In this article sftp, an alternative to scp will be explained. As said in our SCP’s article, both scp and sftp work through the ssh protocol in contrast to FTPS (MS Windows) encrypted through SSL. The ssh protocol is encrypted and the information traveling from a device to another through it is safe in contrast to protocols like telnet or ftp which are unencrypted allowing sniffers to interfere the data as shown previously when we explained how to sniff images being transferred within an unencrypted network or protocol.
