#2Are aes instructions new in aarch64 processors? I'm surprised this doesn't work magically "out of the box", but I'm not up to date with this stuff.
Also, this is another really good reason never to use a sha2 as your hashing algo for password storage.

#3... by moving from a software implementation to a mostly hardware one. ;)
Still a worthwhile article but the title seemed to make me think of implementation/algorithm changes.

AES and SHA2 are completely different algorithms.

I don't know what you mean by this. I understand that SHA2 is poor for some things, but I'm not sure how this illustrates that.

SHA2 just got even faster, so it illustrates rather well that you wouldn't want to use it for password storage -- of course that was always true, but the improvement drives that point home.

#6So with hardware sha256, can this mine bitcoin cheaper than an ASIC?

Most of crypto hashes implementations in Go are hand written assembly for specific platforms.

#8ok mentioning Go here is a bit pointless. How did Go help compared to any other language when Arm has hardware instructions for SHA1&2?

It was a typo in my post, I meant sha2 and not AES.

or find the private key of a bitcoin address faster?
