I did, but I only get results relating to the "stripping" attack,
which downgrades from HTTPS to HTTP.

Obviously that would cause a reduction in security... But what I'm
suggesting is the opposite: redirecting from HTTP to HTTPS.

How could that reduce security?

(sigh)

I must say I'm surprised so many people think it's a good idea to
leave cygwin open to trivial MITM attacks, which is the current state
of affairs.

This is my opinion only of course, but if cygwin wants to have any
security credibility, it should simply disallow non-SSL downloads of
setup.exe. Otherwise the chain of authenticity is broken forever.
