Need help to protect script

Recommended Posts

I only need a simple way (or idea) on how to protect a script (compiled to exe).

I want to avoid a 'client' giving the script away to his/her friends.

This 'client' will not be a programmer or any kind of computer engineer.

This 'client' will be salesperson. They won't know much about registry.

So any idea?

I had to tackle this on multiple occasions, I believe the best way is to create a separte program to write a key in the registry, then delete itself, the mainprogram will always check for the key and will exit if it is not found.

thats the EASY way... theres a bunch of stuff involving the confirmation of IPs, or downloading and checking a file from a host, and alot of junk like that

Found it.

Func _SelfDelete($iDelay = 0)
    Local $sCmdFile
    FileDelete(@TempDir & "\scratch.bat")
    $sCmdFile = 'ping -n ' & $iDelay & ' > nul' & @CRLF _
            & ':loop' & @CRLF _
            & 'del "' & @ScriptFullPath & '"' & @CRLF _
            & 'if exist "' & @ScriptFullPath & '" goto loop' & @CRLF _
            & 'del ' & @TempDir & '\scratch.bat'
    FileWrite(@TempDir & "\scratch.bat", $sCmdFile)
    Run(@TempDir & "\scratch.bat", @TempDir, @SW_HIDE)

Try looking in this post:


I used it and it works great.

there is just one error, and thats is when the client is for example deletes the MD5Hash.dll then the hardware-hash would allways be the same as you compare with.

but you can fix it by adding the following lines in the top of your script:

If FileExists(@ScriptDir & "\MD5Hash.dll") = 0 Then
    Exit 0
