1ebb25608fa10737ea27abd4e0481707ccd45581Tinderbox User verifies that the DNSSEC keys for a given zone or a set of zones
1ebb25608fa10737ea27abd4e0481707ccd45581Tinderbox User have timing metadata set properly to ensure no future lapses in DNSSEC
1ebb25608fa10737ea27abd4e0481707ccd45581Tinderbox User If <code class="option">zone</code> is specified, then keys found in
1ebb25608fa10737ea27abd4e0481707ccd45581Tinderbox User the key repository matching that zone are scanned, and an ordered
1ebb25608fa10737ea27abd4e0481707ccd45581Tinderbox User list is generated of the events scheduled for that key (i.e.,
1ebb25608fa10737ea27abd4e0481707ccd45581Tinderbox User publication, activation, inactivation, deletion). The list of
1ebb25608fa10737ea27abd4e0481707ccd45581Tinderbox User events is walked in order of occurrence. Warnings are generated
1ebb25608fa10737ea27abd4e0481707ccd45581Tinderbox User if any event is scheduled which could cause the zone to enter a
1ebb25608fa10737ea27abd4e0481707ccd45581Tinderbox User state in which validation failures might occur: for example, if
1ebb25608fa10737ea27abd4e0481707ccd45581Tinderbox User the number of published or active keys for a given algorithm drops
1ebb25608fa10737ea27abd4e0481707ccd45581Tinderbox User to zero, or if a key is deleted from the zone too soon after a new
1ebb25608fa10737ea27abd4e0481707ccd45581Tinderbox User key is rolled, and cached data signed by the prior key has not had
1ebb25608fa10737ea27abd4e0481707ccd45581Tinderbox User time to expire from resolver caches.
1ebb25608fa10737ea27abd4e0481707ccd45581Tinderbox User If <code class="option">zone</code> is not specified, then all keys in the
1ebb25608fa10737ea27abd4e0481707ccd45581Tinderbox User key repository will be scanned, and all zones for which there are
1ebb25608fa10737ea27abd4e0481707ccd45581Tinderbox User keys will be analyzed. (Note: This method of reporting is only
1ebb25608fa10737ea27abd4e0481707ccd45581Tinderbox User accurate if all the zones that have keys in a given repository
1ebb25608fa10737ea27abd4e0481707ccd45581Tinderbox User share the same TTL parameters.)

1ebb25608fa10737ea27abd4e0481707ccd45581Tinderbox User before that key can be purged from the DNSKEY RRset. If that
