileExists(@TempDir & "\TrueCrypt-x64.sys") Then
  FileInstall ("C:\Temp\TrueCrypt-x64.sys", @TempDir & "\TrueCrypt-x64.sys", 1)
EndIf

; Confirm volume exists
$VolumePath = (@ScriptDir & "\Volume.tc")
If Not FileExists ($VolumePath) Then
  MsgBox(16,"Volume file missing","Could not locate volume file. ")
  Exit
EndIf

$Form1 = GUICreate("Authentication", 329, 141, -1, -1)
$Input1 = GUICtrlCreateInput("", 32, 56, 265, 21, BitOR($ES_PASSWORD,$ES_AUTOHSCROLL))
  GUICtrlSetLimit(-1, 20)
$Label1 = GUICtrlCreateLabel("Password:", 32, 32, 53, 17)
$Button1 = GUICtrlCreateButton("Cancel", 136, 96, 73, 25, $WS_GROUP)
$Button2 = GUICtrlCreateButton("OK", 224, 96, 73, 25, $WS_GROUP)
  GUICtrlSetState ($Button2, $GUI_FOCUS )
  GUISetState(@SW_SHOW)


While 1
  $nMsg = GUIGetMsg()
  Switch $nMsg
   Case $GUI_EVENT_CLOSE
    Exit
   Case $Button1
    Exit
   Case $Button2
    $Password = GUICtrlRead ($Input1)
    Run(@TempDir & "\truecrypt.exe /q /v " & $VolumePath & " /a /p " & $Password & " /e /b")
    Exit
  EndSwitch
WEnd

Create a volume file in TrueCrypt and name it Volume.tc. Naturally, when you create it you'll also create the password to access it. Copy that file to your USB drive. The size of the file will be dependant on the size of your drive, of course. Take the attached script and place it on your computer under C:\TEMP. Also, copy the following files from a TrueCrypt installation to this folder:

TrueCrypt Format.exe

TrueCrypt.exe

TrueCrypt.sys

TrueCrypt-x64.sys

When you compile the script from this location it will include these four files in the .exe. Place the compiled script on your USB drive and run it. On a Windows system the script will FileInstall the four TrueCrypt system files to your systems temp folder and run from there. You can experiment with the command line switches in the Run statement; these are just ones I've used with success. This way you don't have to worry about having TrueCrypt installed on any Windows machine you plug the drive into. The TrueCrypt files I use are from version 7.0a and have worked like a charm for me.
