Key Fingerprints are a shortcut way of verifying a key. They are
commonly used to determine if you have the correct key.
For instance, you could call me on the telephone and read off the
fingerprint. This would be a lot easier than reading the entire
key. Fingerprints are actually an MD5 hash of the key bits. You end
up with a 32 hex char fingerprint. Note that the one
"anonymous" lists below is not valid. The KeyID (8 hex char) is more
commonly used to identify keys, and makes more
sense for inclusion in your .sig file, especially since key servers
typically offer the ability to search by KeyID, but not
fingerprint. The KeyID is 32 bits stripped off the end of the public
key modulus.
Keep in mind that it is relatively trivial to create a new key with
the same fingerprint or KeyID as another, although creating
one that duplicates both is probably too far out. Neither are
guaranteed to be unique. Valid keys themselves should always be
unique (until the algorithms are broken). Of course, in order to
trust a key, you really need to rely on signatures, not IDs or
fingerprints.
Basically, use the KeyID in your sig, verify with the fingerprint.
