Comment(by karsten):

 Robert, do you have a list of things that need to be checked in order to
 verify the various descriptors?  Here's what I do for server descriptors,
 certs, and consensuses:

 Verify server descriptors using the contained signing key.  Verify that
  1) a contained fingerprint is actually a hash of the signing key and
  2) a router signature was created using the signing key.

 Verify consensuses using the separate certs.  Verify that
  1) the fingerprint in a cert is actually a hash of the identity key,
  2) a cert was signed using the identity key,
  3) a consensus was signed using the signing key from the cert.
