NAME
       ldns-verify-zone - read a DNSSEC signed zone and verify it.

SYNOPSIS
       ldns-verify-zone ZONEFILE

DESCRIPTION
       ldns-verify-zone reads a DNS zone file and verifies it.

       RRSIG resource records are checked against the DNSKEY set at the zone
       apex.

       Each name is checked for an NSEC(3), if appropriate.

OPTIONS
       -h     Show usage and exit

       -a     Apex only, check only the zone apex

       -e period
              Signatures may not expire within this period.  Default no period
              is used.

       -i period
              Signatures must have been valid at least this long.  Default
              signatures should just be valid now.

       -k file
              A file that contains a trusted DNSKEY or DS rr.  This option may
              be given more than once.

              Alternatively, if -k is not specified, and a default trust
              anchor (/usr/local/etc/unbound/root.key) exists and contains a
              valid DNSKEY or DS record, it will be used as the trust anchor.

       -p [0-100]
              Only check this percentage of the zone.  Which names to check is
              determined randomly.  Defaults to 100.

       -S     Chase signature(s) to a known key.  The network may be accessed
              to validate the zone's DNSKEYs. (implies -k)

       -t YYYYMMDDhhmmss | [+|-]offset
              Set the validation time either by an absolute time value or as
              an offset in seconds from the current time.

       -v     Show the version and exit

       -V number
              Set the verbosity level (default 3):

               0: Be silent
               1: Print result, and any errors
               2: Same as 1 for now
               3: Print result, any errors, and the names that are
                  being checked
               4: Same as 3 for now
               5: Print the zone after it has been read, the result,
                  any errors, and the names that are being checked

       periods are given in ISO 8601 duration format:
              P[n]Y[n]M[n]DT[n]H[n]M[n]S

       If no file is given standard input is read.

FILES
       /usr/local/etc/unbound/root.key
              The file from which trusted keys are loaded for signature
              chasing, when no -k option is given.
