I haven't found any Intel hardware with the SHA extensions actually implemented. I was expecting it in Skylake but apparently that's not the case... Not sure when we can expect to see them.
- silotis 9y agoRight now the most common x86 CPU which implements the SHA instructions is AMD's Ryzen. The only available Intel CPU which supports them is Goldmont, the latest generation of Atom CPU. It seems likely that Cannon Lake and possibly Coffee Lake will also implement them, but I haven't seen any rumors pointing one way or the other.
- mtgx 9y agoIntel has recently implemented SHA1 in hardware. So give it another decade or so.
- ko27 9y agoSHA-1 & SHA-256 were both implemented at the same time. https://en.wikipedia.org/wiki/Intel_SHA_extensions https://en.wikipedia.org/wiki/Intel_SHA_extensions
- baby 9y agohopefully SHA-3 (or better, the Keccak permutation) is implemented in hardware first.
- snakeanus 9y ago> SHA-3 (or better, the Keccak permutation) SHA-3 is just Keccak with specific capacities. If you mean that they should not implement only the standard SHA-3 functions then I agree, having c/raw/SHAKE256 as well would be nice.
- baby 9y agoImplementing the permutation would be even better, because other stuff like Strobe, Keyak, Ketje, etc... could use it.
