RE: Queries on Message/rfc822, Compressed-Data.

["Pandey, Arun" <arun.pandey@xxxxxxxxxxx>]

 

Hi Russ,

 

As per draft-ietf-smime-x400transport-05.txt to convey information about the contained content

of an S/MIME message in an X.400 transport environment EITs are used.

 

Section 2.5 (2.5.1 to 2.5.6) of draft-ietf-smime-x400transport-05.txt define the EITs for:

1. Enveloped Data

2. Signed Data

3. Certificate Management

4. Signed Receipt

5. Enveloped X.400

6. Signed X.400

 

These match with the corresponding EITs defined in http://www.imc.org/ietf-smime/sm-oid.asn

-- X.400 Encoded Information Types (EIT) for S/MIME objects

id-eit-envelopedData OBJECT IDENTIFIER ::= { id-eit 1 }

id-eit-signedData OBJECT IDENTIFIER ::= { id-eit 2 }

id-eit-certManagement OBJECT IDENTIFIER ::= { id-eit 3 }

id-eit-signedReceipt OBJECT IDENTIFIER ::= { id-eit 4 }

id-eit-envelopedx400 OBJECT IDENTIFIER ::= { id-eit 5 }

id-eit-signedx400 OBJECT IDENTIFIER ::= { id-eit 6 }

 

I am unable to find the corresponding EIT definition for the smime-type parameter

'compressed-data'(CompressedData), that has been newly introduced in the 'draft-ietf-smime-

rfc2633bis-03.txt'.

 

Best Regards

Arun Pandey

These are both discussed in the most recent MSG draft.
Please see draft-ietf-smime-rfc2633bis-03.txt.

Hi,

I had the following 2 queries. Would appreciate a response on these if possible:

1. Going  through the S/MIME mail archive I find a discussion on the use of message types like
    message/rfc822, message/partial etc. that could be used to wrap a protected message (MIME
    content + RFC822 Headers). Also as per MOM of the 54th IETF meeting it seems that
    message/rfc822 message type has been finalized for this purpose.

    My question is how should one distinguish such a message ( A protected message wrapped
    in message/rfc822) from a forwarded message which also has a message type of
    message/rfc822 and can also contain a non protected message? Is an example message of
    type message/rfc822 containing a protected message available for reference?

2. The latest draft 'S/MIME Version 3.1 Message Specification' (draft-ietf-smime-rfc2633bis-03.txt)
    mentions a new S/MIME type "compressed-data". However for this new S/MIME type no
    corresponding EIT has been defined in the S/MIME TRANSPORT draft. Where would one be
    able to find the corresponding EIT for the same?
