running a script on the web server. The latter would make mirroring
This would break for people who already use Torbutton, but at least we
can detect Torbutton's User-Agent string, time zone, and other
characteristics when it is enabled.

Moritz Bartl generates them and hosts them somewhere on
torservers.net. Unfortunately, the script currently puts each
package's GPG signature in a separate torrent from the package it signs.

GPA (the main GUI tool shipped in GPG4Win) doesn't provide a way to
check detached signatures, and GPGEx (the shell extension shipped in
GPG4Win) isn't compiled for 64-bit Windows. (I don't know whether
GPGEx provides a way to check detached signatures on 32-bit Windows
Windows does provide a way to check signatures on .exe files, but it
uses the SSL trust model (i.e. any member of the ‘Authenticode’
equivalent of the ‘SSL mafia’ can issue a code-signing certificate with
any signer name). It is possible to verify the fingerprint of the
certificate for the key which actually signed the program file, but
users are unlikely to do that.

We can't fix design flaws in the host operating system or desktop
environment from within Tor Browser Bundle. But we can display a small
splash screen the first time a user starts TBB, and allow the user to
select a more discreet startup indicator or none at all for future use.
