Replicating __mm256_shuffle_epi8 Intrinsic

[Michael Ennen]

 I am trying to implement SHA-256 using the new Java Vector API.

I have read the API docs but crossing the large mental gap of SIMD
instructions to the API for someone who knows very little SIMD has been
insurmountable for me.

My question has been asked on Stack Overflow:

https://stackoverflow.com/questions/68135596/replicating-mm256-shuffle-epi8-intrinsic-with-java-vector-api-shuffle

It is quite a simple (to ask anyway) question, which is, how to replicate
the _mm256_shuffle_epi8 intrinsic with the Java Vector API?

Thanks very much.
