A server may have multiple keys active at a given time. A server may have any
|
|
|
|
|
|
|
|
number of old keys. It is recommended that servers return a single JSON
|
|
|
|
|
|
|
|
response listing all of its keys whenever any ``key_id`` is requested to reduce
|
|
|
|
|
|
|
|
the number of round trips needed to discover the relevant keys for a server.
|
|
|
|
|
|
|
|
However a server may return different responses for a different ``key_id``.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
The ``tls_certificates`` field contains a list of hashes of the X.509 TLS
|
|
|
|
|
|
|
|
certificates currently used by the server. The list must include SHA-256 hashes
|
|
|
|
|
|
|
|
for every certificate currently in use by the server. These fingerprints are
|
|
|
|
|
|
|
|
valid until the millisecond POSIX timestamp in ``valid_until_ts``.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
The ``verify_keys`` can be used to sign requests and events made by the server
|
|
|
|
|
|
|
|
until the millisecond POSIX timestamp in ``valid_until_ts``. If a homeserver
|
|
|
|
|
|
|
|
receives an event with a ``origin_server_ts`` after the ``valid_until_ts`` then
|
|
|
|
|
|
|
|
it should request that ``key_id`` for the originating server to check whether
|
|
|
|
|
|
|
|
the key has expired.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
The ``old_verify_keys`` can be used to sign events with an ``origin_server_ts``
|
|
|
|
|
|
|
|
before the ``expired_ts``. The ``expired_ts`` is a millisecond POSIX timestamp
|
|
|
|
|
|
|
|
of when the originating server stopped using that key.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Intermediate notary servers should cache a response for half of its remaining
|
|
|
|
|
|
|
|
lifetime to avoid serving a stale response. Originating servers should avoid
|
|
|
|
|
|
|
|
returning responses that expire in less than an hour to avoid repeated requests
|
|
|
|
|
|
|
|
for a certificate that is about to expire. Requesting servers should limit how
|
|
|
|
|
|
|
|
frequently they query for certificates to avoid flooding a server with
|
|
|
|
|
|
|
|
requests.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
If a server goes offline intermediate notary servers should continue to return
|
|
|
|
|
|
|
|
the last response they received from that server so that the signatures of old
|
|
|
|
|
|
|
|
events sent by that server can still be checked.

Servers may offer a query API ``/_matrix/key/v2/query/`` for getting the keys
|
|
|
|
|
|
|
|
for another server. This API can be used to GET a list of JSON objects for a
|
|
|
|
|
|
|
|
given server or to POST a bulk query for a number of keys from a number of
|
|
|
|
|
|
|
|
servers. Either way the response is a list of JSON objects containing the
|
|
|
|
|
|
|
|
JSON published by the server under ``/_matrix/key/v2/server/`` signed by
|
|
|
|
|
|
|
|
both the originating server and by this server.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
The ``minimum_valid_until_ts`` is a millisecond POSIX timestamp indicating
|
|
|
|
|
|
|
|
when the returned certificate will need to be valid until to be useful to the
|
|
|
|
|
|
|
|
requesting server. This can be set using the maximum ``origin_server_ts`` of
|
|
|
|
|
|
|
|
a batch of events that a requesting server is trying to validate. This allows
|
|
|
|
|
|
|
|
an intermediate notary server to give a prompt cached response even if the
|
|
|
|
|
|
|
|
originating server is offline.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
This API can return keys for servers that are offline by using cached responses
|
|
|
|
|
|
|
|
taken from when the server was online. Keys can be queried from multiple
|
|
|
|
|
|
|
|
servers to mitigate against DNS spoofing.

In some circumstances, a homeserver may be missing a particular event or information
|
|
|
|
|
|
|
|
about the room which cannot be easily determined from backfilling. These APIs provide
|
|
|
|
|
|
|
|
homeservers with the option of getting events and the state of the room at a given
|
|
|
|
|
|
|
|
point in the timeline.

Leaving Rooms (Rejecting Invites)
|
|
|
|

|
|
---------------------------------
|
|
|
|
|

|

|
|

|
|
|
Normally homeservers can send appropriate ``m.room.member`` events to have users
|
|
|
|
|
|
|
|
leave the room, or to reject local invites. Remote invites from other homeservers
|
|
|
|
|
|
|
|
do not involve the server in the graph and therefore need another approach to
|
|
|
|
|
|
|
|
reject the invite. Joining the room and promptly leaving is not recommended as
|
|
|
|
|
|
|
|
clients and servers will interpret that as accepting the invite, then leaving the
|
|
|
|
|
|
|
|
room rather than rejecting the invite.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Similar to the `Joining Rooms`_ handshake, the server which wishes to leave the
|
|
|
|
|
|
|
|
room starts with sending a ``/make_leave`` request to a resident server. In the
|
|
|
|
|
|
|
|
case of rejecting invites, the resident server may be the server which sent the
|
|
|
|
|
|
|
|
invite. After receiving a template event from ``/make_leave``, the leaving server
|
|
|
|
|
|
|
|
signs the event and replaces the ``event_id`` with it's own. This is then sent to
|
|
|
|
|
|
|
|
the resident server via ``/send_leave``. The resident server will then send the
|
|
|
|
|
|
|
|
event to other servers in the room.
