The Cryptographic Message Syntax (CMS) specification [RFC5652] defines mechanisms to digitally sign, digest, authenticate, or encrypt arbitrary message content. Many specifications define content types intended for use with CMS. [RFC6031] and [RFC5958] define symmetric key package and asymmetric key package content types that can be signed or encrypted using CMS. CMS allows the composition of complex messages with an arbitrary number of layers. CMS has been augmented by several specifications ([RFC3274], [RFC4073], and [RFC5083]) that define additional mechanisms to enable creation of messages of arbitrary depth and breadth using a variety of authentication, encryption, and compression techniques.

                    Cryptographic Message Syntax (CMS)                    Encrypted Key Package Content Type


   This document defines the Cryptographic Message Syntax (CMS)    encrypted key package content type, which can be used to encrypt a    content that includes a key package, such as a symmetric key package    or an asymmetric key package.  It is transport independent.  CMS can    be used to digitally sign, digest, authenticate, or further encrypt    this content type.  It is designed to be used with the CMS Content    Constraints (CCC) extension, which does not constrain the    EncryptedData, EnvelopedData, and AuthEnvelopedData.
