== Format of TLS Extension ==
asdfThe "extension_data" field of the client hello extension currently consists of no data (i.e. it is empty and of zero length) and serves only as an indication that a DNSSEC chain has been requested. In the future this may be changed to allow for an optimization whereby the server can send less data. The "extension_data" field of the server hello extension contains "DNSSECChain" where: <nowiki> struct { RR resource_record_chain<1..> } DNSSECChain;</nowiki> Each resource record ("RR") in the chain is in wire format as described by the appropriate RFC (see for example [http://www.ietf.org/rfc/rfc1035.txt rfc 1035]). The contents of this chain are described [[Security/DNSSEC-TLS-details#DNSSEC Chains | above]].
