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

    let ssh = CkoSsh()!

    // To get the authentication methods offered by an SSH server, we first connect.
    var success: Bool = ssh.connect("example.com", port: 22)
    if success != true {
        print("\(ssh.lastErrorText!)")
        return
    }

    // Next, we call GetAuthMethods to receive a comma separated list of authentication methods
    var authMethods: String? = ssh.getAuthMethods()
    if ssh.lastMethodSuccess != true {
        print("\(ssh.lastErrorText!)")
        return
    }

    // For example: publickey,password,keyboard-interactive
    print("Authentication methods suported by this serve: \(authMethods!)")

    // IMPORTANT:
    // Getting the authentication methods will intentionally disconnect from the server.
    // We'll need to re-connect, etc. to continue..

    // For example..
    var success: Bool = ssh.connect("example.com", port: 22)
    if success != true {
        print("\(ssh.lastErrorText!)")
        return
    }

    success = ssh.authenticatePw("myLogin", password: "myPassword")
    if success != true {
        print("\(ssh.lastErrorText!)")
        return
    }

    print("SSH Authentication successful.")

    // ...

    ssh.disconnect()
