  The only reason for this is US export laws.

  Here are the ones I have:

     DES-ECB OBJECT IDENTIFIER ::= { algorithm 6 } 
     DES-CBC OBJECT IDENTIFIER ::= { algorithm 7 } 
     DES-OFB OBJECT IDENTIFIER ::= { algorithm 8 } 
     DES-CFB OBJECT IDENTIFIER ::= { algorithm 9 } 
     DES-MAC OBJECT IDENTIFIER ::= { algorithm 10 } 
     DES-EDE OBJECT IDENTIFIER ::= { algorithm 17 }

     where 

     algorithm OBJECT IDENTIFIER ::=  
       {iso(1) identified-organization(3) oiw(14) secsig(3) algorithm(2)}
