I've sent a mail to the GPG list asking for guidance and some more support
in GPG for this.. It looks like I'll change the field to
Depending on if the keyID is an important distinguishing mark (the 6d..
number is the untruncated keyID) R indicates it is an RSA key and the D is
DSA (to prevent attacks across keytypes)
Here is an interesting question - For all the signing parties that go on,
how are the keys ID'd? I'd hope the use the full bizzillion number ID I
give above, but no tools print the full keyID very easially.
