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] [-J filename] [-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  com-
     plete.

OPTIONS
     -c class
	    This option specifies the DNS class of the zone.

     -E engine
	    This  option  specifies  the cryptographic hardware to use, when ap-
	    plicable.

	    When BIND 9 is built with OpenSSL, this  needs  to	be  set  to  the
	    OpenSSL  engine identifier that drives the cryptographic accelerator
	    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 verified independently.
	    This option is not useful for non-dynamic zones.

     -J filename
	    This option tells dnssec-verify to read the journal from  the  given
	    file when loading the zone file.

     -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   <#
	    cmdoption-dnssec-signzone-x>.

     -z     This  option  indicates  that the KSK flag on the keys should be ig-
	    nored 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 algorithm,
	    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 <#cmdoption-dnssec-signzone-z>.

     zonefile
	    This option indicates the file containing the zone to be signed.
