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

$sshHostname = "sftp.example.com"
$sshPort = 22

# Connect to an SSH server and establish the SSH tunnel:
$success = $tunnel.SshOpenTunnel($sshHostname,$sshPort)
if ($success -ne $true) {
    $($tunnel.LastErrorText)
    exit
}

# Authenticate with the SSH server via a login/password
# or with a public key.
# This example demonstrates SSH password authentication.
$success = $tunnel.SshAuthenticatePw("mySshLogin","mySshPassword")
if ($success -ne $true) {
    $($tunnel.LastErrorText)
    exit
}

#  OK, the SSH tunnel is setup.  Now open a channel within the tunnel.
#  (Any number of channels may be created from the same SSH tunnel.
#  Multiple channels may coexist at the same time.)

# This example connects to a REST server through the SSH tunnel.
# It will connect to the Amazon AWS service for this example.

    $($tunnel.LastErrorText)

# Use the connection.  (This connection is a TLS running on an SSH channel through an SSH tunnel.
# In other words, TLS is wrapped within the SSH tunnel.)
