NAME

       dnssec-verify - DNSSEC zone verification tool

SYNOPSIS


       dnssec-verify [-c class] [-E engine] [-I input-format] [-o origin] [-v level] [-V] [-x] [-z] {zonefile}

DESCRIPTION

       dnssec-verify 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.

OPTIONS

-c class
Specifies the DNS class of the zone.

-E engine
Specifies the cryptographic hardware to use, when applicable.

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".

-I input-format
The format of the input zone file. Possible formats are "text" (default) and "raw". 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.

-o origin
The zone origin. If not specified, the name of the zone file is assumed to be the origin.

-v level
Sets the debugging level.

-V
Prints version information.

-x
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 -x option in
dnssec-signzone.

-z
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.

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 -z option in dnssec-signzone.

zonefile
The file containing the zone to be signed.
