Fugu
‘is a graphical frontend for the text-based Secure File Transfer Protocol (SFTP) client that ships with Mac OS X. SFTP is similar to FTP, but the entire session is encrypted, meaning nothing, including passwords, is sent in the clear. Fugu provides a friendly, intuitive interface for OpenSSH's SFTP client, featuring secure drag-and-drop file transfers, remote file editing and remote file preview. Fugu allows you to take advantage of SFTP's strong encryption without having to sacrifice ease of use.
