Previously, we only fetched keys once, only requesting them again if we have any missing, allowing for ancient keys to be used to sign PDUs and transactions Now we refresh keys that either have or are about to expire, preventing attacks that make use of leaked private keys of a homeserver We also ensure that when validating PDUs or transactions, that they are valid at the origin_server_ts or time of us receiving the transaction respectfully As to not break event authorization for old rooms, we need to keep old keys around We move verify_keys which we no longer see in direct requests to the origin to old_verify_keys We keep old_verify_keys indefinitely as mentioned above, as to not break event authorization (at least until a future MSC addresses this) |
