Malware easily steals software-based keys when your laptop gets hacked. Enter YubiKey-Guide on GitHub. It is the ultimate step-by-step tutorial for generating GPG and SSH keys in a secure, air-gapped offline environment, then locking them inside a hardware token. It covers offline master keys, daily subkeys, and agent forwarding. Once on the YubiKey, your private keys can never be extracted. Even if your PC is fully compromised, your digital identity remains physically isolated and safe.
