title: Is it possible to modify a file without changing its hash value
body: <p>I need to edit some cfg files for an application, but the thing is the application wont start if I do since it must match. I dont have the sources of the application.</p>
  
  <p>I guess if the hash doesnt match the hash of the exe, it exits.</p>
  
  <p>Could you bypass this somehow?</p>
