retrieve the DNSSEC DNSKEYs for a zone


ldns-keyfetcher [ Options ] DOMAIN


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.


Only use IPv4
Only use IPv6
Show a help text and exit
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.
Don't print the keys to stdout, but store them in files.

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