[Unbound-users] DNSSEC and traffic encryption questions

Drill does not have a pre-configured or built-in trust anchor (e.g. the
root key); So the only thing it can say right now is that the crypto
*looks* ok, relative to the other records it finds, hence an [S] instead
of a [T].

If you pass it a key with -k it should print about the same, but with
[T] values.

$ drill -k ~/root.key -TD com. SOA

One insecure way to easily get the root key is ldns-keyfetcher -s (it
simply does a query and stores the result)
