Using SSH

SSH (Secure Shell) is a protocol for encrypting and securing various kinds of data transfers over a network or the Internet. SSH works by opening a secure channel between the SSH server and an authenticated user's computer, through which many kinds of data may be sent or retrieved.

SSH can be understood as a large pipe: its purpose is to carry whatever is passed through it from one place to another without letting anything leak in or out.

The WS_FTP SSH Server uses SFTP (SSH File Transfer Protocol) over SSH2 to transfer files.
