Description
~~~~~~~~~~~

``dnssec-importkey`` reads a public DNSKEY record and generates a pair
of .key/.private files. The DNSKEY record may be read from an
existing .key file, in which case a corresponding .private file is
generated, or it may be read from any other file or from the standard
input, in which case both .key and .private files are generated.

The newly created .private file does *not* contain private key data, and
cannot be used for signing. However, having a .private file makes it
possible to set publication (``-P``) and deletion (``-D``) times for the
key, which means the public key can be added to and removed from the
DNSKEY RRset on schedule even if the true private key is stored offline.

Options
~~~~~~~

``-f filename``
   This option indicates the zone file mode. Instead of a public keyfile name, the argument is the
   DNS domain name of a zone master file, which can be read from
   ``filename``. If the domain name is the same as ``filename``, then it may be
   omitted.

   If ``filename`` is set to ``"-"``, then the zone data is read from the
   standard input.

``-K directory``
   This option sets the directory in which the key files are to reside.

``-L ttl``
   This option sets the default TTL to use for this key when it is converted into a
   DNSKEY RR. This is the TTL used when the key is imported into a zone,
   unless there was already a DNSKEY RRset in
   place, in which case the existing TTL takes precedence. Setting the default TTL to ``0`` or ``none``
   removes it from the key.

``-h``
   This option emits a usage message and exits.

``-v level``
   This option sets the debugging level.

``-V``
   This option prints version information.

Timing Options
~~~~~~~~~~~~~~

Dates can be expressed in the format YYYYMMDD or YYYYMMDDHHMMSS. If the
argument begins with a ``+`` or ``-``, it is interpreted as an offset from
the present time. For convenience, if such an offset is followed by one
of the suffixes ``y``, ``mo``, ``w``, ``d``, ``h``, or ``mi``, then the offset is
computed in years (defined as 365 24-hour days, ignoring leap years),
months (defined as 30 24-hour days), weeks, days, hours, or minutes,
respectively. Without a suffix, the offset is computed in seconds. To
explicitly prevent a date from being set, use ``none`` or ``never``.

``-P date/offset``
   This option sets the date on which a key is to be published to the zone. After
   that date, the key is included in the zone but is not used
   to sign it.

``-P sync date/offset``
   This option sets the date on which CDS and CDNSKEY records that match this key
   are to be published to the zone.

``-D date/offset``
   This option sets the date on which the key is to be deleted. After that date, the
   key is no longer included in the zone. (However, it may remain in the key
   repository.)

``-D sync date/offset``
   This option sets the date on which the CDS and CDNSKEY records that match this
   key are to be deleted.

Files
~~~~~

A keyfile can be designed by the key identification ``Knnnn.+aaa+iiiii``
or the full file name ``Knnnn.+aaa+iiiii.key``, as generated by
``dnssec-keygen``.
