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".
