Secure Shell (SSH) is a cryptographic network protocol for secure data communication over unsecured networks. It provides a secure way to access remote servers, transfer files, and execute commands.

Key Features of SSH

  • Encryption: Protects data using strong cryptographic algorithms 🔒
  • Authentication: Supports public-key authentication with SSH keys 🔑
  • Portability: Works across different operating systems and devices 📱💻
  • Versatility: Enables remote command execution, file transfer, and tunneling 🛠️

How to Use SSH

  1. Generate SSH Keys
    Use ssh-keygen to create a key pair.

    SSH_Key

  2. Connect to a Server
    Execute ssh username@hostname for secure remote access.

    Secure_Connection

  3. Enable SSH Service
    Ensure the SSH daemon is running on your server.
