See if these are worthwhile vs using OpenSSL for the hashlib algorithms it supports.  OS APIs can in theory take better advantage of HW acceleration for performance.  Verify this on supported architectures.  Regardless it would allow some things to be fast if someone wanted to use a build without OpenSSL.

I'm not a Windows or Microsoft user.  I'm filing this for completeness, someone else would need to do the work.

Did a basic test (with timeit and a work-internal library I already have) and the native functionality is *slightly* faster than OpenSSL.

But I think it's worthwhile anyway, to help reduce our dependency on OpenSSL.
