8.2.2. Verifying a signature

Now, if your mailclient is set up so that a copy of outgoing emails is

automatically saved in the Sent folder, it is possible to have a look at how the

signed message looks like:

In this Message window, the OpenPGP status bar shows up to indicate that the

message is secured with OpenPGP.

The status bar says that the message was correctly signed, and gives

information about the sender's key, i.e. the key that was used to sign. This

information is the user ID (the identity of the signer i.e. name and email

address) and the key ID. The status bar also reports the date and time of the

signature. You can expand or shrink the status bar by clicking on the expand

button on the left.

The OpenPGP status bar is green to indicate that the sender's key is trusted. In

fact, in this case the sender's key is my own key, which has ultimate trust in my

own Enigmail environment. Accordingly, a picture of a signing pen is shown

near the email headers, and the pen icon is green.

You can have more details about the signing process (in this case, the

fingerprint of the signing key) by selecting Details → OpenPGP Security Info...

or simply by clicking on the picture of the pen. Details → Copy OpenPGP

Security Info copies the security information to the Clipboard instead.
