This is a SHA-256 implementation that allows for setting and getting the mid-state information. This was needed to enable repeated hashing against a (potentially large) fixed prefix.
The original version of this was written in Python. While the Cython version will be much faster, this is not a highly optimized library and relies on the native C compiler for optimization.
This repository does not contain the generated C code from Cython. To recreate the C code run the cytnonize step via::
python3 -m pip install --upgrade build
python3 -m build
The original author was Thomas Dixon for a python version of this code. Sam Rushing added the midstate access and converted it to Cython_. Nigel Drego added the context state setter/getter.
