Extending the life of your keys
As you can see in the image above, you can extend the life of your keys using thebutton. Simply choose the new date from the popup calendar. To do this, however, you must have access to the private key and its pass-phrase. Without them you can do nothing.
Change your passphrase
Should you suspect your passphrase is compromised, you can change this also from the Key Properties dialogue. Thebutton is below .
Revoking a key
If you lose your private key or think it has been compromised in some way you need to revoke it. To reliably render a key unusable you need to revoke it. Revoking is done by adding a special revocation signature to the key.
The revocation signature can be created together with the key. In this case it is stored in a separate file. This file can later be imported into the keyring and is then attached to the key rendering it unusable.
If you have not created such a detached revocation on key creation you can create such a revocation signature at any time choosing , optionally importing it to your keyring immediately.
A full illustrated manual helps you through some details.
If you are not in a position to physically verify the identity of your contacts you should especially read the key-signing section which explains the benefits of local-signing.
