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

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
