Rename blueprints: .mdwn → .md authored by intrigeri's avatar intrigeri
Rationale:

 - Right now:

   - These pages' Markdown will be rendered when browsing our
     repository in the GitLab web interface

   - The .md extension is more common nowadays: GitHub, GitLab, and various
     other major players have settled on it. Let's get used to it.

 - If we decide to migrate our blueprints to GitLab (#18079),
   this will be a necessary first step.

1. Download your emails or save this document to local storage: [[tails-keysigning.txt.gz]].
1. If you want, download the set of public keys: [[tails-keysigning.asc]].
1. Turn off all network connections.
1. Decompress that file:
gunzip tails-keysigning.txt.gz
1. Compute the SHA-256 sum:
gpg --print-md sha256 tails-keysigning.txt
1. Make sure it starts with the letter 'F'.
1. Wait for everybody to be ready.
1. We confirm the document SHA-256 sum together.
1. Search for your own fingerprint and your own user ids and
verify that they are indeed what they should be.
1. In the order of the document, we confirm the user id and fingerprint
information. Each participant physically present will, in turn stand up and
states:
- Their name
- That they have verified their fingerprints
- That they have verified their user ids
1. Other people in the room who know this person confirm the identity of this
participant.
1. If you trust what you hear, put an 'x' in the corresponding checkboxes in
your file.
1. At the end, sign the resulting document with your own key for
later verification.
gpg --clearsign tails-keysigning.txt
1. When back home, take your time to sign the keys after verifying that this
document has not been tampered with, ideally using
[caff](https://wiki.debian.org/caff).
