I didn't want to make such high requirements. At the moment, problems
are worse, most downloads (http) aren't even as safe as TLS.

Any tool as safe as TLS and also defeating your + is of course welcome
as well.

As far I know, Thandy is unfinished, no longer developed, Tor package
centric, derived from TUF, downloader. Therefore not useful for the
general use case?

TUF is awesome. They're creating a library, others can use in their
applications. But then we're back to the original problem of this
thread: how to get this application in the first place and at least as
safe as TLS?

This is awesome as well, but I believe it solves a different problem.
This one was: how to initially download? Then you're back to OpenPGP,
which very few people use.

So you're working with Debian/upstream to integrate OpenPGP verification
better into the operating system?
