    <para><command>dnssec-importkey</command>
      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
      will be generated, or it may be read from any other file or
      from the standard input, in which case both .key and .private
      files will be generated.
    </para>
    <para>
      The newly-created .private file does <emphasis>not</emphasis>
      contain private key data, and cannot be used for signing.
      However, having a .private file makes it possible to set
      publication (<option>-P</option>) and deletion
      (<option>-D</option>) 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.

      <varlistentry>
	<term>-f <replaceable class="parameter">filename</replaceable></term>
	<listitem>
	  <para>
	    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 <option>file</option>.  If the domain name is the same as
	    <option>file</option>, then it may be omitted.
	  </para>
	  <para>
	    If <option>file</option> is set to <literal>"-"</literal>, then
	    the zone data is read from the standard input.
	  </para>
	</listitem>
      </varlistentry>

      <varlistentry>
	<term>-K <replaceable class="parameter">directory</replaceable></term>
	<listitem>
	  <para>
	    Sets the directory in which the key files are to reside.

      </varlistentry>

      <varlistentry>
	<term>-L <replaceable class="parameter">ttl</replaceable></term>
	<listitem>
	  <para>
	    Sets the default TTL to use for this key when it is converted
	    into a DNSKEY RR.  If the key is imported into a zone,
	    this is the TTL that will be used for it, unless there was
	    already a DNSKEY RRset in place, in which case the existing TTL
	    would take precedence.  Setting the default TTL to
	    <literal>0</literal> or <literal>none</literal> removes it.
	  </para>

    <para>
      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'.
    </para>

    <variablelist>
      <varlistentry>
	<term>-P <replaceable class="parameter">date/offset</replaceable></term>
	<listitem>
	  <para>
	    Sets the date on which a key is to be published to the zone.
	    After that date, the key will be included in the zone but will
	    not be used to sign it.
	  </para>
	</listitem>
      </varlistentry>

      <varlistentry>
	<term>-P sync <replaceable class="parameter">date/offset</replaceable></term>
	<listitem>
	  <para>
	    Sets the date on which CDS and CDNSKEY records that match this
	    key are to be published to the zone.
	  </para>
	</listitem>
      </varlistentry>

      <varlistentry>
	<term>-D <replaceable class="parameter">date/offset</replaceable></term>
	<listitem>
	  <para>
	    Sets the date on which the key is to be deleted.  After that
	    date, the key will no longer be included in the zone.  (It
	    may remain in the key repository, however.)
	  </para>
