title: Howto implement SFTP with Qt/QNetworkAccessManager (C++)
body: <p>I'm new to Qt and I would like to implement FTP and SFTP support for my software.
  As I googled I discovered that there doesn't exist a sftp library for Qt but it should be possible with QNetworkAccessManager. 
  I tried then to discover on how to build a custom protocol or something like that but didn't figure out how to do it.</p>
  
  <p>Does someone know how I could do that?</p>
  
  <p>Thanks,
  Michael</p>
