No joke.  Here's another copy for you to save.  NPR, hmmm?  Did they
mention the part about "The fact of law enforcement access to the
escrowed keys will not be concealed from the American public." ...?

>>                            FACT SHEET
>> 
>>                   PUBLIC ENCRYPTION MANAGEMENT
>> 
>> The President has approved a directive on "Public Encryption
>> Management."  The directive provides for the following:
>> 
>> Advanced telecommunications and commercially available encryption
>> are part of a wave of new computer and communications technology.
>> Encryption products scramble information to protect the privacy of
>> communications and data by preventing unauthorized access.
>> Advanced telecommunications systems use digital technology to
>> rapidly and precisely handle a high volume of communications.
>> These advanced telecommunications systems are integral to the
>> infrastructure needed to ensure economic competitiveness in the
>> information age.
>> 
>> Despite its benefits, new communications technology can also
>> frustrate lawful government electronic surveillance.  Sophisticated
>> encryption can have this effect in the United States.  When
>> exported abroad, it can be used to thwart foreign intelligence
>> activities critical to our national interests.  In the past, it has
>> been possible to preserve a government capability to conduct
>> electronic surveillance in furtherance of legitimate law
>> enforcement and national security interests, while at the same time
>> protecting the privacy and civil liberties of all citizens.  As
>> encryption technology improves, doing so will require new,
>> innovative approaches.
>> 
>> In the area of communications encryption, the U. S. Government has
>> developed a microcircuit that not only provides privacy through
>> encryption that is substantially more robust than the current
>> government standard, but also permits escrowing of the keys needed
>> to unlock the encryption.  The system for the escrowing of keys
>> will allow the government to gain access to encrypted information
>> only with appropriate legal authorization.
>> 
>> To assist law enforcement and other government agencies to collect
>> and decrypt, under legal authority, electronically transmitted
>> information, I hereby direct the following action to be taken:
>> 
>> INSTALLATION OF GOVERNMENT-DEVELOPED MICROCIRCUITS
>> 
>> The Attorney General of the United States, or her representative,
>> shall request manufacturers of communications hardware which
>> incorporates encryption to install the U.S. government-developed
>> key-escrow microcircuits in their products.  The fact of law
>> enforcement access to the escrowed keys will not be concealed from
>> the American public.  All appropriate steps shall be taken to
>> ensure that any existing or future versions of the key-escrow
>> microcircuit are made widely available to U.S. communications
>> hardware manufacturers, consistent with the need to ensure the
>> security of the key-escrow system.  In making this decision, I do
>> not intend to prevent the private sector from developing, or the
>> government from approving, other microcircuits or algorithms that
>> are equally effective in assuring both privacy and a secure key-
>> escrow system.
>> 
>> KEY-ESCROW
>> 
>> The Attorney General shall make all arrangements with appropriate
>> entities to hold the keys for the key-escrow microcircuits
>> installed in communications equipment.  In each case, the key
>> holder must agree to strict security procedures to prevent
>> unauthorized release of the keys.  The keys shall be released only
>> to government agencies that have established their authority to
>> acquire the content of those communications that have been
>> encrypted by devices containing the microcircuits.  The Attorney
>> General shall review for legal sufficiency the procedures by which
>> an agency establishes its authority to acquire the content of such
>> communications.
>> 
>> PROCUREMENT AND USE OF ENCRYPTION DEVICES
>> 
>> The Secretary of Commerce, in consultation with other appropriate
>> U.S. agencies, shall initiate a process to write standards to
>> facilitate the procurement and use of encryption devices fitted
>> with key-escrow microcircuits in federal communications systems
>> that process sensitive but unclassified information.  I expect this
>> process to proceed on a schedule that will permit promulgation of
>> a final standard within six months of this directive.
>> 
>> The Attorney General will procure and utilize encryption devices to
>> the extent needed to preserve the government's ability to conduct
>> lawful electronic surveillance and to fulfill the need for secure
>> law enforcement communications.  Further, the Attorney General
>> shall utilize funds from the Department of Justice Asset Forfeiture
>> Super Surplus Fund to effect this purchase.
