解析 Secure Shell (SSH) is a cryptographic network protocol for secure remote login and other secure network services over an insecure network.The standard TCP port for SSH is 22. The best known example application is for remote login to computer systems by users.
SSH provides a secure channel over an insecured network in a client-server architecture, connecting an SSH client application with an SSH server. Common applications include remote command-line login and remote command execution, but any network service can be secured with SSH. The protocol specification distinguishes between two major versions, referred to as SSH-1 and SSH-2.
The most visible application of the protocol is for access to shell accounts on Unix-like operating systems, but it sees some limited use on Windows as well. In 2015, Microsoft announced that they would include native support for SSH in a future release.
