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-api#get_matrixkeyv2serverkeyid)
|
|
or [POST
|
|
/\_matrix/key/v2/query](/server-server-api#post_matrixkeyv2query)
|
|
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.
|
|
|
|
Servers MUST use the lesser of `valid_until_ts` and 7 days into the
|
|
future when determining if a key is valid. This is to avoid a situation
|
|
where an attacker publishes a key which is valid for a significant
|
|
amount of time without a way for the homeserver owner to revoke it.
