wherever you share your email address, so that people can double-check that
they have the correct public key when they download yours from a keyserver.</p>
-<p class="notes">You may also see public keys referred to by their key ID,
-which is simply the last eight digits of the fingerprint, like C09A61E8 for
-Edward. The key ID is visible directly from the Key Management window. This
-key ID is like a person's first name (it is a useful shorthand but may not be
-unique to a given key), whereas the fingerprint actually identifies the key
-uniquely without the possibility of confusion. If you only have the key ID,
-you can still look up the key (as well as its fingerprint), like you did in
-Step 3, but if multiple options appear, you'll need the fingerprint of the
-person to whom you are trying to communicate to verify which one to use.</p>
+<p class="notes">You may also see public keys referred to by a shorter
+key ID. This key ID is visible directly from the Key Management
+window. These eight character key IDs were previously used for
+identification, which used to be safe, but is no longer reliable. You
+need to check the full fingerprint as part of verifying you have the
+correct key for the person you are trying to contact. Spoofing, in
+which someone intentionally generates a key with a fingerprint whose
+final eight characters are the same as another, is unfortunately
+common.</p>
