How to extend PGP expiry date with GNU Privacy Guard

If you use GNU Privacy Guard (GnuPG / GPG) to manage your PGP keys on the command-line, here’s how to extend the primary key and a subkey for 3 months.

You’ll need to replace my key fingerprint with your own (that’s the long text starting A999).

Extend your key expiry

Open up a command-line terminal and type the following:

$ gpg --edit-key 'A999 B749 8D1A 8DC4 73E5 3C92 309F 635D AD1B 5517'
key 0
[repeat for subkeys: key 1, key 2 etc...]

If you get stuck, see the official GnuPG documentation.

Push it to the keyservers

Remember to push your updated key to the keyservers:

$ gpg --keyserver hkp:// --send-keys 'A999 B749 8D1A 8DC4 73E5 3C92 309F 635D AD1B 5517'

Remind your contacts to refresh their keys

Your contacts will need to refresh your key from the keyservers in order to be able to use your key again.

If a contact says your key has expired, you’ll know what to tell them.
