How are GPG keys generated on a smart card?

I chose to generate my GPG keys on an air-gapped (non-network connected) Debian LiveCD to prevent any accidental leakage of my keys.

This setup makes use of a Smartcard paired with a small form-factor Smartcard reader to effectively create an OpenPGP USB “token.” ( Note: This reader does NOT have an external PIN pad for secure PIN entry, so if that’s a concern for you, you should consider another type of reader.) I like this solution because it’s compact and convenient.

After three incorrect entries of the user PIN, the card becomes “blocked” and can only be “unblocked” by entering the admin PIN. After three incorrect entries of the admin PIN, the card is destroyed. This prevents abuse should the card fall into the wrong hands.
