DNSSEC-VERIFY(8) BIND 9 DNSSEC-VERIFY(8)
NAME
dnssec-verify - DNSSEC zone verification tool
SYNOPSIS
dnssec-verify [-c class] [-E engine] [-I input-format] [-o origin] [-q]
[-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 mod-
ule. When BIND is built with native PKCS#11 cryptography (--en-
able-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 indepen-
dently. 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.
-q Quiet mode: Suppresses output. Without this option, when
dnssec-verify is run it will print to standard output the number
of keys in use, the algorithms used to verify the zone was
signed correctly and other status information. With it, all
non-error output is suppressed, and only the exit code will in-
dicate success.
-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, re-
gardless 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.
