Red Hat DIRECTORY SERVER 8.1 - 11-01-2010 Instrukcja Użytkownika Pobierz pdf (Strona 48)

Now let's have a look at a signed message I received from

[email protected], assuming I have his public key:

The OpenPGP status bar tells that the signature is valid, although untrusted.

This is mostly normal, and just means that John Random Hacker's public key

has a trust lower than ultimate in my public keyring, which is the default for

freshly imported keys. As we explained earlier in Section 7.7.2. , trust is

subjective and related to how we obtained someone's public key. The most

important point here is that OpenPGP verified that the message has been

correctly signed with the specified public key.

Note that the colour of the OpenPGP status bar is now blue. Accordingly, a pen

with a question mark is shown near the email headers and in the bottom right

corner.

From the Details menu you can operate directly on the sender's key:

• View OpenPGP PhotoID allows you to see the PhotoID, if any;

• Sign Sender's Key... allows you to sign the sender's key;

• Set Owner Trust of Sender's Key... allows you to set the sender's key to

the desired trust.

These are just shortcuts, you can do the same operations from Key

Management as well.
