Re: feature request for coreutils: b2sum

[Zooko Wilcox-OHearn]

Folks:

Earlier in this discussion Pádraig Brady asked ¹ if we had submitted
BLAKE2 for inclusion in openssl. We have ², but they haven't yet
included it ³.

Eventually, I think, openssl will support highly optimized
implementations of BLAKE2, but I think it will be a long time before
that is widely deployed and GNU coreutils can rely on it.

In the meantime, could we go ahead and use the portable C reference
implementation ⁴, or the even smaller RFC implementation ⁵?

Here is the code for the "b2sum" command-line tool that comes with the
reference implementation: ⁶

Regards,

Zooko
