| - | Despite SSH in its name, it is designed to work over any reliable data stream, but WinSCP supports only operation over [[ssh|SSH]], which is also by far its most common usage. | + | 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))) |
| - | Being operated over SSH, it is secure protocol. In its basic functionality it is similar to old [[ftp|FTP]], while having better designed advanced functionality. Unfortunately not all SFTP server implementations take advantage of the advanced features, yet. | + | In its basic functionality the %%SFTP%% is similar to an old [[ftp|FTP]], while having better designed advanced functionality.
