It uses a hash function to generate a hash code from the received data. Hashing: Hashing is an authentication technique that is used to ensure whether the received data is coming from a genuine sender and is unaltered or not.There are three major encryption techniques which are used by the SSH. The SSH protocol is more secure as compared to other protocols such as telnet, and the encryption techniques are quite good than other protocols. After copying this key to a remote host, we can establish a connection using the SSH key, not by the password. It is recommended to hide the private key for security purposes, copy the public key to the remote host. The ssh-keygen command creates two files, and, which contain private and public key, respectively. We can see from the above output, the ssh keys have generated. The above command will generate the public and private keys for creating a connection to the host system.

#SSH SHELL LINUX INSTALL#

To install the OpenSSH client, execute the below command: If any Linux system does not have the ssh client, we can install it manually by using the package manager. The OpenSSH client comes preinstalled with most Linux distributions. It performs remote operations using these ssh utilities. This client package contains other SSH utilities like sftp, scp, and ssh that are installed by default with the ssh command. It is also called as ssh and can be invoked from the Linux terminal. The OpenSSH client is a connectivity tool for the systems to connect two systems with the ssh protocol. The default SSH protocol version for SSH server and SSH client communication is version 2. If the provided information is verified, the SSH protocol establishes a new connection for the available environment. Once the client initiates a connection, the host responds with the necessary information and exchanges the credentials. The server (Host) contains an SSH process that is ready to take a request for the client connection through a TCP/IP port. The client uses the specified host information to establish the connection if the provided credential verified, it will establish an encrypted connection.

Also, we require a ssh client to connect with another computer or server. To establish an SSH connection, we need two primary components a client and a host, which can be a server, domain name, IP address, and more. A domain name or an IP address also refers as Host.

Host: A host is a machine that is being accessed by the user, such as a computer or a router.

User name: User name is the name of the Linux user, which is being accessed by the host machine.

ssh command: It instructs the machine to create a secure encrypted connection with the host system.

The ssh command consists of three different types of components:
