DNSSEC-VERIFY(1) BIND 9 DNSSEC-VERIFY(1)
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
This option specifies the DNS class of the zone.
-E engine
This option specifies the cryptographic hardware to use, when
applicable.
When BIND 9 is built with OpenSSL, this needs to be set to the
OpenSSL engine identifier that drives the cryptographic acceler-
ator or hardware service module (usually pkcs11).
-I input-format
This option sets the format of the input zone file. Possible
formats are text (the 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 veri-
fied independently. This option is not useful for non-dynamic
zones.
-o origin
This option indicates the zone origin. If not specified, the
name of the zone file is assumed to be the origin.
-v level
This option sets the debugging level.
-V This option prints version information.
-q This option sets quiet mode, which suppresses output. Without
this option, when dnssec-verify is run it prints to standard
output the number of keys in use, the algorithms used to verify
the zone was signed correctly, and other status information.
With this option, all non-error output is suppressed, and only
the exit code indicates success.
-x This option verifies only that the DNSKEY RRset is signed with
key-signing keys. Without this flag, it is assumed that the
DNSKEY RRset is signed by all active keys. When this flag is
set, it is not an error if the DNSKEY RRset is not signed by
zone-signing keys. This corresponds to the -x option in
dnssec-signzone.
-z This option indicates that the KSK flag on the keys should be
ignored when determining whether the zone is correctly signed.
Without this flag, it is assumed that there is a non-revoked,
self-signed DNSKEY with the KSK flag set for each algorithm, and
that RRsets other than DNSKEY RRset are signed with a different
DNSKEY without the KSK flag set.
With this flag set, BIND 9 only requires that for each algo-
rithm, there be at least one non-revoked, self-signed DNSKEY,
regardless of the KSK flag state, and that other RRsets 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
This option indicates the file containing the zone to be signed.
