SSH (SecureShell) is a security protocol built on the application layer and transport layer. It provides a secure transmission and application environment for the Shell on the computer. SSH can effectively prevent information leakage during remote management. It is applicable to multiple platforms. SSH is composed of client and server software. The client contains SSH programs, remote copy scp, remote login to slogin, Secure File Transfer sftp, and other applications. The server is a daemon process, it runs in the background and responds to connection requests from clients. Because of the encryption algorithm
