ldns-keyfetcher(1)	     General Commands Manual	      ldns-keyfetcher(1)

NAME
     ldns-keyfetcher - retrieve the DNSSEC DNSKEYs for a zone

SYNOPSIS
     ldns-keyfetcher [ OPTIONS ] DOMAIN

DESCRIPTION
     ldns-keyfetcher is used to retrieve the DNSKEYs of a zone.

     First it finds all authoritative nameservers of the zone by tracing it from
     the  root	down. All authoritative nameservers are then queried (using TCP)
     for the DNSKEY RRset of the zone apex. If the results are all the same, the
     key resource record set is printed.

OPTIONS
     -4 Only use IPv4

     -6 Only use IPv6

     -h Show a help text and exit

     -i Insecurer mode; there will only be one query for the DNSKEYS. There will
     not be crosschecking of all authoritative nameservers.

     -v verbosity

     Set the verbosity level. The following levels are available:

      0: default, only print the DNSKEY RRset found, or an error on failure.
      1: Show the nameservers that are queried
      2: Show more info on what is checked
      3: Show the intermediate results (authority and dnskey rrsets)
      4: Print the answer packets that are returned

     -r file

     Use file as the root hints file, should contain A records	in  presentation
     format.  The  default  is	/etc/named.root.  You  can  get  this  file from
     http://www.internic.net/zones/named.root.

     -s Don't print the keys to stdout, but store them in files.

     The filenames will be of the format K<file>.+<alg>.+<keytag>.key
