It’s a little easier to do in a terminal session, so I’ll show you that way too. If you have a hosting account that lets you access a Unix home directory for your account for file transfer, you should be able to set up SFTP with a private key without logging in via a terminal or command-line session at all. Nothing can be intercepted or extracted from your communications, and you can’t be fooled into revealing the key because you never enter it anywhere like you would a password. Making this relatively minor change improves your account security immensely: to log in to your server, someone would need to obtain a private key stored only on your computer. SFTP is often used with a password, but it can be set up to work with a pair of stored encryption keys. SSH replaced the Telnet remote login service (also unencrypted like FTP) with a more sophisticated, encrypted approach. SFTP is not actually a secure evolution of FTP but is instead part of the SSH (Secure Shell) remote access service. (If your Web host provides it, however, consider using it!) Transmit reveals how many different kinds of file transfer protocols exist, including both open and proprietary ones.įor many of us, SFTP (Secure FTP) turned out to be the best solution for secure file transfer.
But it’s funky to set up and also often requires direct Web server configuration access. At one point, WebDAV plus HTTPS seemed like a solution: a WebDAV-enabled Web server allows file transfer and can offer the equivalent of FTP and HTTPS as a solution. There’s FTP over SSL/TLS, which uses a digital certificate of the same type that secures Web sites-but which is hard to configure unless you run a server and can work through the configuration details at a low level.
Later standards addressed this limitation by adding encryption, although insecure FTP remains in widespread use. Designed in the net’s earliest days, FTP never concerned itself with security. One of the oldest still-working protocols on the Internet is FTP (File Transfer Protocol).
