title: Difference between .cert vs .cacert (X.509)
body: <p>I have received three files from my hosting company who bought the X.509 certificate for me.</p>
  
  <p><code>.key</code> file - thats the private key<br>
  <code>.cert</code> file - ?<br>
  <code>.cacert</code> file - ?</p>
  
  <p>Whats the difference between the two?</p>
