Since this has come up a few times in the past months, I guess I'm
curious as to what the correct 'round-one' implementation of
cryptographically enabled key-servers would would be. Is it:
(1) Verifying that the keydata hasn't been tampered with, like editing
in a hex editor?
(2) Only accepting keydata that has been signed by the key owner?
(3) Possibly accepting keydata signed by trusted keys, for example peer
keyservers that that also perform the same verifications?
(4) Possibly saving the signature as well, so peer keyservers can
optionally perform the same verification at step (2) when you sync?
Or am I totally off base here?
