What is the rationale to implement all sha3 variants?
I agree, I'd like to see a really good rationale.
I understand some protocols need lower grade versions for performance
reasons but that seems to matter a lot less for openpgp usage. Why not just
implement sha3-512?
One would be good. Suits me to go for the longest one.
How about this:
ID Algorithm Text Name
-- --------- ---------
snip
12 - RESERVED
13 - RESERVED
14 - RESERVED
15 - SHA3-512 [FIPS202] "SHA3-512"
And while we're at it, can we add DEPRECATED to all the rest except
SHA(2)512 ?
Discussion in CFRG was definitely pointing to using 512 for the hash
required for the internal bit. So if we choose one it should be 512 and
truncate where necessary in the UI part.
