1. Introduction
IPSECKEY [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
Type 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 for EdDSA
When using the EdDSA public key in the IPSECKEY RR, then the value
TBD1 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.
Value Description Format description Reference
TBD1 An EdDSA Public Key [RFC8080], Sec. 3 [ThisRFC]
3. IANA Considerations
3.1. IANA IPSECKEY Registry Update

Internet-Draft IPSECKEY EdDSA January 2023
3.1.1. Reformat Algorithm Type Field Subregistry
This document requests IANA to add a new field "Format description"
to the "Algorithm Type Field" subregistry of the "IPSECKEY Resource
Record Parameters" [IANA-IPSECKEY]. Also, this document requests
IANA to update the "Description" field in existing entries of that
registry to explicitly state that is for "Public" keys:
Value Description Format description Reference
0 No Public key is present [RFC4025]
1 A DSA Public Key [RFC2536], Sec. 2 [RFC4025]
2 A RSA Public Key [RFC3110], Sec. 2 [RFC4025]
3 An ECDSA Public Key [RFC6605], Sec. 4 [RFC8005]
IANA is requested to update the reference of that registry by adding
the RFC number to be assigned to this document.
3.1.2. Add to Algorithm Type Field Subregistry
Further, this document requests IANA to make 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 the
"IPSECKEY Resource Record Parameters" registry.
Value Description Format description Reference
TBD1 An EdDSA Public Key [RFC8080], Sec. 3 [ThisRFC]
4. Security Considerations
No new issues than [RFC4025] describes.

Appendix A. IPSECKEY EdDSA example
The following is an example of an IPSECKEY RR with an EdDSA public
key base64 encode with no gateway:
foo.example.com. IN IPSECKEY (
10 0 4 . 3WTXgUvpn1RlCXnm80gGY2LZ/ErUUEZtZ33IDi8yfhM= )
The associated EdDSA private key (in hex):
