	Title		: Creating 40-Bit Keys for DES
	Author(s)	: R. Housley, P. Hoffman

This document describes an method for shortening DES keys from 56 bits
to 40 bits. The shortened keys are generally known as 'DES-40'. The
motivation for this weakening is that some localities (such as the
United States) give special preference to applications that use 40-bit
keys. The weakened keys are then used with the DES encryption
algorithm in the same manner as full-strength keys.

Send a message to:	mailserv at ietf.org.  In the body type:
	"FILE /internet-drafts/draft-hoffman-des40-01.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
