    //  Important: It is helpful to send the contents of the
    //  sftp.LastErrorText property when requesting support.

    let sftp = CkoSFtp()

    //  Any string automatically begins a fully-functional 30-day trial.

    //  To use a SOCKS4 or SOCKS5 proxy, simply set the following
    //  properties prior to connecting:
    //  The SOCKS hostname may be a domain name or
    //  IP address:
    sftp.SocksHostname = "www.mysocksproxyserver.com"
    sftp.SocksPort = 1080
    sftp.SocksUsername = "myProxyLogin"
    sftp.SocksPassword = "myProxyPassword"

    //  Set the SOCKS version to 4 or 5 based on the version
    //  of the SOCKS proxy server:
    sftp.SocksVersion = 5

    //  Note: SOCKS4 servers only support usernames without passwords.
    //  SOCKS5 servers support full login/password authentication.

    //  Connect to the SSH server.
    //  The standard SSH port = 22
    //  The hostname may be a hostname or IP address.
    var port: Int
    var hostname: String?
    hostname = "www.my-ssh-server.com"
    port = 22
    success = sftp.Connect(hostname, port: port)
    if success != true {
        print("\(sftp.LastErrorText)")

    }

    //  Your application is now connected to an SFTP/SSH server
    //  through a SOCKS4 or SOCKS5 proxy.
    //  ...
