Use of SHA ISA Extensions

[jblomer]

Hello,

We noticed that LibreSSL is not using the x86 SHA instruction extensions. In our benchmark, we see about a factor 2 slower SHA-1 performance of LibreSSL compared to OpenSSL (Core i5-12600H).

It appears that support for the SHA extensions was added to OpenSSL just after LibreSSL's fork.

Is there a plan to add support for SHA extensions in LibreSSL; is it something you'd consider adding?

Thanks!
