SFTP Client

What is the SFTP Client

SFTP Client is software that uses the SFTP protocol to transfer files safely to and from a remote computer. Although it serves the same purpose of transferring and managing files, under the SFTP Client hood it is very different from FTP. Many of these differences stem from the fact that SFTP is above the SSH (Secure Shell) protocol.

What about SCP and FISH?

If you are looking for file transfer protocols, you might find SCP (Secure Copy) and FISH (File Transfered Over Shell Protocol). These two protocols are similar to SFTP because they use SSH to facilitate connections (FISH can also use rsh).

One major difference is the use of ports.Unlike using two discrete ports, SFTP Client, only uses one. By default, this port is TCP port 22 (default SSH port). Using SSH ports has the added benefit of making SFTP generally more "firewall friendly" and less likely to be blocked by default.

In addition, the SFTP Client allows users to benefit from using SSH keys. If you are not familiar with the benefits of SSH keys and asymmetric cryptography, see this article from Digital Ocean. In short, the SSH key adds an additional layer of security to the authentication process.
SCP is a popular solution that proves useful if you only need to transfer files. However, if you need to list remote directories, create new directories, delete files, or do other administrative tasks, you must use SFTP Client.FISH is not used much like SCP or SFTP, but it might help when resources and the ability to install software on the server side are very limited.

What to look for in SFTP client
The answer to this question is really "dependent". If you are a home user or only manage one or two WordPress sites, you might be able to get away with a very simple file transfer client. All you need is a simple graphical user interface (GUI) and support for one or two protocols. On the other hand, if you are an advanced user or are subject to certain compliance requirements, you may have a broader list of needs when it comes to the SFTP Client Download software requirements
