The current version seems to accelerate AES and SHA families.
Size increase on x86_64 is <10k in our case.
It can make quite some performance difference; I tried
$ time ./result-dev/bin/nettle-hash -a sha256 /some/file/around/2G
And the total CPU time went down from 8.5s to 2s (single thread).
Now it matches the time of openssl
$ time openssl sha256 /some/file/around/2G
Of course, in real life it will be much harder to notice a difference...
Platforms without support for this (e.g. i686) seem to still build fine,
and ARMv7 cross-build also succeeds for me, so hopefully all is OK.
He prefers to contribute to his own nixpkgs fork triton.
Since he is still marked as maintainer in many packages
this leaves the wrong impression he still maintains those.
