Subject: Re: RFC v3: Another proposed hash function transition plan

Hi Johannes,
> SHA-256 got much more cryptanalysis than SHA3-256 […].
I do not think this is true. Keccak/SHA-3 actually got (and is still
getting) a lot of cryptanalysis, with papers published at renowned
crypto conferences [1].
Keccak/SHA-3 is recognized to have a significant safety margin. E.g.,
one can cut the number of rounds in half (as in Keyak or KangarooTwelve)
and still get a very strong function. I don't think we could say the
same for SHA-256 or SHA-512…
Kind regards,
Gilles, for the Keccak team
