Room Version 5
|
||
|
|
==============
|
||
|
|
|
||
|
|
This room version builds on `version 4 <v4.html>`_, enforcing signing key validity
|
||
|
|
periods for events.

Client considerations
|
||
|
|
---------------------
|
||
|
|
|
||
|
|
There are no specific requirements for clients in this room version. Clients should
|
||
|
|
be aware of event ID changes in `room version 4 <v4.html>`_, however.
|
||
|
|
|
||
|
|
|
||
|
|
Server implementation components
|
||
|
|
--------------------------------
|
||
|
|
|
||
|
|
.. WARNING::
|
||
|
|
The information contained in this section is strictly for server implementors.
|
||
|
|
Applications which use the Client-Server API are generally unaffected by the
|
||
|
|
intricacies contained here. The section above regarding client considerations
|
||
|
|
is the resource that Client-Server API use cases should reference.
|
||
|
|
|
||
|
|
|
||
|
|
Room version 5 uses the same algorithms defined in `room version 4 <v4.html>`_, ensuring
|
||
|
|
that signing key validity is respected.
|
||
|
|
|
||
|
|
Signing key validity period
|
||
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||
|
|
|
||
|
|
When validating event signatures, servers MUST enforce the ``valid_until_ts`` property
|
||
|
|
from a key request is at least as large as the ``origin_server_ts`` for the event being
|
||
|
|
validated. Servers missing a copy of the signing key MUST try to obtain one via the
|
||
|
|
`GET /_matrix/key/v2/server <../server_server/r0.1.1.html#get-matrix-key-v2-server-keyid>`_
|
||
|
|
or `POST /_matrix/key/v2/query <../server_server/r0.1.1.html#post-matrix-key-v2-query>`_
|
||
|
|
APIs. When using the ``/query`` endpoint, servers MUST set the ``minimum_valid_until_ts``
|
||
|
|
property to prompt the notary server to attempt to refresh the key if appropriate.
