Secure copy protocol (SCP) is a means of securely transferring computer files between a local host and a remote host or between two remote hosts. It is based on the Secure Shell (SSH) protocol. [1] "SCP" commonly refers to both the Secure Copy Protocol and the program itself. [2]
Its main function is secure file transfer between a local computer and a remote server. [6] Beyond this, WinSCP offers basic file manager and file synchronization functionality. For secure transfers, it uses the Secure Shell protocol (SSH) and supports the SCP protocol in addition to SFTP. [7] Development of WinSCP started around March 2000 and ...
PuTTY user manual (copy from 2022) PuTTY (/ ˈ p ʌ t i /) [4] is a free and open-source terminal emulator, serial console and network file transfer application. It supports several network protocols, including SCP, SSH, Telnet, rlogin, and raw socket connection.
SFTP attempts to be more platform-independent than SCP; with SCP, for instance, the expansion of wildcards specified by the client is up to the server, whereas SFTP's design avoids this problem. While SCP is most frequently implemented on Unix platforms, SFTP servers are commonly available on most platforms. In SFTP, the file transfer can be ...
The SSH client and key agent are enabled and available by default, and the SSH server is an optional Feature-on-Demand. [ 21 ] In October 2019 protection for private keys at rest in RAM against speculation and memory side-channel attacks were added in OpenSSH 8.1.
An SSH server is a software program which uses the Secure Shell protocol to accept connections from remote computers. SFTP / SCP file transfers and remote terminal connections are popular use cases for an SSH server.
The advantage of FISH is that all it requires on the server-side is an SSH or RSH implementation, Unix shell, and a set of standard Unix utilities (like ls, cat or dd—unlike other methods of remote access to files via a remote shell, scp for example, which requires scp on the server side).
sftp is a command-line interface client program to transfer files using the SSH File Transfer Protocol (SFTP), which runs inside the encrypted Secure Shell connection. It provides an interactive interface similar to that of traditional command-line FTP clients. One common implementation of sftp is part of the OpenSSH project. [1]
