+Keyring handling
+================
+
+As a general rule, keyring requests arrive via Debian's RT, and we
+usually ask people to open a ticket so it is kept as a reference. 
+
+When you are working with a request, claim the ticket and set it to
+the "open" state from RT's web interface.
+
+Once it is done, send a message (either reply to RT's message on the
+mail or via RT's web interface - taking care to use "reply" and not
+"comment", to make it visible to the submitter) telling the change is
+done in the working tree, and explaining we might take some time to
+publish the changes - Something like this:
+
+    The changes you have requested have been pushed to our working
+    tree, and will be included in the next keyring push. Please be
+    patient - We batch several requests together, and tend to do
+    approximately one push per month.
+
+The operations on keyring are on a separate file each, for ease of
+reference. They are:
+
+Adding a DD key      - keyring/adding_dd.txt
+Removing a DD key    - keyring/removing_dd.txt
+Updating a DD key    - keyring/updating_dd.txt
+Adding a DM key      - keyring/adding_dm.txt
+Promoting a DM to DD - keyring/dm_to_dd.txt

+Git working tree
+----------------
+
+Keyring work is coordinated in the Git tree living in
+/srv/keyring.debian.org/master-keyring.git/ at keyring.debian.org
+(which is an alias to kaufmann.debian.org). You need to have an
+account on kaufmann to get access to the working tree. The URL for the
+Git repository is:
+
+  ssh://kaufmann.debian.org/srv/keyring.debian.org/master-keyring.git/
+
+Note that, before March 2014, we used to work on a Bazaar tree. When
+the tree was imported over to Git, the only bit of lost information
+were the commit signatures. The Bazaar tree up to that point (left at
+commit #1297) is still available in Kaufmann, at
+/srv/keyring.debian.org/master-keyring/ (probably we should replace it
+to avoid confusions!).
+
+Public tree copy
+----------------
+
+There is a public copy of the tree we push to whenever we push the
+updates; it is available at Debian's Git server:
+
+  https://salsa.debian.org/debian-keyring/keyring.git
+
+This tree can also be browsed online at:
+
+  http://salsa.debian.org/debian-keyring/keyring
+
+So, when you push a new revision, do:
+
+  $ git push git@salsa.debian.org:debian-keyring/keyring.git master
+
+Signing commits
+---------------
+
+All commits should be GPG-signed. To do so, specify your signing key
+to Git, like:
+
+  $ git config user.signingkey 0x0000DEAD0000BEEF
+
+And remember to always specify the '-S' switch when committing!
+
+Note that if you use debcommit, you can ask it to always sign commits
+by either setting its DEBCOMMIT_SIGN_COMMITS configuration variable or
+by specifying --sign-commit in the command line.
+
+** Note: A nice Git hook can be of use here to remind us if we're
+   missing -S
+
+Parsing the Git changelog
+-------------------------
+
+When pushing a new keyring revision, you can use
+./script/parse-git-changelog to automate several steps. Pipe it the
+changelog since the last uploaded revision (remember to tag it!):
+
+$ git log 2014.11.19.. | scripts/parse-git-changelog
+
+It will create three files: rt-update, ldap-update and dak-update. For
+the two first ones, look in the respective cheatsheets; for the
+dak-update; refer to Ansgar Burchardt's message (Message-ID:
+<87tx2uvcti.fsf@deep-thought.43-1.org>):
+
+    Hi,
+
+    as DM permissions are bound to specific keys they need to be updated if
+    a DM changes his key. Currently I do so from time to time (usually when
+    somebody has problems uploading packages), but it would be nice if you
+    could tell dak that keys changed.
+    
+    To do so, please wait until the new keys have been installed and then
+    upload a <user>-<YYYYMMDD>-<HHMM>.dak-commands via ftp to ftp-master. It
+    should look like the following:
+

+    replies are sent to the primary UID of the key that was used to sign the

+We can now directly update LDAP records - That means that key updates
+can now be handled directly by us. There are several tools that can be
+used for this purpose - I'm using ud-info. For this, I have to use the
+Debian password (and given I dislike passwords, I always regenerate it
+by following http://db.debian.org/password.html and throwing it away).
+
+keyring-maint has access to updating DD keys, but _not_ to change
+their account status - That is, creating new DD accounts and retiring
+DDs requires reassigning the tickets to DSA.
+
+To edit a DD's entry, we specify his username - In this case, I will

