A New Internet-Draft is available from the on-line Internet-Drafts directories.
Title : The RC4-HMAC Kerberos encryption type
Author(s) : K. Jaganathan, et al.
Filename : draft-jaganathan-rc4-hmac-00.txt
Pages : 22

The Microsoft Windows 2000 implementation of Kerberos introduces a
new encryption type based on the RC4 encryption algorithm and using
an MD5 HMAC for checksum. This is offered as an alternative to using
the existing DES based encryption types.
The RC4-HMAC encryption types are used to ease upgrade of existing
Windows NT environments, provide strong crypto (128-bit key lengths),
and provide exportable (meet United States government export
restriction requirements) encryption. This document describes the
implementation of those encryption types.

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.
