DNSSEC-VERIFY(8)						       BIND9							  DNSSEC-VERIFY(8)

NAME

       dnssec-verify - DNSSEC zone verification tool

SYNOPSIS

       dnssec-verify [-c class] [-E engine] [-I input-format] [-o origin] [-v level] [-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.

       -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.

       -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.
