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 cryptography (128-bit key lengths),
and provide exportable (meet United States government export
restriction requirements) encryption.  This document describes the
implementation of those encryption types.  This memo provides information for the Internet community.
