In this case, load the key data by clicking the button on the toolbar.
Once the key data is loaded or pasted into the text area, click
button on the toolbar. In a moment, the key will be

Key ID: 79547917824F601E User ID: Test Tester (Tester) <test@nomail> Creation Date: 2007-06-12 UTC Finger Print: 6BDAA1C88FD6657AB0394E4279547917824F601E
To authenticate a public key from others, it is highly recommended you verify the fingerprint of the key with the key owner. For example, you can verify the fingerprint of your friend's public key by calling your friend. It is imperative that you verify the fingerprint through an independent channel. For example, if you get a key from someone's website, it is not good to verify the fingerprint you generate with the fingerprint he posted on the same site.
To generate a fingerprint for a key, simply select the key ID from the list box. Its fingerprint will be shown in the text area along with other information.
When your friends call you to verify the fingerprint of your key, you need to generate the fingerprint of your key and verify the generated fingerprint with them over the phone. When you need to verify your friends' key fingerprints, first generate the fingerprints as described above, then call your friends. Once they generate their keys' fingerprints, they will verify the fingerprints with you over the phone.
If you have a key on your key ring, which you cannot verify, you can delete it.
To delete a key from your key ring, first select the key ID from
the list box. Then click
