<p><span class="command"><strong>dnssec-importkey</strong></span>
reads a public DNSKEY record and generates a pair of
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.
</p>
<p>
The newly-created .private file does <span class="emphasis"><em>not</em></span>
contain private key data, and cannot be used for signing.
However, having a .private file makes it possible to set
publication (<code class="option">-P</code>) and deletion
(<code class="option">-D</code>) 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.

<div class="variablelist"><dl class="variablelist">
<dt><span class="term">-f <em class="replaceable"><code>filename</code></em></span></dt>
<dd>
<p>
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 <code class="option">file</code>. If the domain name is the same as
<code class="option">file</code>, then it may be omitted.
</p>
<p>
If <code class="option">file</code> is set to <code class="literal">"-"</code>, then
the zone data is read from the standard input.
</p>
</dd>
<dt><span class="term">-K <em class="replaceable"><code>directory</code></em></span></dt>
<dd>
<p>
Sets the directory in which the key files are to reside.
</p>
</dd>
<dt><span class="term">-L <em class="replaceable"><code>ttl</code></em></span></dt>
<dd>
<p>
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
<code class="literal">0</code> or <code class="literal">none</code> removes it.
</p>

<dd>
<p>
Sets the debugging level.

<a name="id-1.9"></a><h2>TIMING OPTIONS</h2>
<p>
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>
<div class="variablelist"><dl class="variablelist">
<dd>
<p>
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.
</p>
</dd>
<dd>
<p>
Sets the date on which CDS and CDNSKEY records that match this
key are to be published to the zone.
</p>
</dd>
<dd>
<p>
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.)
</p>
</dd>
<dd>
<p>
Sets the date on which the CDS and CDNSKEY records that match
this key are to be deleted.
