duplicate keyid survey results
Mon Mar 4 03:12:01 2002
The thing that comes to mind immediately for me is that you should allow
for a 64-bit key-ID search.
When 32-bit key ID collisions occur, you may want your key server to
display a warning in the user-interface.
Remember that 32-bit collisions could be accidental, so not reporting them
would prevent the distribution of legitimate keys. (And you mention the
possibility of an intential DOS.)
I personally think that public key servers should do little more than
accept, store, and report data that it contains. Preventing the display of
keys with duplicate IDs steps over that line a bit too much for me.
