37 <p><span><strong class="command">dnssec-dsfromkey</strong></span>
38 outputs the Delegation Signer (DS) resource record (RR), as defined in
39 RFC 3658 and RFC 4509, for the given key(s).

43 <a name="id2543433"></a><h2>OPTIONS</h2>
44 <div class="variablelist"><dl>
45 <dt><span class="term">-1</span></dt>
47 Use SHA-1 as the digest algorithm (the default is to use
48 both SHA-1 and SHA-256).
50 <dt><span class="term">-2</span></dt>
52 Use SHA-256 as the digest algorithm.
54 <dt><span class="term">-a <em class="replaceable"><code>algorithm</code></em></span></dt>
56 Select the digest algorithm. The value of
57 <code class="option">algorithm</code> must be one of SHA-1 (SHA1) or
58 SHA-256 (SHA256). These values are case insensitive.
60 <dt><span class="term">-v <em class="replaceable"><code>level</code></em></span></dt>
62 Sets the debugging level.
64 <dt><span class="term">-s</span></dt>
66 Keyset mode: in place of the keyfile name, the argument is
67 the DNS domain name of a keyset file. Following options make sense
70 <dt><span class="term">-c <em class="replaceable"><code>class</code></em></span></dt>
72 Specifies the DNS class (default is IN), useful only
75 <dt><span class="term">-d <em class="replaceable"><code>directory</code></em></span></dt>
77 Look for <code class="filename">keyset</code> files in
78 <code class="option">directory</code> as the directory, ignored when
79 not in the keyset mode.

84 <a name="id2543561"></a><h2>EXAMPLE</h2>
86 To build the SHA-256 DS RR from the
87 <strong class="userinput"><code>Kexample.com.+003+26160</code></strong>
88 keyfile name, the following command would be issued:
90 <p><strong class="userinput"><code>dnssec-dsfromkey -2 Kexample.com.+003+26160</code></strong>
93 The command would print something like:
95 <p><strong class="userinput"><code>example.com. IN DS 26160 5 2 3A1EADA7A74B8D0BA86726B0C227AA85AB8BBD2B2004F41A868A54F0 C5EA0B94</code></strong>
98 <div class="refsect1" lang="en">
99 <a name="id2543591"></a><h2>FILES</h2>
101 The keyfile can be designed by the key identification
102 <code class="filename">Knnnn.+aaa+iiiii</code> or the full file name
103 <code class="filename">Knnnn.+aaa+iiiii.key</code> as generated by
104 <span class="refentrytitle">dnssec-keygen</span>(8).
107 The keyset file name is built from the <code class="option">directory</code>,
108 the string <code class="filename">keyset-</code> and the
109 <code class="option">dnsname</code>.
112 <div class="refsect1" lang="en">
113 <a name="id2543626"></a><h2>CAVEAT</h2>
115 A keyfile error can give a "file not found" even if the file exists.
