As a follow up. Is this legal? { Header: <alg:"direct", enc:"AES-GCM"}, IV: ., tag:., payload:. } Or is the line Recipients:[{}], Required? From: Richard Barnes [mailto:rlb@ipv.sx] Sent: Tuesday, July 23, 2013 5:04 AM To: Mike Jones Cc: Jim Schaad; jose@ietf.org Subject: Re: [jose] Question on enc location In which case, it seems like it should be in the top level header, to avoid having it repeated every time. In general, it seems like there are "content" parameters (e.g., enc, zip, cty) that should go at the top level, and "key" parameters that should be per-recipient (e.g., alg, epk, salt). It would be helpful to implementors to be clear about what goes where. On Monday, July 22, 2013, Mike Jones wrote: No - just that the "enc" field for all recipients be the same.
