Extending the life of your keys
As you can see in the image above, you can extend the life of your keys using the
button. 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. The
button 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.
note that to import this signature to the key no password is required. Therefore you should store this revokation signature in a safe place, usually one that is different from you key pair. It is a good advise to use a place that is detached from your computer, either copy it to an
external storage device like an USB stick or print it out.
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.
Un completo manuale illustrato ti aiuta con tutti i dettagli.
Se non sei in grado di verificare fisicamente l'identità dei tuoi contatti dovresti in particolare leggere la sezione gestione delle chiavi che spiega i benefici della firma locale.
