Demonstrates how to authenticate with a username + .ppk PuTTY private key w/ SSH Tunnel. Visual FoxPro

LOCAL lnSuccess

*  This example assumes the Chilkat API to have been previously unlocked.
*  See Global Unlock Sample for sample code.

loTunnel = CreateObject('Chilkat.SshTunnel')

*  Load a .ppk PuTTY private key.
loPuttyKey = CreateObject('Chilkat.SshKey')
lcPpkText = loPuttyKey.LoadText("qa_data/ppk/putty_private_secret.ppk")

*  The ppkText contains this content:
