Hi Sven,

Unbound does not support this sort of debug activities.  It is meant as
validating resolver.  Debug tools are much better suited for the task.
If you want to make such tools as you describe below, the library ldns
(nlnetlabs.nl/ldns) could be the thing you are looking for.

The example tool ldns-keyfetcher comes close - it queries nameservers
for a DNSKEY and if same prints it to stdout.  It is not parallel.

Best regards,
   Wouter
