What is the difference between FTP and SFTP?

Answer 1

When we send any data with the help of FTP over the internet , it usually transmit in plain text ....it means no encrption & anybody can easily read it ..

But in SFTP , all the data encrypt & then transmit...

Ftp works on port number 20 & 21 where 20 use for data & 21 use for control while SFTP works on port number 115.

There are actually three SFTP protocols.

1. Serial File Transfer Protocol, a protocol used to transfer files between a PC and an embedded device using RS-232 or similar serial protocols. This protocol doesn't use a tcp/ip stack.

2. Simple File Transfer Protocol, an unsecured and rarely-used file transfer protocol from the early days of the Internet. This protocol uses tcp port 115.

3. Secure File Transfer Program, a network protocol designed to provide secure file transfer and manipulation facilities over SSH. This protocol uses tcp port 22 and is the more common meaning when using "SFTP".

Answer 2

FTP (File Transfer Protocol) is a standard network protocol used to transfer files between a client and a server over a network. SFTP (Secure File Transfer Protocol) is a secure version of FTP that uses encryption to ensure data confidentiality and integrity during file transfers. SFTP provides a more secure way to transfer files compared to traditional FTP.
