Secure Shell Tunneling (or SSH Tunneling) is like having a secret tunnel that goes from one place to another. It's like a tunnel that only you can use to move something (like a file or a message) from one place to another without anyone else seeing it or knowing it's there. The tunnel has locks and walls that keep people from being able to find out what's inside it, even if they are trying to look for it. It's like having a secret door that only you can open.
