Hi all,
I am new in programming and I just joined a company that offers secure file transfer software components. So I firstly want to gather some selective information on why should I use Secure FTP instead of FTP? And why is SFTP better than FTP?
Thanks in advance!

Hi, first of all congratulation for job. Despite the similarity in name the two protocols are completely different. In FTP all data is passed back and forth between the client and server without the use of encryption. This makes it possible for an eavesdropper to listen in and retrieve your confidential information including login details. With SFTP (http://www.jscape.com/secureftpserver/) all the data is encrypted before it is sentient across the network. Hope you will satisfy with my opinions. I wish you for your great career.
All the best!

The differents between SFTP and FTP, SFTP is only encrypting files during file transfer. So that is all :).

that's right..

just like you get http and shttp were shttp is secure and encrypted.

SFTP is an encrypted/secure FTP connection

Ofcourse, there has to be a trade-off :) SFTP is for those who are very much security consious and uploads critical files via internet.

Please check this out:

You will note that TLS ftp security can be used just to encrypt login data and there are no tradeoffs regarding speed during data transfers (upload or download).

You will notice those tradeoffs if you use SCP with SSH2 where every packet is encrypted.

SFTP is a network protocol that allows you to transfer files and do things like change the permissions of a remote file. Secure File Transfer Protocol. A secure version of FTP which do not transfer sensitive data in human digestable format. It is functionally similar to FTP, but because it uses a different protocol, you can't use a standard FTP client to talk to an SFTP server, nor can you connect to an FTP server with a client that supports only SFTP.

FTP and SFTP are like HTTP and HTTPS, both transmit data in a secure manner across network so when a hacker tried to snoop all they'll get is garbage. Its some what secure, but FTPs itself are not all that secure.

SFTP, or secure FTP, is a program that uses SSH to transfer files. Unlike standard FTP, it encrypts both commands and data, preventing passwords and sensitive information from being transmitted in the clear over the network. It is functionally similar to FTP, but because it uses a different protocol, you can't use a standard FTP client to talk to an SFTP server, nor can you connect to an FTP server with a client that supports only SFTP.

You can use SFTP with a graphical SFTP client or at the command line..........
