The 'nettle_sha256_compress' function doesn't exist in any header file from nettle that I've looked at. The '_nettle_sha256_compress' function exists as a symbol in the .so library, but it is clearly not intended for public usage: $ nm -a -D /usr/lib64/libnettle.so | grep sha256_compress 0000000000027730 T _nettle_sha256_compress@@NETTLE_INTERNAL_8_4 So this #define magic is definitely not something we can do. IOW, unless I'm missing something, I don't think we can even use nettle for your desired goal, which leaves us no impl at all.
