0ba2cbe97e0678a691742f98d2532caed0a2c4aaxc verifies that a zone is fully signed for each algorithm found
0ba2cbe97e0678a691742f98d2532caed0a2c4aaxc in the DNSKEY RRset for the zone, and that the NSEC / NSEC3
0ba2cbe97e0678a691742f98d2532caed0a2c4aaxc chains are complete.
0ba2cbe97e0678a691742f98d2532caed0a2c4aaxc<dt><span class="term">-c <em class="replaceable"><code>class</code></em></span></dt>
0ba2cbe97e0678a691742f98d2532caed0a2c4aaxc Specifies the DNS class of the zone.
0ba2cbe97e0678a691742f98d2532caed0a2c4aaxc<dt><span class="term">-E <em class="replaceable"><code>engine</code></em></span></dt>
0ba2cbe97e0678a691742f98d2532caed0a2c4aaxc Specifies the cryptographic hardware to use, when applicable.
0ba2cbe97e0678a691742f98d2532caed0a2c4aaxc When BIND is built with OpenSSL PKCS#11 support, this defaults
0ba2cbe97e0678a691742f98d2532caed0a2c4aaxc to the string "pkcs11", which identifies an OpenSSL engine
0ba2cbe97e0678a691742f98d2532caed0a2c4aaxc that can drive a cryptographic accelerator or hardware service
0ba2cbe97e0678a691742f98d2532caed0a2c4aaxc module. When BIND is built with native PKCS#11 cryptography
0ba2cbe97e0678a691742f98d2532caed0a2c4aaxc (--enable-native-pkcs11), it defaults to the path of the PKCS#11
0ba2cbe97e0678a691742f98d2532caed0a2c4aaxc provider library specified via "--with-pkcs11".
0ba2cbe97e0678a691742f98d2532caed0a2c4aaxc<dt><span class="term">-I <em class="replaceable"><code>input-format</code></em></span></dt>
0ba2cbe97e0678a691742f98d2532caed0a2c4aaxc The format of the input zone file.
0ba2cbe97e0678a691742f98d2532caed0a2c4aaxc Possible formats are <span><strong class="command">"text"</strong></span> (default)
0ba2cbe97e0678a691742f98d2532caed0a2c4aaxc This option is primarily intended to be used for dynamic
0ba2cbe97e0678a691742f98d2532caed0a2c4aaxc signed zones so that the dumped zone file in a non-text
0ba2cbe97e0678a691742f98d2532caed0a2c4aaxc format containing updates can be verified independently.
0ba2cbe97e0678a691742f98d2532caed0a2c4aaxc The use of this option does not make much sense for
0ba2cbe97e0678a691742f98d2532caed0a2c4aaxc non-dynamic zones.
0ba2cbe97e0678a691742f98d2532caed0a2c4aaxc<dt><span class="term">-o <em class="replaceable"><code>origin</code></em></span></dt>
0ba2cbe97e0678a691742f98d2532caed0a2c4aaxc The zone origin. If not specified, the name of the zone file
0ba2cbe97e0678a691742f98d2532caed0a2c4aaxc is assumed to be the origin.
0ba2cbe97e0678a691742f98d2532caed0a2c4aaxc<dt><span class="term">-v <em class="replaceable"><code>level</code></em></span></dt>
0ba2cbe97e0678a691742f98d2532caed0a2c4aaxc Sets the debugging level.

239e91abc172c1397b1e94869c5d0e8ab67bfc22hx Only verify that the DNSKEY RRset is signed with key-signing
0ba2cbe97e0678a691742f98d2532caed0a2c4aaxc keys. Without this flag, it is assumed that the DNSKEY RRset
0ba2cbe97e0678a691742f98d2532caed0a2c4aaxc will be signed by all active keys. When this flag is set,
0ba2cbe97e0678a691742f98d2532caed0a2c4aaxc it will not be an error if the DNSKEY RRset is not signed
0ba2cbe97e0678a691742f98d2532caed0a2c4aaxc by zone-signing keys. This corresponds to the <code class="option">-x</code>
0ba2cbe97e0678a691742f98d2532caed0a2c4aaxc option in <span><strong class="command">dnssec-signzone</strong></span>.
0ba2cbe97e0678a691742f98d2532caed0a2c4aaxc Ignore the KSK flag on the keys when determining whether
0ba2cbe97e0678a691742f98d2532caed0a2c4aaxc the zone if correctly signed. Without this flag it is
0ba2cbe97e0678a691742f98d2532caed0a2c4aaxc assumed that there will be a non-revoked, self-signed
0ba2cbe97e0678a691742f98d2532caed0a2c4aaxc DNSKEY with the KSK flag set for each algorithm and
0ba2cbe97e0678a691742f98d2532caed0a2c4aaxc that RRsets other than DNSKEY RRset will be signed with
0ba2cbe97e0678a691742f98d2532caed0a2c4aaxc a different DNSKEY without the KSK flag set.
0ba2cbe97e0678a691742f98d2532caed0a2c4aaxc With this flag set, we only require that for each algorithm,
0ba2cbe97e0678a691742f98d2532caed0a2c4aaxc there will be at least one non-revoked, self-signed DNSKEY,
0ba2cbe97e0678a691742f98d2532caed0a2c4aaxc regardless of the KSK flag state, and that other RRsets
0ba2cbe97e0678a691742f98d2532caed0a2c4aaxc will be signed by a non-revoked key for the same algorithm
0ba2cbe97e0678a691742f98d2532caed0a2c4aaxc that includes the self-signed key; the same key may be used
0ba2cbe97e0678a691742f98d2532caed0a2c4aaxc for both purposes. This corresponds to the <code class="option">-z</code>
