Fugu SSH is a Mac OS X graphical frontend to
OpenSSH's Secure File Transfer application (SFTP).
SFTP is similar to FTP, but, unlike FTP, the
entire session is encrypted, meaning no passwords
are sent in cleartext form, and it is thus much
less vulnerable to third-party interception. Fugu
allows you to take advantage of SFTP's security
without having to sacrifice the ease of use found
in a GUI. Fugu also includes support for SCP files
transfers, and the ability to create secure
tunnels through SSH.
