How to: SSH Keys in Ubuntu
The Secure Shell (SSH) allows you to create secure connections to remote hosts and destination servers. SSH is typically used if you need to access a remote Web host, and you need a secure connection to change settings on that computer. Unlike Telnet or traditional file transfer protocol (FTP), SSH is fully encrypted so you can be assured of the connection status.
