Imagine a vast, ever-changing land filled with digital fortresses: servers storing our precious data. Guarding these fortresses is crucial, and one of the most trusted tools in this realm is the SSH key, a digital equivalent of a super secure lock and key.
The Key Duo: Public and Private
An SSH key is like a key pair with two parts: a public key and a private key. Think of the public key as the fancy lock on your gate, visible to all. Anyone can see it, but only those with the right key (the private key) can unlock it.
The private key, on the other hand, is like the master key hidden under your doormat. You keep it close and never share it with anyone. It's the key that grants access to your digital castle.
