What is SSH?

Introduction

SSH (Secure Shell) is a cryptographic network protocol that enables secure communication between computers over a potentially unsecured network, like the internet. It is primarily used to remotely access and manage servers, devices, and systems. (ง ื▿ ื)ว

Capabilities of SSH:
  • Encrypted Communication: SSH ensures that data sent between the client (your computer) and the server is encrypted, which protects it from eavesdropping, tampering, or unauthorized access.

  • Authentication: SSH uses key-based or password-based authentication to verify the identity of the client and server before establishing a connection. The most secure form is public-key authentication, where a private key on the client is matched with a public key stored on the server.

  • Command Execution: SSH allows users to execute commands remotely on a server. For example, you can manage files, install software, or configure system settings as if you were physically at the server, all through the command line.
