This article will demonstrate how to establish a secure connection and upload a file using the SFTP (FTP over SSH) protocol and the components provided in SSH Factory for .NET.
Note: This example demonstrates using SFTP (FTP over SSH). If you are wanting to use the FTPS (FTP over SSL) protocol then please see the article Secure FTP using C# and FTPS (FTP over SSL).
