| + | The SSH File Transfer Protocol (SFTP) is a network protocol that provides file access, file transfer, and file management functionalities over secure connection.((Technically %%SFTP%% can operate over any reliable data stream, not necessarily a secure one. Though in a significant majority of uses, it operated over a secure SSH protocol. WinSCP in particular does not allow any other use.)) It was designed by the Internet Engineering Task Force (IETF) as an extension of the Secure Shell protocol (%%SSH%%) version 2.0 to provide secure file transfer capability.((&wikipedia_ref(SSH_File_Transfer_Protocol|SSH File Transfer Protocol))) | ||
| + | |||
| + | In its basic functionality the %%SFTP%% is similar to an old [[ftp|FTP]], while having better designed advanced functionality. Unfortunately not all SFTP server implementations take advantage of the advanced features, yet. | ||
| + | |||
| + | Especially in its later versions (from 4 upwards), the %%SFTP%% protocol is more platform independent, compared to both [[ftp|FTP]] and [[scp|SCP]]. | ||
| + | |||
| + | Unlike SCP, for connection with an %%SFTP%% server you do not need access to shell (although some implementations may still require that). | ||
