1. Introduction
IPSECKEY [RFC4025) [RFC4025] is a resource record (RR) for the Domain Name
System (DNS) that is used to store public keys for use in IP security
(IPsec) systems. The IPSECKEY RR relies on the IPSECKEY Algorithm "Algorithm
Type Field Field" registry [IANA-IPSECKEY] to enumerate the permissible
formats for the public keys.
This document adds support for Edwards-Curve Digital Security
Algorithm (EdDSA) public keys in the format defined in [RFC8080] to
the IPSECKEY RR.
2. IPSECKEY support Support for EdDSA
When using the EdDSA public key in the IPSECKEY RR, then the value
TBD1 4 is
used as an algorithm and the public key is formatted as specified in Section 3 of the
"Edwards-Curve Digital Security Algorithm (EdDSA) for DNSSEC" ([RFC8080]) document.
(Section 3 of [RFC8080]).

3. IANA Considerations
3.1. Update to the IANA IPSECKEY Registry Update
3.1.1. Reformat the Algorithm Type Field Subregistry
This document requests Registry
Per this document, IANA to add a new field has added the "Format description" Description" field to
the "Algorithm Type Field" subregistry registry of the "IPSECKEY Resource Record
Parameters" [IANA-IPSECKEY]. Also, this document requests In addition, IANA to update has updated the
"Description" field in existing entries of that registry to
explicitly state that is they are for "Public" keys:
+=======+==========================+====================+===========+
| Value | Description | Format description Description | Reference |
+=======+==========================+====================+===========+

IANA is requested to update the added a reference of that registry by adding
the RFC number to be assigned to this document. document to the "Algorithm Type Field"
registry.
3.1.2. Add to the Algorithm Type Field Subregistry Registry
Further, this document requests IANA to make has made the following addition to the "IPSECKEY Resource Record Parameters" [IANA-IPSECKEY]
registry:
IPSECKEY:
This document defines the new IPSECKEY value TBD1 (suggested: 4)
(Section 2) in the "Algorithm Type
Field" subregistry of registry within the "IPSECKEY Resource Record Parameters" registry.

Appendix A. IPSECKEY EdDSA example Example
The following is an example of an IPSECKEY RR with no gateway, and an
EdDSA public
key base64 encode with no gateway: key. It uses the IPSECKEY presentation format which is
base64.

10 0 4 . 3WTXgUvpn1RlCXnm80gGY2LZ/ErUUEZtZ33IDi8yfhM= )
The associated EdDSA private key (in hex): hex) is as follows:
