Registration of MIME media type application/pkcs8 (possible resubmit)


It's possible that this has been previously brought to this list --  
if so, please slap me around appropriately and point me at the  
review. I was unable to locate it in the mailing list archives.

I'm working through a PROTO writeup on:

http://www.ietf.org/internet-drafts/draft-ietf-sip-certs-03.txt

which contains the following MIME type registration.

---------

    Subject: Registration of MIME media type application/pkcs8

    MIME media type name: application

    MIME subtype name: pkcs8

    Required parameters: None

    Optional parameters: None

    Encoding considerations: The PKCS#8 object inside this MIME type
                             MUST be DER-encoded.

                             This MIME type was designed for use with
                             protocols which can carry binary-encoded
                             data. Protocols which do not carry binary
                             data (which have line length or

As I read RFC 4288, this should say 7bit, 8bit, binary, or framed, not
you have there now.

Is that all that can be said here? For example, doesn't the format
specification have security considerations that could be referenced?

Re: Request for review update of media types audio/3gpp and video/3gpp

Hi,

There has been some minor updates to the media type definition. The 
security consideration section has been updated and some other smaller 
wording changes. We now believe this to be ready to replace RFC 3839. 
Unless there are comments on this before 13th of April we will request 
that IESG approve this registration update.

Re: Request for review of 9 MIME type for 3GPP SA4

Hi,

There was no comments on the latest request. However as I know actually 
intend to take care of these media type registrations I like to ensure 
that no one has any further comment on the current version of the 3GPP 
specification of the media types. The latest version of the 
specification is:

Whole document in Word format:
http://www.3gpp.org/ftp/tsg_sa/WG4_CODEC/Specs_update_after_SA35/26346-730.zip

Media types only in PDF:

Please provide any comments by 13th of April.

Cheers
