The DNS Security Extensions (DNSSEC) were developed to provide origin
authentication and integrity protection for DNS data by using digital
signatures.  These digital signatures can be generated using
different algorithms.  This document specifies a way for validating
end-system resolvers to signal to a server which digital signature
and hash algorithms they support.  The extensions allow the signaling
of new algorithm uptake in client code to allow zone administrators
to know when it is possible to complete an algorithm rollover in a
DNSSEC-signed zone.

This document is a product of the DNS Extensions Working Group of the IETF.

This is now a Proposed Standard.
