Cryptographic Message Syntax (CMS) Key Package Receipt and Error Content Types, April 2014
Discuss this RFC: Send questions or comments to firstname.lastname@example.org
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.
