42 <div class="variablelist"><dl class="variablelist">
43 <dt><span class="term">-c <em class="replaceable"><code>class</code></em></span></dt>
45 Specifies the DNS class of the zone.
47 <dt><span class="term">-I <em class="replaceable"><code>input-format</code></em></span></dt>
49 The format of the input zone file.
50 Possible formats are <span class="command"><strong>"text"</strong></span> (default)
51 and <span class="command"><strong>"raw"</strong></span>.
52 This option is primarily intended to be used for dynamic
53 signed zones so that the dumped zone file in a non-text
54 format containing updates can be verified independently.
55 The use of this option does not make much sense for
58 <dt><span class="term">-o <em class="replaceable"><code>origin</code></em></span></dt>
60 The zone origin. If not specified, the name of the zone file
61 is assumed to be the origin.
63 <dt><span class="term">-v <em class="replaceable"><code>level</code></em></span></dt>
65 Sets the debugging level.
67 <dt><span class="term">-V</span></dt>
69 Prints version information.
71 <dt><span class="term">-x</span></dt>
73 Only verify that the DNSKEY RRset is signed with key-signing
74 keys. Without this flag, it is assumed that the DNSKEY RRset
75 will be signed by all active keys. When this flag is set,
76 it will not be an error if the DNSKEY RRset is not signed
77 by zone-signing keys. This corresponds to the <code class="option">-x</code>
78 option in <span class="command"><strong>dnssec-signzone</strong></span>.
80 <dt><span class="term">-z</span></dt>
83 Ignore the KSK flag on the keys when determining whether
84 the zone if correctly signed. Without this flag it is
85 assumed that there will be a non-revoked, self-signed
86 DNSKEY with the KSK flag set for each algorithm and
87 that RRsets other than DNSKEY RRset will be signed with
88 a different DNSKEY without the KSK flag set.
91 With this flag set, we only require that for each algorithm,
92 there will be at least one non-revoked, self-signed DNSKEY,
93 regardless of the KSK flag state, and that other RRsets
94 will be signed by a non-revoked key for the same algorithm
95 that includes the self-signed key; the same key may be used
96 for both purposes. This corresponds to the <code class="option">-z</code>
97 option in <span class="command"><strong>dnssec-signzone</strong></span>.
100 <dt><span class="term">zonefile</span></dt>
102 The file containing the zone to be signed.
