If I have this code to use the FTP protocol to upload a file:

                ' URI
                lcURI = "ftp://" + cHost + lcPort + "/" + lcDrive + cRemoteDirectory + "/" + cRemoteFile

                ' FTP setup
                loFtpWebRequest = System.Net.FtpWebRequest.Create(New Uri(lcURI))
                loFtpWebRequest.Credentials = New System.Net.NetworkCredential(cUsername, cPassword)
                loFtpWebRequest.KeepAlive = False
                loFtpWebRequest.Method = System.Net.WebRequestMethods.Ftp.UploadFile
                loFtpWebRequest.UseBinary = True
                loFtpWebRequest.ContentLength = lnFileLength

What kind of adjustements will be required to support an FTP server access which would use a certificate?
