For other uses, see SSH (disambiguation). Secure Shell (SSH) is a cryptographic network protocol for operating network services securely over an unsecured network. The best known example application is for remote login to computer systems by users.
The Secure Shell protocol version 2, or SSH2, specifies how a client can connect securely to an SSH server, and then use the resulting secure link to access the server's resources.Among other things, the client can run programs; transfer files; and forward other TCP/IP connections over the secure link.The SSH2 protocol is a descendant of the SSH v1.x series of protocols. SSH version 2 is standardized at IETF, and the vast majority SSH implementations now support SSH version 2.SSH version 1 is less secure, and is almost no longer being used.mong other things, the client can run programs; transfer files; and forward other TCP/IP connections over the secure link.
