7. IANA Considerations​

IANA has registered a new value in the "TLS Certificate Types" subregistry of the "Transport Layer Security (TLS) Extensions" registry [TLS-Ext-Registry], as follows:

  • Value: 2
  • Description: Raw Public Key
  • Reference: RFC 7250

IANA has allocated two new TLS extensions, client_certificate_type and server_certificate_type, from the "TLS ExtensionType Values" subregistry defined in [RFC5246]. These extensions are used in both the client hello message and the server hello message. The new extension types are used for certificate type negotiation. The values carried in these extensions are taken from the "TLS Certificate Types" subregistry of the "Transport Layer Security (TLS) Extensions" registry [TLS-Ext-Registry].
