It is a GUI-based or command-line-based software program, which provides the capability to connect to the SFTP server and have the SSH incorporated within it. Operating systems like Windows, Linux systems, Mac OSX, and other systems are there which support this protocol and we can run SFTP services on these OS. When the SFTP server software is installed on the system it will generate the SSH key for the host from which the user can create and grant credentials and permissions to the other users and groups to access the system for data transfer.

SFTP ServerĪs said earlier, the secure file transfer protocol works on the client-server architecture thus for using SFTP, one should have both the client program and server software.įor setting up the SFTP server connection, the user should have the Internet supporting web server and SFTP port number 22 directed towards the secure file transfer protocol server setup which is installed on the system. Also with SFTP, the data transfer will take place along with the mainstream connection thus it need not provide a separate connection likewise in FTP for file transfer. It is a packet-based protocol thus it works much faster than the simple file transfer protocol. SSH-2 version is incorporated into the SFTP which provisions a complete encrypted and secured transport layer onto which one can run the SFTP commands and exchange data also. The secure file transfer protocol generally runs on the TCP port number 22 but we can assign any port as per the availability to run this protocol. The data connection over which the transmission is done should be protected with authentication policies and passwords which should be known only to the sending and receiving end.

It is a network layer protocol that provisions the secure file access, management, and secure exchange of data between two users or in client-server architecture over a secure network or reliable network connection. It is known by different names such as SSH File Transfer Protocol or Secure File Transfer Protocol and Secret File Transfer Protocol.
