Hi

May you please include a list of SHA-256 hashes for the downloads in
https://www.gnu.org/software/emacs/download.html

This will provide an easy and secure way to verify downloads
Please note that the experience to verify the signature on windows is very poor
and it for me at least ended up with the file nor being verified because of missing public key

A SHA-256 hash will be a simple solution

Thanks
Ali
