                   Cryptographic Message Syntax (CMS)
              Key Package Receipt and Error Content Types

Abstract

   This document defines the syntax for two Cryptographic Message Syntax
   (CMS) content types: one for key package receipts and another for key
   package errors.  The key package receipt content type is used to
   confirm receipt of an identified key package or collection of key
   packages.  The key package error content type is used to indicate an
   error occurred during the processing of a key package.  CMS can be
   used to digitally sign, digest, authenticate, or encrypt these
   content types.

1.  Introduction

   This document defines the syntax for two Cryptographic Message Syntax
   (CMS) [RFC5652] content types: one for key package receipts and
   another for key package errors.  The key package receipt content type
   is used to confirm receipt of an identified key package or collection
   of key packages.  The key package error content type is used to
   indicate an error occurred during the processing of a key package.
   CMS can be used to digitally sign, digest, authenticate, or encrypt
   these content types.

1.1.  Requirements Terminology

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
   document are to be interpreted as described in [RFC2119].

1.2.  ASN.1 Syntax Notation

   The content types defined herein use ASN.1 ([X.680], [X.681],
   [X.682], and [X.683]).

   The CONTENT-TYPE definition was updated to the 2008 version of ASN.1
   by [RFC6268]; however, none of the new 2008 ASN.1 tokens are used in
   this specification, which allows compilers that only support the 2002
