The FTP plugin also supports the SSH File Transfer Protocol, or SFTP. SFTP is much more secure than FTP because it encrypts all network traffic. However not all FTP servers support SFTP. SFTP support requires Java 1.4.
To connect to an SFTP server, either select Connect to Secure FTP Server from the file system browser's Plugins menu, or use the Open from Secure FTP Server and Save to Secure FTP Server commands in the Plugins>FTP menu.
SFTP support is provided using the sshtools library.
