New submission from Gregory P. Smith <greg at krypto.org>:

https://developer.apple.com/documentation/cryptokit/ in macOS 10.15+

This is a common place for platform specific hardware acceleration to be exposed to the user (especially on SoCs which often have non-standard hardware - Like Apples... which is presumably why they create this).

What they offer is limited, but when present and running on a recent enough macOS, using their and SHA2 and HMAC(SHA2) implementations as well as Insecure.SHA1 is probably better than OpenSSL's.  **Verify this.** It'd also allow those to be fast in a non-openssl build (as if anyone does those).

I know little about mac building and packaging and how to have something target an older OS and use a 10.15+ API. So if this winds up only being used from aarch64 macOS builds (10.15+ by definition IIRC?) that could also work.

I leave this issue for a macOS Apple API friendly person to take on.

This issue is cousin to the Linux one: https://bugs.python.org/issue47102
