  KGpg er en grafisk brugerflade til gpg's kommandoer


GnuPG krypterer og afkoder dine emails og udvalgte filer. Der er mange muligheder for at gøre dette fra kommandolinjen, men med KGpg bliver det nemmere - du behøver ikke at huske de mange kommandoer. KGpg kan hjælpe dig med at lave og håndtere dine kodenøgler, importere og eksportere nøgler, vise nøglernes signaturer, hvor meget tillid, du kan have til dem og hvornår de udløber. Faktisk kan du gøre alt, hvad du har brug for med KGpg. Der er en dialog til at hjælpe dig med at lave dine nøgler.

KGpg er integreret i Konqueror og Dolphin, hvor du ved hjælp af en højrekliksmenu kan kryptere en fil med eller uden signering.

Extending the life of your keys

As you can see in the image above, you can extend the life of your keys using the Change Expiration 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 Change Passphrase button is below Change Expiration.

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.

Warning

Please

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 Your Key -> Revoke key, optionally importing it to your keyring immediately.

Note

Currently this item is only available in the context menu. This is likely to be moved from the context menu to the key menu for 4.7.1.


Tip

Når du starter KGpg med standardindstillinger vil den gemme sig i statusområdet. Hvis du startede KGpg og ikke ser den nogen steder, så kan du sandsynligvis nå den ved at udvide Plasmas statusområdewidget.


Tip

Hvis en kontakt har mere end en nøgle - måske nogle gamle nøgler foruden den aktuelle - og den forkerte nøgle bruges til kryptering, så find de gamle nøgler og reducer deres Ejer-tillid til Jeg betror ikke. De gamle nøgler vil stadig være tilgængelige til dekryptering af gamle meddelelser, men vil ikke blive brugt til nye.


En fuldt illustreret manual hjælper dig igennem alle detaljer.

Hvis du ikke har mulighed for personligt at verificere dine kontakters identitet, så er det særlig vigtigt, at du læser afsnittet om nøglesignering, som forklarer fordelene ved lokal-signering.
