60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein verifies that the DNSSEC keys for a given zone or a set of zones
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein have timing metadata set properly to ensure no future lapses in DNSSEC
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein If <code class="option">zone</code> is specified, then keys found in
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein the key repository matching that zone are scanned, and an ordered
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein list is generated of the events scheduled for that key (i.e.,
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein publication, activation, inactivation, deletion). The list of
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein events is walked in order of occurrence. Warnings are generated
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein if any event is scheduled which could cause the zone to enter a
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein state in which validation failures might occur: for example, if
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein the number of published or active keys for a given algorithm drops
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein to zero, or if a key is deleted from the zone too soon after a new
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein key is rolled, and cached data signed by the prior key has not had
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein time to expire from resolver caches.
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein If <code class="option">zone</code> is not specified, then all keys in the
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein key repository will be scanned, and all zones for which there are
b05bdb520d83f7ecaad708fe305268c3420be01dMark Andrews keys will be analyzed. (Note: This method of reporting is only
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein accurate if all the zones that have keys in a given repository
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein share the same TTL parameters.)

5a4557e8de2951a2796676b5ec4b6a90caa5be14Mark Andrews deactivated, there must be enough time for the record in the

60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein before that key can be purged from the DNSKEY RRset. If that

60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein signatures. If that condition does not apply, a warning
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein will be generated.
