<p><span><strong class="command">dnssec-dsfromkey</strong></span>
|

|

<div class="variablelist"><dl>
|

<dt><span class="term">-1</span></dt>
|
||
<dd><p>
|
||
Use SHA-1 as the digest algorithm (the default is to use
|
||
both SHA-1 and SHA-256).
|
||
</p></dd>
|
||
<dt><span class="term">-2</span></dt>
|

<dd><p>
|

Use SHA-256 as the digest algorithm.
|

</p></dd>
|
||
<dt><span class="term">-a <em class="replaceable"><code>algorithm</code></em></span></dt>
|
||
<dd><p>
|
||
Select the digest algorithm. The value of
|
||
<code class="option">algorithm</code> must be one of SHA-1 (SHA1),
|
||
SHA-256 (SHA256) or GOST. These values are case insensitive.
|
||
</p></dd>
|
||
<dt><span class="term">-K <em class="replaceable"><code>directory</code></em></span></dt>
|
||
<dd><p>
|
||
Look for key files (or, in keyset mode,
|
||
<code class="filename">keyset-</code> files) in
|
||
<code class="option">directory</code>.
|
||
</p></dd>
|
||
<dt><span class="term">-f <em class="replaceable"><code>file</code></em></span></dt>
|
||
<dd><p>
|
||
Zone file mode: in place of the 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 zone name is the same as
|
||
<code class="option">file</code>, then it may be omitted.
|
||
</p></dd>
|
||
<dt><span class="term">-A</span></dt>
|
||
<dd><p>
|
||
Include ZSK's when generating DS records. Without this option,
|
||
only keys which have the KSK flag set will be converted to DS
|
||
records and printed. Useful only in zone file mode.
|
||
</p></dd>
|
||
<dt><span class="term">-l <em class="replaceable"><code>domain</code></em></span></dt>
|
||
<dd><p>
|
||
Generate a DLV set instead of a DS set. The specified
|
||
<code class="option">domain</code> is appended to the name for each
|
||
record in the set.
|
||
The DNSSEC Lookaside Validation (DLV) RR is described
|
||
in RFC 4431.
|
||
</p></dd>
|
||
<dt><span class="term">-s</span></dt>
|

Keyset mode: in place of the keyfile name, the argument is
|
||
the DNS domain name of a keyset file.
|
||
</p></dd>
|
||
<dt><span class="term">-c <em class="replaceable"><code>class</code></em></span></dt>

<dd><p>

Specifies the DNS class (default is IN). Useful only

in keyset or zone file mode.

</p></dd>
|

<dt><span class="term">-v <em class="replaceable"><code>level</code></em></span></dt>

<a name="id2612526"></a><h2>EXAMPLE</h2>
|
||
<p>
|
||
To build the SHA-256 DS RR from the
|
||
<strong class="userinput"><code>Kexample.com.+003+26160</code></strong>
|
||
keyfile name, the following command would be issued:
|
||
</p>
|
||
<p><strong class="userinput"><code>dnssec-dsfromkey -2 Kexample.com.+003+26160</code></strong>
|
||
</p>
|
||
<p>
|
||
The command would print something like:
|
||
</p>
|
||
<p><strong class="userinput"><code>example.com. IN DS 26160 5 2 3A1EADA7A74B8D0BA86726B0C227AA85AB8BBD2B2004F41A868A54F0 C5EA0B94</code></strong>
|
||
</p>
|
||
</div>
|
||
<div class="refsect1" lang="en">
|
||
<a name="id2612563"></a><h2>FILES</h2>
|
||
<p>
|
||
The keyfile can be designed by the key identification
|
||
<code class="filename">Knnnn.+aaa+iiiii</code> or the full file name
|
||
<code class="filename">Knnnn.+aaa+iiiii.key</code> as generated by
|
||
<span class="refentrytitle">dnssec-keygen</span>(8).
|
||
</p>
|
||
<p>
|
||
The keyset file name is built from the <code class="option">directory</code>,
|
||
the string <code class="filename">keyset-</code> and the
|
||
<code class="option">dnsname</code>.
|
||
</p>
|

|
||
<div class="refsect1" lang="en">
|

<a name="id2612604"></a><h2>CAVEAT</h2>
|
||
<p>
|
||
A keyfile error can give a "file not found" even if the file exists.

||
