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.
