title: JSch SFTP security with session.setConfig("StrictHostKeyChecking", "no");
body: <p>I use JSch with private key to FTP file </p>
  
  <ol>
  <li>jsch.addIdentity(privatekeyfile);</li>
  <li>Session session = jsch.getSession( "user", "domain.com" ,22);    </li>
  <li>session.setConfig("StrictHostKeyChecking", "no");</li>
  </ol>
  
  <p>Line 3 is in question. Without this line, JSch does not work.</p>
  
  <p>My question is:
  Will line 3 make SFTP transfer insecure?</p>
