53 <a name="id2604588"></a><h2>DESCRIPTION</h2>
54 <p><span><strong class="command">dnssec-keyfromlabel</strong></span>
55 gets keys with the given label from a crypto hardware and builds
56 key files for DNSSEC (Secure DNS), as defined in RFC 2535
60 <div class="refsect1" lang="en">
61 <a name="id2604602"></a><h2>OPTIONS</h2>
62 <div class="variablelist"><dl>
63 <dt><span class="term">-a <em class="replaceable"><code>algorithm</code></em></span></dt>
66 Selects the cryptographic algorithm. The value of
67 <code class="option">algorithm</code> must be one of RSAMD5,
68 RSASHA1, DSA, NSEC3RSASHA1, NSEC3DSA, RSASHA256,
69 RSASHA512 or DH (Diffie Hellman).
70 These values are case insensitive.
73 If no algorithm is specified, then RSASHA1 will be used by
74 default, unless the <code class="option">-3</code> option is specified,
75 in which case NSEC3RSASHA1 will be used instead. (If
76 <code class="option">-3</code> is used and an algorithm is specified,
77 that algorithm will be checked for compatibility with NSEC3.)
80 Note 1: that for DNSSEC, RSASHA1 is a mandatory to implement
81 algorithm, and DSA is recommended.
84 Note 2: DH automatically sets the -k flag.
87 <dt><span class="term">-l <em class="replaceable"><code>label</code></em></span></dt>
89 Specifies the label of keys in the crypto hardware
92 <dt><span class="term">-n <em class="replaceable"><code>nametype</code></em></span></dt>
94 Specifies the owner type of the key. The value of
95 <code class="option">nametype</code> must either be ZONE (for a DNSSEC
96 zone key (KEY/DNSKEY)), HOST or ENTITY (for a key associated with
98 USER (for a key associated with a user(KEY)) or OTHER (DNSKEY).
102 <dt><span class="term">-c <em class="replaceable"><code>class</code></em></span></dt>
104 Indicates that the DNS record containing the key should have
105 the specified class. If not specified, class IN is used.
107 <dt><span class="term">-f <em class="replaceable"><code>flag</code></em></span></dt>
109 Set the specified flag in the flag field of the KEY/DNSKEY record.
110 The only recognized flag is KSK (Key Signing Key) DNSKEY.
112 <dt><span class="term">-h</span></dt>
114 Prints a short summary of the options and arguments to
115 <span><strong class="command">dnssec-keygen</strong></span>.
117 <dt><span class="term">-k</span></dt>
119 Generate KEY records rather than DNSKEY records.
121 <dt><span class="term">-p <em class="replaceable"><code>protocol</code></em></span></dt>
123 Sets the protocol value for the generated key. The protocol
124 is a number between 0 and 255. The default is 3 (DNSSEC).
125 Other possible values for this argument are listed in
126 RFC 2535 and its successors.
128 <dt><span class="term">-t <em class="replaceable"><code>type</code></em></span></dt>
130 Indicates the use of the key. <code class="option">type</code> must be
131 one of AUTHCONF, NOAUTHCONF, NOAUTH, or NOCONF. The default
132 is AUTHCONF. AUTH refers to the ability to authenticate
133 data, and CONF the ability to encrypt data.
135 <dt><span class="term">-v <em class="replaceable"><code>level</code></em></span></dt>
137 Sets the debugging level.

142 <a name="id2604945"></a><h2>GENERATED KEY FILES</h2>
144 When <span><strong class="command">dnssec-keyfromlabel</strong></span> completes
146 it prints a string of the form <code class="filename">Knnnn.+aaa+iiiii</code>
147 to the standard output. This is an identification string for
148 the key files it has generated.
150 <div class="itemizedlist"><ul type="disc">
151 <li><p><code class="filename">nnnn</code> is the key name.

162 creates two files, with names based
163 on the printed string. <code class="filename">Knnnn.+aaa+iiiii.key</code>
164 contains the public key, and

172 can be inserted into a zone file (directly or with a $INCLUDE
176 The <code class="filename">.private</code> file contains algorithm
178 fields. For obvious security reasons, this file does not have
179 general read permission.
