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
Key
Author(s) : J. Schaad, R. Housley
Filename : draft-ietf-smime-hmac-key-wrap-02.txt
Pages : 8

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).

In the body type:
"FILE /internet-drafts/draft-ietf-smime-hmac-key-wrap-02.txt".
NOTE: The mail server at ietf.org 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
Internet-Draft.
