The term SFTP can also refer to Secure file transfer program, a command-line program that implements the client part of this protocol. As an example, the sftp program supplied with OpenSSH implements this. [10] Some implementations of the scp program support both the SFTP and SCP protocols to perform file transfers, depending on what the server ...
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. [1]
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]
The SCP is a network protocol, based on the BSD RCP protocol, [5] which supports file transfers between hosts on a network. SCP uses Secure Shell (SSH) for data transfer and uses the same mechanisms for authentication, thereby ensuring the authenticity and confidentiality of the data in transit.
SFTP may refer to: Computing. SSH File Transfer Protocol, a network protocol used for secure file transfer over secure shell Secure file transfer program, an SSH ...
Some protocols—including FTP, FTP Secure, FASP, and Tsunami—listen on a "control port" or "command port", at which they receive commands from the client. Similarly, the encryption scheme indicated in the "Encryption" column applies to transmitted data only, and not to the authentication system.
For example, if some host needs a password verification for access and if credentials are provided then for that session password verification does not happen again. This layer can assist in synchronization, dialog control and critical operation management (e.g., an online bank transaction).
SSH File Transfer Protocol (SFTP), a secure alternative to FTP (not to be confused with FTP over SSH or FTPS) Files transferred over shell protocol (FISH), released in 1998, which evolved from Unix shell commands over SSH; Fast and Secure Protocol (FASP), aka Aspera, uses SSH for control and UDP ports for data transfer.
