2.4. Wire Format of the DS record
|
||
|
|
|
||
|
|
The DS (type=43) record contains these fields: key tag, algorithm,
|
||
|
|
digest type, and the digest of a public key KEY record that is
|
||
|
|
allowed and/or used to sign the child's apex KEY RRset. Other keys
|
||
|
|
MAY sign the child's apex KEY RRset.
