While SMTP is the protocol that provides the secure channel, to transfer or copies the file from one host to other hosts or systems. SFTP establishes the control connection under SSH protocol and it is used in port number 22.

Definition of FTP:

FTP is an application layer protocol. FTP is a mechanism provided by TCP/IP for transferring the file from client to server or same as from the server to the client.  The issues resolved y FTP are, like two systems between whom the file is being exchanged may use different file conversion or different ways to represent text and data or a different directory structure. To resolve this problem FTP has a list of commands.

  • FTP does not provide any secure channel to transfer the file between the hosts whereas the SFTP protocol provides secure channels for transferring the files between the hosts on the network.
  • FTP doesn't provide encryption while SFTP provides encryption for sending the data.
  • FTP makes a connection using a control connection on TCP port 21. While the SFTP transfer the file under the secure connection established by SSH protocol between client and server. SFTP allows incoming collection on port 22.
