Hi Everyone,
Botan checked-in an implementation of SHACLA2 using Intel SHA intrinsics. Also see https://github.com/randombit/botan/pull/1151/files.
The Botan team was kind enough to allow us to use their encrypt function and release it under Crypto++ licensing terms, which is effectively public domain. The check-in of interest can be found at https://github.com/weidai11/cryptopp/commit/1ab1e08ac5b5a0d6.
SHACAL2 performance improved from about 27 cpb to about 8 cpb.
I'd like to look into an ARMv8 port, but its low on my priority list at the moment. OCB and ed25519 signatures are next on my hit list.
