The data transferred between the client and the server is encrypted using industry-standard strong encryption algorithms (such as AES), and the data is also hashed to ensure the integrity of the data being transferred. During the setup, symmetric encryption is agreed upon, and keys are exchanged to continue the communication via symmetric encryption. Once the connection is established between the SSH client and the SSH server, the data is encrypted using the parameters that were exchanged during the setup. Secure Shell protocol, or SSH, is a way to operate network services in a secure manner over an unsecured network. Using SSH protocol to communicate can be beneficial as SSH provides strong encryption over the messages transferred and also integrity protection against any attacks. We can have automated secure file transfers, automated systems, and also bulk configuration management which can turn out to be helpful. Secure Shell (SSH) is a cryptographic protocol and interface for executing network services, shell services and secure network communication with a remote. SSH Key-based authentication is primarily used to enable security automation. These private keys are also called SSH Keys. The public key is configured to the server, and anyone with the private key is granted access to the server and authentication respectively. There are two keys namely, the public key and the private key. Public Key authentication is mostly used for automated purposes and system administrators for single sign-on. The most common ones being passwords and public key authentication. Several options can be used for user authentication. Source: What kind of authentication can be used with SSH? Following the setup, SSH protocol uses strong symmetric encryption and hashing algorithm to ensure privacy, and integrity of the data exchanged. SSH client would drive the connection set up process and use Public Key Infrastructure to verify the authenticity of the SSH server. SSH protocol works in a client-server architecture, thus an SSH client connects securely to an SSH server. Managing network infrastructure and other mission-critical system components.Interactive and automated file transfers. ![]() Providing secure access for users and automated processes.We can use SSH protocol in various scenarios such as: SSH provides strong password and/or public key authentication using which a sysadmin or network admin can connect to any computer or application remotely, execute commands and also move files using SFTP or SSH File Transfer Protocol. SSH or Secure Shell or Secure Socket Shell is a network protocol is how users, sysadmins can access other computers over an unsecured network. ![]()
