bb8874d71cdd8e5288297b9727703437c6dfcfedmatthew_swift<p><span class="command"><strong>dnssec-verify</strong></span>
28672111658d1ed073638d2ed326a32aef523dc2ludovicp verifies that a zone is fully signed for each algorithm found
28672111658d1ed073638d2ed326a32aef523dc2ludovicp in the DNSKEY RRset for the zone, and that the NSEC / NSEC3
28672111658d1ed073638d2ed326a32aef523dc2ludovicp chains are complete.

bb8874d71cdd8e5288297b9727703437c6dfcfedmatthew_swift Specifies the DNS class of the zone.
bb8874d71cdd8e5288297b9727703437c6dfcfedmatthew_swift<dt><span class="term">-E <em class="replaceable"><code>engine</code></em></span></dt>
cd845149d3f0adb85c23d522477ffb6d7c16cc7ectissot Specifies the cryptographic hardware to use, when applicable.
bb8874d71cdd8e5288297b9727703437c6dfcfedmatthew_swift When BIND is built with OpenSSL PKCS#11 support, this defaults
cd845149d3f0adb85c23d522477ffb6d7c16cc7ectissot to the string "pkcs11", which identifies an OpenSSL engine
bb8874d71cdd8e5288297b9727703437c6dfcfedmatthew_swift that can drive a cryptographic accelerator or hardware service
bb8874d71cdd8e5288297b9727703437c6dfcfedmatthew_swift module. When BIND is built with native PKCS#11 cryptography
bb8874d71cdd8e5288297b9727703437c6dfcfedmatthew_swift (--enable-native-pkcs11), it defaults to the path of the PKCS#11
bb8874d71cdd8e5288297b9727703437c6dfcfedmatthew_swift provider library specified via "--with-pkcs11".
bb8874d71cdd8e5288297b9727703437c6dfcfedmatthew_swift<dt><span class="term">-I <em class="replaceable"><code>input-format</code></em></span></dt>
bb8874d71cdd8e5288297b9727703437c6dfcfedmatthew_swift The format of the input zone file.
bb8874d71cdd8e5288297b9727703437c6dfcfedmatthew_swift Possible formats are <span class="command"><strong>"text"</strong></span> (default)
bb8874d71cdd8e5288297b9727703437c6dfcfedmatthew_swift and <span class="command"><strong>"raw"</strong></span>.
bb8874d71cdd8e5288297b9727703437c6dfcfedmatthew_swift This option is primarily intended to be used for dynamic
bb8874d71cdd8e5288297b9727703437c6dfcfedmatthew_swift signed zones so that the dumped zone file in a non-text
bb8874d71cdd8e5288297b9727703437c6dfcfedmatthew_swift format containing updates can be verified independently.
bb8874d71cdd8e5288297b9727703437c6dfcfedmatthew_swift The use of this option does not make much sense for
bb8874d71cdd8e5288297b9727703437c6dfcfedmatthew_swift non-dynamic zones.
bb8874d71cdd8e5288297b9727703437c6dfcfedmatthew_swift<dt><span class="term">-o <em class="replaceable"><code>origin</code></em></span></dt>
bb8874d71cdd8e5288297b9727703437c6dfcfedmatthew_swift The zone origin. If not specified, the name of the zone file
bb8874d71cdd8e5288297b9727703437c6dfcfedmatthew_swift is assumed to be the origin.
28672111658d1ed073638d2ed326a32aef523dc2ludovicp<dt><span class="term">-v <em class="replaceable"><code>level</code></em></span></dt>
28672111658d1ed073638d2ed326a32aef523dc2ludovicp Sets the debugging level.
bb8874d71cdd8e5288297b9727703437c6dfcfedmatthew_swift Prints version information.
bb8874d71cdd8e5288297b9727703437c6dfcfedmatthew_swift Only verify that the DNSKEY RRset is signed with key-signing
bb8874d71cdd8e5288297b9727703437c6dfcfedmatthew_swift keys. Without this flag, it is assumed that the DNSKEY RRset
bb8874d71cdd8e5288297b9727703437c6dfcfedmatthew_swift will be signed by all active keys. When this flag is set,
bb8874d71cdd8e5288297b9727703437c6dfcfedmatthew_swift it will not be an error if the DNSKEY RRset is not signed
cd845149d3f0adb85c23d522477ffb6d7c16cc7ectissot by zone-signing keys. This corresponds to the <code class="option">-x</code>
bb8874d71cdd8e5288297b9727703437c6dfcfedmatthew_swift option in <span class="command"><strong>dnssec-signzone</strong></span>.
bb8874d71cdd8e5288297b9727703437c6dfcfedmatthew_swift Ignore the KSK flag on the keys when determining whether
bb8874d71cdd8e5288297b9727703437c6dfcfedmatthew_swift the zone if correctly signed. Without this flag it is
bb8874d71cdd8e5288297b9727703437c6dfcfedmatthew_swift assumed that there will be a non-revoked, self-signed
bb8874d71cdd8e5288297b9727703437c6dfcfedmatthew_swift DNSKEY with the KSK flag set for each algorithm and
bb8874d71cdd8e5288297b9727703437c6dfcfedmatthew_swift that RRsets other than DNSKEY RRset will be signed with
bb8874d71cdd8e5288297b9727703437c6dfcfedmatthew_swift a different DNSKEY without the KSK flag set.
bb8874d71cdd8e5288297b9727703437c6dfcfedmatthew_swift With this flag set, we only require that for each algorithm,
bb8874d71cdd8e5288297b9727703437c6dfcfedmatthew_swift there will be at least one non-revoked, self-signed DNSKEY,
bb8874d71cdd8e5288297b9727703437c6dfcfedmatthew_swift regardless of the KSK flag state, and that other RRsets
bb8874d71cdd8e5288297b9727703437c6dfcfedmatthew_swift will be signed by a non-revoked key for the same algorithm
bb8874d71cdd8e5288297b9727703437c6dfcfedmatthew_swift that includes the self-signed key; the same key may be used
bb8874d71cdd8e5288297b9727703437c6dfcfedmatthew_swift for both purposes. This corresponds to the <code class="option">-z</code>
bb8874d71cdd8e5288297b9727703437c6dfcfedmatthew_swift option in <span class="command"><strong>dnssec-signzone</strong></span>.
