Secure Data Transfer

Secure Data Transfer is a file transfer protocol, supported by various clients such as OpenSSH, that encrypts information allowing it to be transmitted securely from point to point across a wired or wireless network. FTP alone is not a secure method since the information is transported in plain text allowing login ID's, passwords and sensitive information to be intercepted and read by unauthorized persons who may be illegally monitoring your electronic communications.

Currently, almost all communications in computer networks are done without encryption. As a consequence, anyone who has access to any machine connected to the network can listen in on any communication. This is being done by hackers, curious administrators, employers, criminals, industrial spies, and governments."

SFTP is an interactive file transfer program, similar to ftp, which performs all operations over an encrypted ssh transport. It may also use many features of ssh, such as public key authentication and compression. SFTP connects and logs into the specified host, then enters an interactive command mode. The second usage format will retrieve files automatically if a non-interactive authentication method is used; otherwise it will do so after successful interactive authentication." - OpenSSH.org
