4a2f0f0be43dfd4c1b490cbf3cc48b6ba6084b1cAllan Foster verifies that the DNSSEC keys for a given zone or a set of zones
4a2f0f0be43dfd4c1b490cbf3cc48b6ba6084b1cAllan Foster have timing metadata set properly to ensure no future lapses in DNSSEC
4a2f0f0be43dfd4c1b490cbf3cc48b6ba6084b1cAllan Foster If <code class="option">zone</code> is specified, then keys found in
4a2f0f0be43dfd4c1b490cbf3cc48b6ba6084b1cAllan Foster the key repository matching that zone are scanned, and an ordered
4a2f0f0be43dfd4c1b490cbf3cc48b6ba6084b1cAllan Foster list is generated of the events scheduled for that key (i.e.,
4a2f0f0be43dfd4c1b490cbf3cc48b6ba6084b1cAllan Foster publication, activation, inactivation, deletion). The list of
4a2f0f0be43dfd4c1b490cbf3cc48b6ba6084b1cAllan Foster events is walked in order of occurrence. Warnings are generated
4a2f0f0be43dfd4c1b490cbf3cc48b6ba6084b1cAllan Foster if any event is scheduled which could cause the zone to enter a
4a2f0f0be43dfd4c1b490cbf3cc48b6ba6084b1cAllan Foster state in which validation failures might occur: for example, if
4a2f0f0be43dfd4c1b490cbf3cc48b6ba6084b1cAllan Foster the number of published or active keys for a given algorithm drops
4a2f0f0be43dfd4c1b490cbf3cc48b6ba6084b1cAllan Foster to zero, or if a key is deleted from the zone too soon after a new
4a2f0f0be43dfd4c1b490cbf3cc48b6ba6084b1cAllan Foster key is rolled, and cached data signed by the prior key has not had
4a2f0f0be43dfd4c1b490cbf3cc48b6ba6084b1cAllan Foster time to expire from resolver caches.
4a2f0f0be43dfd4c1b490cbf3cc48b6ba6084b1cAllan Foster If <code class="option">zone</code> is not specified, then all keys in the
4a2f0f0be43dfd4c1b490cbf3cc48b6ba6084b1cAllan Foster key repository will be scanned, and all zones for which there are
4a2f0f0be43dfd4c1b490cbf3cc48b6ba6084b1cAllan Foster keys will be analyzed. (Note: This method of reporting is only
4a2f0f0be43dfd4c1b490cbf3cc48b6ba6084b1cAllan Foster accurate if all the zones that have keys in a given repository
4a2f0f0be43dfd4c1b490cbf3cc48b6ba6084b1cAllan Foster share the same TTL parameters.)

4a2f0f0be43dfd4c1b490cbf3cc48b6ba6084b1cAllan Foster Sets the directory in which keys can be found. Defaults to the
4a2f0f0be43dfd4c1b490cbf3cc48b6ba6084b1cAllan Foster current working directory.

4a2f0f0be43dfd4c1b490cbf3cc48b6ba6084b1cAllan Foster If a <code class="option">file</code> is specified, then the zone is
4a2f0f0be43dfd4c1b490cbf3cc48b6ba6084b1cAllan Foster read from that file; the largest TTL and the DNSKEY TTL are
4a2f0f0be43dfd4c1b490cbf3cc48b6ba6084b1cAllan Foster determined directly from the zone data, and the
4a2f0f0be43dfd4c1b490cbf3cc48b6ba6084b1cAllan Foster <code class="option">-m</code> and <code class="option">-d</code> options do
4a2f0f0be43dfd4c1b490cbf3cc48b6ba6084b1cAllan Foster not need to be specified on the command line.
4a2f0f0be43dfd4c1b490cbf3cc48b6ba6084b1cAllan Foster<dt><span class="term">-l <em class="replaceable"><code>duration</code></em></span></dt>
4a2f0f0be43dfd4c1b490cbf3cc48b6ba6084b1cAllan Foster The length of time to check for DNSSEC coverage. Key events
4a2f0f0be43dfd4c1b490cbf3cc48b6ba6084b1cAllan Foster scheduled further into the future than <code class="option">duration</code>
4a2f0f0be43dfd4c1b490cbf3cc48b6ba6084b1cAllan Foster will be ignored, and assumed to be correct.
4a2f0f0be43dfd4c1b490cbf3cc48b6ba6084b1cAllan Foster The value of <code class="option">duration</code> can be set in seconds,
4a2f0f0be43dfd4c1b490cbf3cc48b6ba6084b1cAllan Foster or in larger units of time by adding a suffix: 'mi' for minutes,
4a2f0f0be43dfd4c1b490cbf3cc48b6ba6084b1cAllan Foster 'h' for hours, 'd' for days, 'w' for weeks, 'mo' for months,
4a2f0f0be43dfd4c1b490cbf3cc48b6ba6084b1cAllan Foster 'y' for years.
4a2f0f0be43dfd4c1b490cbf3cc48b6ba6084b1cAllan Foster<dt><span class="term">-m <em class="replaceable"><code>maximum TTL</code></em></span></dt>
4a2f0f0be43dfd4c1b490cbf3cc48b6ba6084b1cAllan Foster Sets the value to be used as the maximum TTL for the zone or
4a2f0f0be43dfd4c1b490cbf3cc48b6ba6084b1cAllan Foster zones being analyzed when determining whether there is a
4a2f0f0be43dfd4c1b490cbf3cc48b6ba6084b1cAllan Foster possibility of validation failure. When a zone-signing key is
4a2f0f0be43dfd4c1b490cbf3cc48b6ba6084b1cAllan Foster deactivated, there must be enough time for the record in the
4a2f0f0be43dfd4c1b490cbf3cc48b6ba6084b1cAllan Foster zone with the longest TTL to have expired from resolver caches
4a2f0f0be43dfd4c1b490cbf3cc48b6ba6084b1cAllan Foster before that key can be purged from the DNSKEY RRset. If that
4a2f0f0be43dfd4c1b490cbf3cc48b6ba6084b1cAllan Foster condition does not apply, a warning will be generated.
4a2f0f0be43dfd4c1b490cbf3cc48b6ba6084b1cAllan Foster The length of the TTL can be set in seconds, or in larger units
4a2f0f0be43dfd4c1b490cbf3cc48b6ba6084b1cAllan Foster of time by adding a suffix: 'mi' for minutes, 'h' for hours,
4a2f0f0be43dfd4c1b490cbf3cc48b6ba6084b1cAllan Foster 'd' for days, 'w' for weeks, 'mo' for months, 'y' for years.
4a2f0f0be43dfd4c1b490cbf3cc48b6ba6084b1cAllan Foster This option is mandatory unless the <code class="option">-f</code> has
4a2f0f0be43dfd4c1b490cbf3cc48b6ba6084b1cAllan Foster been used to specify a zone file. (If <code class="option">-f</code> has
4a2f0f0be43dfd4c1b490cbf3cc48b6ba6084b1cAllan Foster been specified, this option may still be used; it will overrde
4a2f0f0be43dfd4c1b490cbf3cc48b6ba6084b1cAllan Foster the value found in the file.)
4a2f0f0be43dfd4c1b490cbf3cc48b6ba6084b1cAllan Foster<dt><span class="term">-d <em class="replaceable"><code>DNSKEY TTL</code></em></span></dt>
4a2f0f0be43dfd4c1b490cbf3cc48b6ba6084b1cAllan Foster Sets the value to be used as the DNSKEY TTL for the zone or
