Clipper

   1.  An integrated circuit which
   implements the SkipJack algorithm.  The Clipper is
   manufactured by the US government to encrypt telephone data.
   It has the added feature that it can be decrypted by the US
   government, which has tried to make the chip compulsory in the
   United States.  Phil Zimmerman (inventor of PGP) remarked,
   "This doesn't even pass the sniff test" (i.e. it stinks).
