RE: S/MIME and X.400

Hi Vijay,

        You should see the I-Ds draft-ietf-smime-x400wrap-04 and 
draft-ietf-smime-x400transport-03.  In brief, x400wrap describes wrapping X.400 
content types inside a CMS object, and x400transport describes conveying a CMS 
object over an X.400 transport system as an X.400 content type itself.  Except 
in the case of a forwarded message, CMS objects are not embedded in X.400 
content.

        In ASN.1 terms, a CMS 'ContentInfo' object is plugged into the X.400 
'content' field in X.411.  The content is identified in the 'content-type' 
field by either of the following OID values depending upon whether or not it is 
MIME encoded.

        id-data OBJECT IDENTIFIER ::= { iso(1) member-body(2) us(840)
        rsadsi(113549) pkcs(1) pkcs7(7) 1 }

        id-ct-contentInfo  OBJECT IDENTIFIER ::= { iso(1) member-body(2)
        us(840) rsadsi(113549) pkcs(1) pkcs-9(9) smime(16)
        content-types(1) 6}

The x400wrap draft mainly specifies some specific uses of options in CMS 
appropriate to X.400 content.

        Plz let me know if I can answer any more questions.

Hello,
        
        I have an application where in I have to build an X.400 message. The
"Content" of the message would be a CMS object. How do I insert a CMS object
into the  X.400 Content ?
        alternatively,  How will such a message look like in ASN.1 form ? 


Thanks in advance,
Vijay Hegde
