|
||
<p><span><strong class="command">dnssec-keyfromlabel</strong></span>
|
||
gets keys with the given label from a crypto hardware and builds
|
||
key files for DNSSEC (Secure DNS), as defined in RFC 2535
|
||
and RFC 4034.
|
||
</p>

<div class="variablelist"><dl>
|
||
<dt><span class="term">-a <em class="replaceable"><code>algorithm</code></em></span></dt>
|
||
<dd>
|
||
<p>
|
||
Selects the cryptographic algorithm. The value of
|
||
<code class="option">algorithm</code> must be one of RSAMD5 (RSA)
|
||
or RSASHA1, DSA, NSEC3RSASHA1, NSEC3DSA or DH (Diffie Hellman).
|
||
These values are case insensitive.
|
||
</p>
|
||
<p>
|
||
Note 1: that for DNSSEC, RSASHA1 is a mandatory to implement
|
||
algorithm, and DSA is recommended.
|
||
</p>
|
||
<p>
|
||
Note 2: DH automatically sets the -k flag.
|
||
</p>
|
||
</dd>
|
||
<dt><span class="term">-l <em class="replaceable"><code>label</code></em></span></dt>
|

Specifies the label of keys in the crypto hardware
|

(PKCS#11 device).
|
||
</p></dd>
|
||
<dt><span class="term">-n <em class="replaceable"><code>nametype</code></em></span></dt>
|
||
<dd><p>
|
||
Specifies the owner type of the key. The value of
|
||
<code class="option">nametype</code> must either be ZONE (for a DNSSEC
|
||
zone key (KEY/DNSKEY)), HOST or ENTITY (for a key associated with
|
||
a host (KEY)),
|
||
USER (for a key associated with a user(KEY)) or OTHER (DNSKEY).
|
||
These values are
|
||
case insensitive.
|
||
</p></dd>
|
||
<dt><span class="term">-c <em class="replaceable"><code>class</code></em></span></dt>
|

<dd><p>
|

Indicates that the DNS record containing the key should have
|

the specified class. If not specified, class IN is used.
|

</p></dd>
|
||
<dt><span class="term">-f <em class="replaceable"><code>flag</code></em></span></dt>
|
||
<dd><p>
|
||
Set the specified flag in the flag field of the KEY/DNSKEY record.
|
||
The only recognized flag is KSK (Key Signing Key) DNSKEY.
|
||
</p></dd>
|

<dt><span class="term">-h</span></dt>

|

Prints a short summary of the options and arguments to

</p></dd>

<dt><span class="term">-k</span></dt>

Generate KEY records rather than DNSKEY records.
|

</p></dd>
|
||
<dt><span class="term">-p <em class="replaceable"><code>protocol</code></em></span></dt>
|
||
<dd><p>
|
||
Sets the protocol value for the generated key. The protocol
|
||
is a number between 0 and 255. The default is 3 (DNSSEC).
|
||
Other possible values for this argument are listed in
|
||
RFC 2535 and its successors.

</p></dd>
|
||
<dt><span class="term">-t <em class="replaceable"><code>type</code></em></span></dt>
|
||
<dd><p>
|
||
Indicates the use of the key. <code class="option">type</code> must be
|
||
one of AUTHCONF, NOAUTHCONF, NOAUTH, or NOCONF. The default
|
||
is AUTHCONF. AUTH refers to the ability to authenticate
|
||
data, and CONF the ability to encrypt data.
|
||
</p></dd>
|
||
<dt><span class="term">-v <em class="replaceable"><code>level</code></em></span></dt>

|
||
<p>
|
||
When <span><strong class="command">dnssec-keyfromlabel</strong></span> completes
|
||
successfully,
|
||
it prints a string of the form <code class="filename">Knnnn.+aaa+iiiii</code>
|
||
to the standard output. This is an identification string for
|
||
the key files it has generated.
|
||
</p>
|
||
<div class="itemizedlist"><ul type="disc">
|
||
<li><p><code class="filename">nnnn</code> is the key name.
|
||
</p></li>
|
||
<li><p><code class="filename">aaa</code> is the numeric representation
|
||
of the
|
||
algorithm.
|
||
</p></li>
|
||
<li><p><code class="filename">iiiii</code> is the key identifier (or
|
||
footprint).
|
||
</p></li>
|
||
</ul></div>
|
||
<p><span><strong class="command">dnssec-keyfromlabel</strong></span>
|
||
creates two files, with names based
|
||
on the printed string. <code class="filename">Knnnn.+aaa+iiiii.key</code>
|
||
contains the public key, and
|
||
<code class="filename">Knnnn.+aaa+iiiii.private</code> contains the
|
||
private
|
||
key.
|
||
</p>
|
||
<p>
|
||
The <code class="filename">.key</code> file contains a DNS KEY record
|
||
that
|
||
can be inserted into a zone file (directly or with a $INCLUDE
|
||
statement).
|
||
</p>
|
||
<p>
|
||
The <code class="filename">.private</code> file contains algorithm
|
||
specific
|
||
fields. For obvious security reasons, this file does not have
|
||
general read permission.
