 ## DNSSEC dependencies

+When the root trust anchor is not installed in the default location and a DNSSEC query is done, getdns will try to use the trust anchors published here: http://data.iana.org/root-anchors/root-anchors.xml .
+It will validate these anchors with the ICANN Certificate Authority certificate following the procedure described in [RFC7958].
+The `root-anchors.xml` and `root-anchors.p7s` S/MIME signature will be cached in the `$HOME/.getdns` directory.

+When using trust-anchors from the `root-anchors.xml` file, getdns will track the keys in the root DNSKEY rrset and store a copy in $HOME/.getdns/root.key.
