We should look at the existing IANA registry of hash functions. The HTTP Auth WG is also close to publishing an update of the Digest auth spec with SHA-2 (256 + 256/512) added.

Neither the keyword nor the description is clear as to which SHA generation is being used. Is this SHA-0 or SHA-1? Do we need to define additional keywords to bring this up-to-date?
