5.  IANA Considerations

   For each of the private-key information content types defined in
   Section 2, IANA has assigned an Object Identifier (OID).  The OIDs
   for the content types have been allocated in the "SMI Security for S/
   MIME CMS Content Type (1.2.840.113549.1.9.16.1)" registry
   [IANA-CMS-CTS] as follows:

            +=========+==========================+===========+
            | Decimal | Description              | Reference |
            +=========+==========================+===========+
            | 52      | id-ct-privateKeyInfo     | RFC 9939  |
            +---------+--------------------------+-----------+
            | 53      | id-ct-encrPrivateKeyInfo | RFC 9939  |
            +---------+--------------------------+-----------+

                                 Table 1

   For the ASN.1 module in Section 3, IANA has assigned an OID for the
   module identifier.  The OID for the module has been allocated in the
   "SMI Security for S/MIME Module Identifier (1.2.840.113549.1.9.16.0)"
   registry [IANA-SMIME-MODS] as follows:

             +=========+=========================+===========+
             | Decimal | Description             | Reference |
             +=========+=========================+===========+
             | 85      | id-mod-pkcs8ContentType | RFC 9939  |
             +---------+-------------------------+-----------+

                                  Table 2

   IANA has updated the application/cms registration entry in the "Media
   Types" registry by adding RFC 9939 to the "Interoperability
   considerations" section and to the list of RFCs where Inner Content
   Types (ICTs) are defined (see the "Optional parameters" section) and
   by adding the following values to the list of ICTs:

   *  privateKeyInfo
   *  encrPrivateKeyInfo

   IANA has also updated the "Security considerations" section in the
   application/cms entry as follows:

         +==========+============================================+
         | RFC      | CMS Protecting Content Type and Algorithms |
         +==========+============================================+
         | RFC 9939 | privateKeyInfo and encrPrivateKeyInfo      |
         +----------+--------------------------------------------+