+shown), and a short menu of actions:

+Request Tracker (rt.debian.org)
+-------------------------------
+
+ [ Note: This file is basically a copy of Jonathan's "brain dump"
+   series, where he explained the workings of keyring to Gunnar, who
+   is writing this paragraph in third person. Hopefully, this will
+   reach somebody else in the future! ;-) ]
+
+ [ Note much later on: The text following here describes interaction
+   using the Web interface. It is valid, but we have found much easier
+   to use the `rt' command in the `rt4-clients' package.
+
+   The parse-git-changelog script will output a script that uses rhis
+   command and greatly simplifies closing and reasigning tickets when
+   many changes are involved.]
+
+
+So, RT. Why not just bugs.debian.org? I think the original rationale
+was that there's the potential for sensitive information to need to be
+tracked, in a similar manner to DSA. For example last week we had a DD
+with a potentially compromised key; wise to keep that information
+limited until the key was removed from the active keyring.
+
+I don't know if you've used Debian RT at all; it lives at:
+
+http://rt.debian.org/
+
+and you can get read only access to the public bits with the username
+guest and password readonly
+
+That will get you access to the "Keyring" queue, which is the public
+one. The one you can't see is "Keyring - Incoming" which currently has
+a bunch of key replacement requests sitting in it. These aren't
+particularly sensitive I guess, but I prefer to keep them private
+until implemented. Most of them are just waiting for post DebConf
+signatures to trickle in to help limit damage to the WoT.
+
+The Keyring queue at present has a couple of new DDs (which I'll sort
+out within the next week) and some older key replacements. However if
+you look through the closed tickets in that queue you should be able
+to match them up to the Git commits - anything that came from an RT
+ticket should have the ticket number in the changelog (occasionally
+this doesn't happen, but it's a mistake). Nothing closed should end up
+in the "Keyring - Incoming" queue; it all gets moved to Keyring at the
+point it's closed, so everything is eventually public.
+
+Users tend to create new tickets by emailing keyring@rt.debian.org -
+they need to put "Debian RT" in the subject to get it past the rt.d.o
+spam stuff and hopefully they also put something helpful in there as
+well, but often they don't. It's easy enough to retitle in RT. Tickets
+that come in via this interface end up in the "Keyring - Incoming"
+queue.
+
+One major problem with RT to note is that it mangles PGP/MIME
+signatures, so everything has to be done with inline signatures. I've
+also seen some mangling of those but only on mail from Joerg so I'm
+not sure if it's him or RT that's the problem.
+
+The other use for RT is asking DSA to make updates to LDAP; every user
+has an associated fingerprint (or multiple fingerprints, but at
+present that's only users with v3 + v4 keys). For "New DD" tickets
+that came from DAM I just reassign them to DSA once I've added the key
+and then they can deal with the account creation (the key needs added
+before the account so the initial password can be sent out
+encrypted). When I remove keys or do key replacements I just create a
+new ticket (via signed mail to admin@rt.debian.org); usually I've
+batched up a bunch of changes so I send one mail with details of all
+the removals/changes and reasoning. See RT #1667, #1664 or #1520 for
+examples of these mails.
+
+   *** Note - As of August 2010, we can now do the LDAP updates
+       ourselves. We should update this text with the pertinent
+       information / procedure.

+Pulling changes from the HKP server
+===================================
+
+We run a HKP (HTTP Keyserver Protocol) keyserver to allow for public
+querying on Debian keys and to allow DDs and DMs to update their keys,
+i.e., sending more signatures. Updating the keyrings from this HKP
+server is "pulling" HKP changes.
+
+There's a script call pull-updates that takes a keyring and a keyring
+dir, explodes the keyring and looks for keys that have changed, then
+calls update-key for each of them. This is a bit of a labour intensive
+task, but it does mean we don't automatically allow things like adding
+a new UID that's complete nonsense. I have some local patches to make
+it a bit easier in terms of automatically generating an update.log
+which is the same format as in the changelog of what was altered; I'll
+commit them at some point soon.
+
+So, to import the HKP updates:

