Well, as I've said, SPKI is developing nicely. It has not yet been standardized and the formats are still flexible, which is a benefit for Coda since if there are any deficits in the formats they could still be fixed. SPKI is also (relatively) simple in concept and design. > As was suggested in a later email, SPKI is certainly a possibility -- what > I'd really like to see is a standard interface to the variety of > certificate systems out there so that we can plug in arbitrary PK systems > as we need to, be it SPKI, X.whatever, or DNSsec.

You might find this is hard, given that they all have very different ideas about trust and how naming works. PerryReceived on 1998-03-31 12:08:56
