The sample size of responses seems too small to reach a meaningful consensus. Perhaps posting something a bit more controversial will get the silent majority to speak up. :-) To wit: - Assign explanatory names only to usages 2 and 3: 2 - TRUST-ANCHOR 3 - END-ENTITY - Since usages 0/1 merely complicate DANE implementation without[*] enhancing security, they can remain anonymous, or be given names that clearly indicate that these are discouraged/deprecated. 0 - SECURITY-THEATRE-0 1 - SECURITY-THEATRE-1 This would remove all confusion about the DANE usages. If someone can justify the existence of 0 and 1 in a pair of pithy acronyms then those are the names. Otherwise, out they go! [ I have begun design/implementation of general-purpose DANE support for OpenSSL. Supporting all four usages is rather more complex than one might imagine, and is largely wasted effort, but the protocol requires 0/1 for now, so I have no choice. I would be thrilled to bits were the above to be taken seriously, and usages 0/1 dropped from DANE TLSA in a future revision of the protocol. ] -- Viktor. * If DNSSEC *is not* compromised, 2/3 are sufficient. If DNSSEC *is* compromised, the attacker will publish 2/3, thus a domain owner's use of 0/1 offers no protection against DNS attacks. There will be no measurable deployment of out-of-band mechanisms that harden 0/1 or application protocols that implement DANE, with just usages 0 and 1.
