|The PGP_MIME page will talk you through setting up and using GnuPG|
A web of trust comprises a group of persons who trust each other. To show their trust, they have signed each other's keys. gpg allows you to do this.
The web of trust is extended in key signing parties that go like this:
Your private key is stored in "secring.gpg", your public one is stored in "pubring.gpg". You keep your private key secure, and are free to distribute your public key.
gpg --list-keys /home/me/.gnupg/pubring.gpg ---------------------------------- pub 1024D/45E377BB 2008-02-03 [...]
gpg --search-key me@home
gpg --sign-key 45E377BB
gpg --send-key 45E377BB
|yours may be called 'secring.pub'|
Then call kgpg and set your trust on your private key to "ultimate."
Whatever problems arise, first make sure your gpg is properly set up:
gpg: no ultimately trusted keys found
Call kgpg and set the trust of your private key to "ultimate'"
You get an error message like this whenever you start up? You need scripts to make it start and stop cleanly. You can get scripts here:
Copy them into your ~/.kde/env and ~/.kde/shutdown folders, check permissions, and make sure they are executable.
Check which pinentry packages you have installed. You may find you are missing pinentry-qt4.
From time to time you need to do some maintenance work on your keys. KGpg was written to make this easier. There you will be able to extend the life of your keys, refresh them if they have already expired, change your passphrase, or revoke a compromised key.
