For example, the following configuration can be used in the ssh-broker-config.xml file:

<profile name="sftexa"
              id="id1"
              host="sftexa.ssh.com"
              port="12345"
              connect-on-startup="no"
              user="sftuser">
       <ciphers>
         <cipher name="crypticore128@ssh.com" />
       </ciphers>
       <macs>
         <mac name="crypticore-mac@ssh.com" />
       </macs>
       <transport-distribution num-transports="4">
       </transport-distribution>
       <authentication-methods>
         <authentication-method name="publickey" />
       </authentication-methods>
       <compression name="none"/>
       <server-banners visible="no" />
</profile>

To enable non-interactive authentication, the private key on the Client is stored with a NULL passphrase. It is important that the key directory and the key file have the correct permissions (for example, 700). For more information, see User Authentication with Public Keys.
