class Dnsruby::RR::CDS
RFC4034, section 4 The DS
Resource Record refers to a DNSKEY
RR
and is used in the DNS
DNSKEY
authentication process. A DS
RR
refers to a DNSKEY
RR
by storing the key tag, algorithm number, and a digest of the DNSKEY
RR
. Note that while the digest should be sufficient to identify the public key, storing the key tag and key algorithm helps make the identification process more efficient. By authenticating the DS
record, a resolver can authenticate the DNSKEY
RR
to which the DS
record points. The key authentication process is described in [RFC4035].
