It might look like this, bit it is not a connection to a remote machine
but connections to the local machine itself (localhost,
This is the only reliable interprocess communication mechanism on
Windows which does not allow to be used by remote boxes.  What we do is
to emulate "Unix Domain Sockets" by "TCP IPv4 sockets"; the server sites
(e.g. gpg-agent or kleopatra) are only listening for local connections.

The Internet's CA infrastructure is highly insecure and an easy vector
to introduce all kind of malware.  The problems are known for more than
a decade but only recent events made them appear above sea level.  There
is a reason that all browser vendors are now trying to implement
workarounds for this systems (certificate pinning, Perspective, etc.)

Thus you might be better off, checking a certificate yourself and most
important check the SHA-1 checksums, we provide on the website _and in
announcement mails.  Note that the vanilla installer is pretty new and
we may have messed something up while uploading the file.

I hope I could shed some light on it and made the flags turn a bit more
into the green.
