Yes I really on TLS, no I'm not getting the archive necessarily from 
python.org. I might get it from a 3rd parrty that claims it's genuine.

Such party might be a Linux distro or another package manager (e.g. 
homebrew).

I can of course use GPG to verify it, but for quick check a sha512 sum 
works for me, while md5 not so much.

In Fedora, we use sha512 checksums [1]. In homebrew they use sha256 [2].
