A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the S/MIME Mail Security Working Group of the IETF.

        Title           : Wrapping an HMAC key with a Triple-DES Key or an AES 
        Author(s)       : J. Schaad, R. Housley
        Filename        : draft-ietf-smime-hmac-key-wrap-02.txt

This document defines two methods for wrapping an HMAC (Hashed 
Message Authentication Code) key.  The first method defined uses a 
Triple DES (Data Encryption Standard) key to encrypt the HMAC key.  
The second method defined uses an AES (Advanced Encryption Standard) 
key to encrypt the HMAC key.  One place that such an algorithm is 
used is for the Authenticated Data type in CMS (Cryptographic 
Message Syntax).

NOTE:   The mail server at can return the document in
        MIME-encoded form by using the "mpack" utility.  To use this
        feature, insert the command "ENCODING mime" before the "FILE"
        command.  To decode the response(s), you will need "munpack" or
        a MIME-compliant mail reader.  Different MIME-compliant mail readers
        exhibit different behavior, especially when dealing with
        "multipart" MIME messages (i.e. documents which have been split
        up into multiple messages), so check your local documentation on
        how to manipulate these messages.
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
