9. IANA Considerations

[RFC4492], the predecessor of this document, defined the IANA registries for the following:

  • Supported Groups (Section 5.1)

  • EC Point Format (Section 5.1)

  • EC Curve Type (Section 5.4)

IANA has prepended "TLS" to the names of these three registries.

For each name space, this document defines the initial value assignments and defines a range of 256 values (NamedCurve) or eight values (ECPointFormat and ECCurveType) reserved for Private Use. The policy for any additional assignments is "Specification Required". (RFC 4492 required IETF review.)

All existing entries in the "ExtensionType Values", "TLS ClientCertificateType Identifiers", "TLS Cipher Suites", "TLS Supported Groups", "TLS EC Point Format", and "TLS EC Curve Type" registries that referred to RFC 4492 have been updated to refer to this document.

IANA has assigned the value 29 to x25519 and the value 30 to x448 in the "TLS Supported Groups" registry.

IANA has assigned two values in the "TLS SignatureAlgorithm" registry for ed25519 (7) and ed448 (8) with this document as reference. This keeps compatibility with TLS 1.3.

IANA has assigned one value from the "TLS HashAlgorithm" registry for Intrinsic (8) with DTLS-OK set to true (Y) and this document as reference. This keeps compatibility with TLS 1.3.
