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

If a file is specified, then the zone is read from that file; the largest TTL and the DNSKEY TTL are determined directly from the zone data, and the -m and -d options do not need to be specified on the command line.

The length of time to check for DNSSEC coverage. Key events scheduled further into the future than duration will be ignored, and assumed to be correct.

The value of duration can be set in seconds, or in larger units of time by adding a suffix: mi for minutes, h for hours, d for days, w for weeks, mo for months, y for years.

Sets the value to be used as the maximum TTL for the zone or zones being analyzed when determining whether there is a possibility of validation failure. When a zone-signing key is deactivated, there must be enough time for the record in the zone with the longest TTL to have expired from resolver caches before that key can be purged from the DNSKEY RRset. If that condition does not apply, a warning will be generated.

The length of the TTL can be set in seconds, or in larger units of time by adding a suffix: mi for minutes, h for hours, d for days, w for weeks, mo for months, y for years.

This option is not necessary if the -f has been used to specify a zone file. If -f has been specified, this option may still be used; it will override the value found in the file.

If this option is not used and the maximum TTL cannot be retrieved from a zone file, a warning is generated and a default value of 1 week is used.

Sets the value to be used as the DNSKEY TTL for the zone or zones being analyzed when determining whether there is a possibility of validation failure. When a key is rolled (that is, replaced with a new key), there must be enough time for the old DNSKEY RRset to have expired from resolver caches before the new key is activated and begins generating signatures. If that condition does not apply, a warning will be generated.

The length of the TTL can be set in seconds, or in larger units of time by adding a suffix: mi for minutes, h for hours, d for days, w for weeks, mo for months, y for years.

This option is not necessary if -f has been used to specify a zone file from which the TTL of the DNSKEY RRset can be read, or if a default key TTL was set using ith the -L to dnssec-keygen. If either of those is true, this option may still be used; it will override the values found in the zone file or the key file.

If this option is not used and the key TTL cannot be retrieved from the zone file or the key file, then a warning is generated and a default value of 1 day is used.

Sets the value to be used as the resign interval for the zone or zones being analyzed when determining whether there is a possibility of validation failure. This value defaults to 22.5 days, which is also the default in named. However, if it has been changed by the sig-validity-interval option in named.conf, then it should also be changed here.

The length of the interval can be set in seconds, or in larger units of time by adding a suffix: mi for minutes, h for hours, d for days, w for weeks, mo for months, y for years.

Only check KSK coverage; ignore ZSK events. Cannot be used with -z.

Specifies a path to a named-compilezone binary. Used for testing.
