+<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>
+<dd><p>
+ 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">-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>
+ 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.
