[openssl-dev] [openssl.org #3897] request: add BLAKE2 hash function (let's kill md5sum!)

[Jean-Philippe Aumasson]

The status of the draft is unchanged ("Finding Reviewers"). Perhaps OpenSSL
can speed up the review process.

BLAKE2 has a keyed (aka MAC/PRF) mode, so it may also replace Poly1305. A
BLAKE2 MAC can be customized wrt key or tag size, and can provide the
highest security level for a give key/tag size combination.
