I agree, but no one said there were only the two choices - clear or encrypted.  
Because there exists several different levels of encryption, life can still go on if I 
don't have the strongest encryption available.  Certainly stronger is better, but the 
next step down is not plaintext.

Which should have known since I deal with DES and 3DES at work.

I can tell you that all aspects of military crypto are classified.  The algo may be 
public domain, but which one they use is not.

But crypto is used in all levels of government to communicate sensitive data to those 
who need it.  This might include an itinerary for a foreign ambassador, the 
whereabouts of the VP on 9/12/01, the phone number to the oval office (or any office 
at the capitol).  And if there is something in those communiqu�s that can't be 
publicly known, then the algo and/or the key must be protected.  If Joe citizen had 
either or both (the latter is unlikely but not impossible) because he wants to encrypt 
his email to his family, he would then also have an ability to decrypt - or attempt to 
- any government message.  I'd hate to think of the taliban or any other U.S.-hating 
entity having knowledge of an encryption method that can be used against us.

I am not an advocate for government control of encryption, but I believe - as a 
government - I would want to protect my personal and private information from prying 
eyes and Enquiring(sic) minds.  That might mean developing, or seizing control of the 
development of, a very strong encryption and prohibiting its use by Joe citizen, and 
that can be construed as government control of encryption.
