] BAGHDAD, Feb. 9 -- Insurgents in Iraq sought the help of
] senior leaders of the al Qaeda terrorist network for a
] plan to spark a "civil war" that would pit the country's
] religious and ethnic groups against each other and
] prevent a transfer of sovereignty from U.S. occupation
] authorities to Iraqis, U.S. officials said today, citing
] a document seized from an al Qaeda courier.
  . . .
] The document was on a computer disk that was found in a raid
] on a terrorist safe house in Baghdad about a month ago,
] officials said.

I'm curious whether or not it was encrypted, and if so, how.
