The files on PyPI have these hash values:

• SHA256
• MD5
• BLAKE2-256

If print the hash values, people can easily verify whether the file on PyPI was automatically uploaded by CI script.
It is best to print a pretty-print table.

We need to select, use and promote the use of one of these:

• https://github.com/mahmoud/glom
• https://github.com/cdgriffith/Box
• https://github.com/mewwts/addict

* Need to do some comparison/analysis and choose what's best.
