Sumber: https://makandracards.com/makandra-orga/13644-what-to-do-when-your-gpg-pgp-key-expires

Suggested way: Extend your key expiry

• Find the ID of the expiring key, e.g. with

gpg --list-secret-keys

Note your key ID (after the slash).

• Start editing the key with

gpg --edit-key KEY_ID

• View your selected key and subkeys with

list

• Select the primary key with key

0

• Interactively select a new expiry with expire. You'll probably have to unlock your key with its passphrase.
• Select the primary subkey with key 1 and repeat step 5.
• Inspect the resulting expiries with list.
• Issue a save when you're done.
• Publish your updated key (as described previously), e.g. gpg --keyserver keyserver.ubuntu.com --send-keys KEY_ID
• commit your key as fallback to keys.makandra.de (see here)
