What is SSH Keys?

SSH keys are a secure way to authenticate to a remote server. They use cryptographic key pairs (a public key and a private key) instead of passwords. The public key is placed on the server, and the private key is kept securely on the client. When connecting, the client uses the private key to prove its identity. This method is generally more secure than passwords, as it's much harder to brute-force and eliminates the risk of password compromise.
