Once you have obtained the Qubes Master Signing Key,
you should verify the fingerprint of this key very carefully by obtaining
copies of the fingerprint from trustworthy independent sources and comparing
them to the downloaded key's fingerprint to ensure they match. Then set its
trust level to "ultimate" (oh, well), so that it can be used to automatically
verify all the keys signed by the Qubes Master Signing Key:
copies of the fingerprint from multiple independent sources and comparing
them to the downloaded key's fingerprint to ensure they match. Here are some
ideas:
* Use different search engines to search for the fingerprint.
* Use Tor to view and search for the fingerprint on various websites.
* Use various VPNs and proxy servers.
* Use different Wi-Fi networks (work, school, internet cafe, etc.).
* Ask people to post the fingerprint in various forums and chat rooms.
* Check against PDFs and photographs in which the fingerprint appears
(e.g., slides from a talk or on a T-shirt).
* Repeat all of the above from different computers and devices.
In addition, some operating systems have built-in keyrings containing keys
capable of validating the Qubes Master Signing Key. For example, if you have
a Debian system, then your debian-keyring may already contain the necessary
keys.
Once you're confident that you have the legitimate Qubes Master Signing Key,
set its trust level to "ultimate" (oh, well), so that it can be used to
automatically verify all the keys signed by the Qubes Master Signing Key:
