59 <title>DESCRIPTION</title>
60 <para><command>dnssec-verify</command>
61 verifies that a zone is fully signed for each algorithm found
62 in the DNSKEY RRset for the zone, and that the NSEC / NSEC3
68 <title>OPTIONS</title>
72 <term>-c <replaceable class="parameter">class</replaceable></term>
75 Specifies the DNS class of the zone.
81 <term>-I <replaceable class="parameter">input-format</replaceable></term>
84 The format of the input zone file.
85 Possible formats are <command>"text"</command> (default)
86 and <command>"raw"</command>.
87 This option is primarily intended to be used for dynamic
88 signed zones so that the dumped zone file in a non-text
89 format containing updates can be verified independently.
90 The use of this option does not make much sense for
97 <term>-o <replaceable class="parameter">origin</replaceable></term>
100 The zone origin. If not specified, the name of the zone file
101 is assumed to be the origin.
107 <term>-v <replaceable class="parameter">level</replaceable></term>
110 Sets the debugging level.
119 Only verify that the DNSKEY RRset is signed with key-signing
120 keys. Without this flag, it is assumed that the DNSKEY RRset
121 will be signed by all active keys. When this flag is set,
122 it will not be an error if the DNSKEY RRset is not signed
123 by zone-signing keys. This corresponds to the <option>-x</option>
124 option in <command>dnssec-signzone</command>.
133 Ignore the KSK flag on the keys when determining whether
134 the zone if correctly signed. Without this flag it is
135 assumed that there will be a non-revoked, self-signed
136 DNSKEY with the KSK flag set for each algorithm and
137 that RRsets other than DNSKEY RRset will be signed with
138 a different DNSKEY without the KSK flag set.
141 With this flag set, we only require that for each algorithm,
142 there will be at least one non-revoked, self-signed DNSKEY,
143 regardless of the KSK flag state, and that other RRsets
144 will be signed by a non-revoked key for the same algorithm
145 that includes the self-signed key; the same key may be used
146 for both purposes. This corresponds to the <option>-z</option>
147 option in <command>dnssec-signzone</command>.
153 <term>zonefile</term>
156 The file containing the zone to be signed.
