(.NET Core C#) REST through SSH Tunnel

Demonstrates how to connect through an SSH Tunnel (via port-forwarding) to make REST API calls.

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

Chilkat.Socket tunnel = new Chilkat.Socket();

string sshHostname = "sftp.example.com";
int sshPort = 22;

// Connect to an SSH server and establish the SSH tunnel:
bool success = tunnel.SshOpenTunnel(sshHostname,sshPort);
if (success != true) {
    Debug.WriteLine(tunnel.LastErrorText);
    return;
}

// 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 != true) {
    Debug.WriteLine(tunnel.LastErrorText);
    return;
}

//  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.

bool bTls = true;
int port = 443;
int maxWaitMs = 5000;

// This returns a socket object that is a single channel within the SSH tunnel.
channel = tunnel.SshOpenChannel("s3.amazonaws.com",port,bTls,maxWaitMs);
if (tunnel.LastMethodSuccess != true) {
    Debug.WriteLine(tunnel.LastErrorText);
    return;
}

// 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.)
success = rest.UseConnection(channel,true);
if (success != true) {
    Debug.WriteLine(rest.LastErrorText);

    return;
}

// Provide AWS credentials for the REST call.
