<<SCP 35%
SCP (Secure Copy) is a means of securely transferring computer files between a local and a remote host or between two remote hosts, using the Secure Shell (SSH) protocol. Data is encrypted during transfer, to avoid potential packet sniffers extracting usable information from the data packets. The protocol itself does not provide authentication and security; it relies on the underlying protocol, SSH , to provide these features. For most applications, the SCP protocol is superseded by the more comprehensive SFTP protocol, which is also based on SSH.
<<SSH 35%
Secure Shell or SSH is a both an application for remote administration of Unix-like servers and a network protocol that allows data to be exchanged over a secure channel between two computers. SSH is typically used to log into a remote machine and execute commands, but it also supports tunneling, forwarding arbitrary TCP ports and X11 connections; it can transfer files using the associated SFTP or SCP protocols. Encryption provides confidentiality and integrity of data. SSH uses public-key cryptography to authenticate the remote computer and allow the remote computer to authenticate the user, if necessary. An SSH server, by default, listens on the standard TCP port 22.
