<para><command>dnssec-verify</command>

verifies that a zone is fully signed for each algorithm found

in the DNSKEY RRset for the zone, and that the NSEC / NSEC3

chains are complete.

<variablelist>

<varlistentry>

<term>-c <replaceable class="parameter">class</replaceable></term>

<listitem>

<para>

Specifies the DNS class of the zone.

<listitem>

<para>

Specifies the cryptographic hardware to use, when applicable.

</para>

<para>

When BIND is built with OpenSSL PKCS#11 support, this defaults

to the string "pkcs11", which identifies an OpenSSL engine

that can drive a cryptographic accelerator or hardware service

module. When BIND is built with native PKCS#11 cryptography

(--enable-native-pkcs11), it defaults to the path of the PKCS#11

provider library specified via "--with-pkcs11".

</para>

</listitem>

</varlistentry>

<varlistentry>

<term>-I <replaceable class="parameter">input-format</replaceable></term>

<listitem>

<para>

The format of the input zone file.

Possible formats are <command>"text"</command> (default)

and <command>"raw"</command>.

This option is primarily intended to be used for dynamic

signed zones so that the dumped zone file in a non-text

format containing updates can be verified independently.

The use of this option does not make much sense for

non-dynamic zones.

</para>

</listitem>

</varlistentry>

<varlistentry>

<term>-o <replaceable class="parameter">origin</replaceable></term>

<listitem>

<para>

The zone origin. If not specified, the name of the zone file

is assumed to be the origin.

<listitem>

<para>

Prints version information.

</para>

</listitem>

</varlistentry>

<varlistentry>

<term>-x</term>

<listitem>

<para>

Only verify that the DNSKEY RRset is signed with key-signing

keys. Without this flag, it is assumed that the DNSKEY RRset

will be signed by all active keys. When this flag is set,

it will not be an error if the DNSKEY RRset is not signed

by zone-signing keys. This corresponds to the <option>-x</option>

option in <command>dnssec-signzone</command>.

</para>

</listitem>

</varlistentry>

<varlistentry>

<term>-z</term>

<listitem>

<para>

Ignore the KSK flag on the keys when determining whether

the zone if correctly signed. Without this flag it is

assumed that there will be a non-revoked, self-signed

DNSKEY with the KSK flag set for each algorithm and

that RRsets other than DNSKEY RRset will be signed with

a different DNSKEY without the KSK flag set.

</para>

<para>

With this flag set, we only require that for each algorithm,

there will be at least one non-revoked, self-signed DNSKEY,

regardless of the KSK flag state, and that other RRsets

will be signed by a non-revoked key for the same algorithm

that includes the self-signed key; the same key may be used

for both purposes. This corresponds to the <option>-z</option>

option in <command>dnssec-signzone</command>.
