What Exactly is SSH Tunneling?

SSH (Secure Shell) tunneling is a technique used to encrypt data transmissions between two devices across an unsecured network. By establishing an SSH tunnel, you can securely transfer data, access remote servers, and bypass network restrictions.

The process involves creating an encrypted connection between your local machine and a remote server. Once the tunnel is established, all traffic passing through it is encrypted, rendering it difficult for unauthorized parties to intercept or decipher the data.

SSH tunneling is widely employed for:

Securing remote server access
Overcoming firewalls and censorship
Protecting sensitive information during transmission
