SSH Key-Based Authentication
Generate SSH key pairs, deploy public keys to servers, and disable password authentication for enhanced security.
Unlock SSH with Key Pairs
Welcome! In this lesson, you'll learn about SSH key-based authentication. This method is far more secure and convenient than using traditional passwords for logging into your server.
SSH keys act like a digital handshake, proving your identity without needing to type a password every time.
Public & Private Key Magic
SSH key authentication relies on a pair of cryptographic keys:
- Private Key: This key stays on your local machine and must be kept secret. Think of it as the unique key to your digital lock.
- Public Key: This key is placed on the server you want to access. It's like a special lock that can only be opened by your private key.
When you try to connect, the server challenges your client, which then uses your private key to prove its identity.
