Technical Summary

This document specifies a content type for encrypted key packages.  It
is a choice of: EnvelopedData, EncryptedData, or AuthEnvelopedData.  The
rationale for it's use is based on the CMS content constraints
documented in draft-housley-cms-content-constraints-extn.  This document
also defines an attribute that provides a hint as to which key should be
used to decrypt the content when the EncryptedData choice is used.

The specification includes two normative references to I-Ds that will be
published as Informational RFCs (they are currently in the RFC Editor
Queue):
draft-ietf-pkix-new-asn1; draft-ietf-smime-new-asn1.  Both have been
added to the downref registry.

Working Group Summary

Document Quality

The document is short, but provides enough background to explain why why
the content type is needed.
