SSH (Secure Shell) is a network protocol that enables secure remote connections between two systems. System admins use SSH utilities to manage machines, copy, or move files between systems. Because SSH transmits data over encrypted channels, security is at a high level.
What is SSH used for?
SSH or Secure Shell is a network communication protocol that enables two computers to communicate (c.f http or hypertext transfer protocol, which is the protocol used to transfer hypertext such as web pages) and share data.
What is SSH and why it is used?
SSH or Secure Shell is a cryptographic network protocol for operating network services securely over an unsecured network. … SSH is generally used to access Unix-like operating systems, but it can also be used on Microsoft Windows. Windows 10 uses OpenSSH as its default SSH client and SSH server.
What is SSH and how does it work?
SSH is a client-server based protocol. This means the protocol allows a device requesting information or services (the client) to connect to another device (the server). When a client connects to a server over SSH, the machine can be controlled like a local computer.

What is SSL vs SSH?
SSH, or Secure Shell, is similar to SSL in that they’re both PKI based and both form encrypted communication tunnels. But whereas SSL is designed for the transmission of information, SSH is designed to execute commands. You generally see SSH when you want to log in to some part of a network remotely.
What happens during SSH?
SSH establishes a cryptographically secured connection between two parties(client and server), authenticating each side to the other, and passing commands and output back and forth. HOW SSH WORKS? SSH protocol uses symmetric encryption, asymmetric encryption and hashing in order to secure transmission of information.
What is ciphers in ssh?
SSH can be configured to utilize a variety of different symmetrical cipher systems, including AES, Blowfish, 3DES, CAST128, and Arcfour. The server and client can both decide on a list of their supported ciphers, ordered by preference.
