What stops them just editing this, as well as whatever else they plan on changing after recompiling your application?

I mean, say your App is HWID protected. So I make some edits, and remove the HWID. Now, thanks to this function, that cracked App won't run. Well done. However, if I am able to remove the HWID Function, there is no reason I can't do the same to this function.

What do you mean vordal?
This functions are created to use in other programs the md5 changes when somebody trys to hex edit your program and then the program will not be useable.

He means whats stopping them from editing:

PHP Code


<?php 
if MD5Hash = MyMD5Hash then
End if 


to

PHP Code


<?php 
if MD5Hash = MD5Hash then
End if 


Anyways, good tutorial, this could be useful.

He means whats stopping them from editing:

Writing your own simple encryption algorithm and encrypting the details, seeing how you should already be doing that for the clients hwid number anyways...

But it's not a binder protector. If we bind the file with another it will run.

Yes, thanks for the idea. :]

That's what I was thinking about. Then add HWID protection, login protection & imagination.

how about doing it like this ;)

Code

Public Sub Md5Check()
  Dim md5 As String
    md5 = "Already calculated Md5 of your app"' < Calculated MD5 of your app :) ( NO INTERNET CONNETION :) )
  End Try

  If Not md5 = Md5Get() Then
   Me.Close
  End If
    End Sub

Even worse, just hex the MD5.

Thinking about doing this. The way I was doing a HWID lock with my programs as it connects to my website, looks for their PC name in a folder, if it doesn't find it shuts down. If it does find it, it looks for the HWID in the file, then it checks their combination that they received when they purchased the program. This will help though, thanks :)!
