title: Qt Code signing cross-platform
body: <p>I'm about to deploy my application written in <code>Qt</code> and now want to sign the code to avoid the <code>Windows 8 smartscreen</code> as well as <code>identified developer</code> on OS X. </p>
  
  <p>My application will be shipped to Mac and Windows.</p>
  
  <p>Is there any cross-platform solution to this? </p>
  
  <p>I've had a look at digicert extened validation (EV) it seems to be very easy to sign a Windows application.</p>
  
  <p>What are my options here? I would like to avoid something to complicated.</p>
