The Secure Shell Protocol (SSH) is a cryptographic network protocol for operating network services securely over an unsecured network. Its most notable applications are remote login and command-line execution.
The File Transfer Protocol (FTP) is a standard communication protocol used for the transfer of computer files from a server to a client on a computer network. FTP is built on a client–server model architecture using separate control and data connections between the client and the server. FTP users may authenticate themselves with a clear-text sign-in protocol, normally in the form of a username and password, but can connect anonymously if the server is configured to allow it. For secure transmission that protects the username and password, and encrypts the content, FTP is often secured with SSL/TLS (FTPS) or replaced with SSH File Transfer Protocol (SFTP).
In computing, the SSH File Transfer Protocol is a network protocol that provides file access, file transfer, and file management over any reliable data stream. 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 capabilities. The IETF Internet Draft states that, even though this protocol is described in the context of the SSH-2 protocol, it could be used in a number of different applications, such as secure file transfer over Transport Layer Security (TLS) and transfer of management information in VPN applications.
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. "SCP" commonly refers to both the Secure Copy Protocol and the program itself.
PuTTY 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. It can also connect to a serial port. The name "PuTTY" has no official meaning.
File eXchange Protocol is a method of data transfer which uses FTP to transfer data from one remote server to another (inter-server) without routing this data through the client's connection. Conventional FTP involves a single server and a single client; all data transmission is done between these two. In the FXP session, a client maintains a standard FTP connection to two servers, and can direct either server to connect to the other to initiate a data transfer. The advantage of using FXP over FTP is evident when a high-bandwidth server demands resources from another high-bandwidth server, but only a low-bandwidth client, such as a network administrator working away from location, has the authority to access the resources on both servers.
SFTP may refer to:
gFTP is a free and open-source multithreaded File Transfer Protocol client program. It is most used on Unix-like systems such as Linux, macOS, and Sony PlayStation 3. It includes both a graphical user interface (GUI), which utilizes the GTK+ graphical toolkit, and a command-line interface. gFTP is released under the terms of the GPL and has been translated into 45 languages.
FTPS is an extension to the commonly used File Transfer Protocol (FTP) that adds support for the Transport Layer Security (TLS) and, formerly, the Secure Sockets Layer cryptographic protocols.
The following tables compare general and technical information for a number of File Transfer Protocol (FTP) clients. Unless otherwise specified in footnotes, comparisons are based on the stable versions without any add-ons, extensions, or external programs.
WinSCP is a free and open-source SSH File Transfer Protocol (SFTP), File Transfer Protocol (FTP), WebDAV, Amazon S3, and secure copy protocol (SCP) client for Microsoft Windows. Its main function is secure file transfer between a local computer and a remote server. 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.
SmartFTP is a network file transfer program for Microsoft Windows that supports file transfer via FTP, FTPS, SFTP, WebDAV, Amazon S3, Google Drive, Microsoft OneDrive, Box, Google Cloud Storage and Backblaze B2 protocols. It supports SSL/TLS, IPv6 and FXP, and features a transfer queue, proxy and firewall support, multiple connections, chmod features and drag-and-drop. The software uses the Windows API for its interface. It is available for both IA-32 and x64 editions of Windows.
In computing, SSHFS is a filesystem client to mount and interact with directories and files located on a remote server or workstation over a normal ssh connection. The client interacts with the remote file system via the SSH File Transfer Protocol (SFTP), a network protocol providing file access, file transfer, and file management functionality over any reliable data stream that was designed as an extension of the Secure Shell protocol (SSH) version 2.0.
Dropbear is a software package written by Matt Johnston that provides a Secure Shell-compatible server and client. It is designed as a replacement for standard OpenSSH for environments with low memory and processor resources, such as embedded systems. It is a core component of OpenWrt and other router distributions.
WISE-FTP is an FTP client for Microsoft Windows that is developed and distributed by the German company AceBIT, located in Darmstadt. Apart from using the normal FTP protocol, Wise-FTP supports the SSH (SFTP) and FTPS (FTP/SSL) protocols, as well as the SSL and TLS cryptographic protocols. Transfers can be carried out via drag and drop, as the program interface is based on Windows Explorer.
Sysax FTP Automation is a Secure file transfer automation program for the Windows operating system. It consists of a script generation wizard, script editor and debugger, and a task scheduler. It also contains a secure command line FTP Client program called sysaxftp.exe that is a secure drop-in replacement for the ftp.exe command line program. In addition to FTP, secure file transfer using SSL/TLS (FTPS) and SSH2 (SFTP) are supported. The software is certified for Windows Vista, and tested to be compatible with Windows 7. The software is also certified for Windows Server 2012 and runs on all 32 and 64 bit editions of Windows from Windows 2000/Windows XP to Windows 8/Windows Server 2012. The Personal edition of the software is free for non-commercial use.
AbsoluteTelnet is a software terminal client for Windows that implements Telnet, SSH 1 and 2, SFTP, TAPI Dialup and direct COM port connections. It is commercial software, originally released in 1999 and is still in regular development by Brian Pence of Celestial Software.
OpenSSH is a suite of secure networking utilities based on the Secure Shell (SSH) protocol, which provides a secure channel over an unsecured network in a client–server architecture.
Bitvise is a proprietary secure remote access software developed for Windows and available as a client and server. The software is based on the Secure Shell (SSH) protocol, which provides a secure channel over an insecure network in a client-server architecture.