+Removing a DD key
+=================
+
+Some more verbosity would not hurt... Anyway, little is better than none.
+
+- Emeritus
+
+| # Deal with RT #142
+| # Straightforward resignation, debian-private mail confirmed,
+| # move key to emeritus
+| ./script/move-key 0xFCF6DD4539CCF0C7 emeritus-keyring-gpg/
+
+The move-key script will move the key from any of the active keyrings
+it is currently located on.
+
+If the key is not moved due to the maintainer explicitly resigning
+(i.e. expelled, deceased, MIA), the key should be removed entirely.
+
+Changelog entry:
+------------------------------------------------------------
+  * Move 0xFCF6DD4539CCF0C7 (Akira TAGOH) to emeritus (RT #142)
+------------------------------------------------------------
+
+Commit message:
+------------------------------------------------------------
+Move 0xFCF6DD4539CCF0C7 (Akira TAGOH) to emeritus (RT #142)
+  
+    Akira has retired from Debian.
+    Message-Id: <20070731.194218.174801666.tagoh@debian.org>
+------------------------------------------------------------
+
+- MIA
+
+Eventually, the MIA team comes up with a list of people not answering
+to the WAT ping (Where Are They?). The main difference for us is that,
+instead of moving the key to emeritus-keyring-gpg, it is removed entirely.

+Updating a DD key
+=================
+
+- Key updates should be for a reason (i.e. lost control of earlier
+  key, or moving to stronger key).
+
+- Request must include:
+  - Old key (full fingerprint)
+  - New key (full fingerprint)
+  - Inline signature with OLD key
+
+- New key must be signed by at least two DDs (and more if possible);
+  if the old key is particularly well connected, we have requested the
+  person to get more signatures in order to avoid weakening the
+  overall web of trust. The new key must also be signed with the old
+  one (except in cases, say, where the old one was lost).
+
+- Procedure
+
+  I am following the request for Giovanni Mascellani (RT #2473). Of
+  course, replace keys with adequate values. As you can see, this
+  request mentioned only the key IDs, so full fingerprint was
+  requested. 
+
+      # Before anything else, retrieve both keys, to be able to do the
+      # following checks
+  $ gpg --keyserver $KEYSERVER --recv-key \
+      1EB63D43E2014DDF67BD003FFCB0BB5C5F1FBF70 \

+  - Helper script
+
+    We have a script called "replace-key". When called, it takes care to
+    do all of the steps described from here until the commit step.
+
+    You should call it using both keys' long (64 bit) keyids:
+
+    $ ./script/replace-key FCB0BB5C5F1FBF70 9EDCC991D9AB457E
+
+
+  $ gpg --export D9AB457E > /tmp/key
+      # DD keys (past and present), names and identities are kept in
+      # the plaintext file 'keyids' - Confirm and get the requester's
+      # Debian account name in case it's not listed as one of the
+      # identities 
+
+  $ grep 5F1FBF70 keyids 
+  0xFCB0BB5C5F1FBF70 Giovanni Mascellani <gio>
+      # Old keys are removed from the repository.
+
+  $ git rm debian-keyring-gpg/0xFCB0BB5C5F1FBF70
+  rm 'debian-keyring-gpg/0xFCB0BB5C5F1FBF70'
+
+  $ ./scripts/add-key /tmp/key debian-keyring-gpg/
+      # A screen listing all of the requester's signatures which are
+      # in the Debian keyring appears. At very least, two DD should
+      # have signed his key, unless specific reasons
+      # (i.e. geographical) have been already discussed. Take note of
+      # the respective key IDs. If they are too many, just note the
+      # first four or five, in this case: F2C423BC 33FC40A4.
+      # Also take note that the old key (5F1FBF70) has also signed
+      # it. 
+  Are you sure you want to update this key? (y/n)

+  adding debian-keyring-gpg/0x9EDCC991D9AB457E

+
+- Git commit
+
+  In order for the parse-git-changelog script to work, we adhere to
+  machine-parsable information in the changelog. If you used the
+  replace-key script, you will find it creates a git-commit-template
+  file. It just needs you to fill in the Debian user IDs for the
+  New-key-certified-by field.
