OK, this was impossible to find anywhere, and I’m not sure anyone will find it here, either, but the SHA256 checksum of sha256sum.exe for Windows as downloaded today from labtestproject.com, for the file itself, is 4867ccab1c36f33dec005e83eef8dfb6d3b166941a72400aa3c963675c2a7dae.
The problem is I have no idea who labtestproject.com are.
