Or you could slap a header on the front that makes it look like it is
encrypted with a decent (but brute forceable) cypher.   Some news
reports have suggested that "they" are permanently storing everything
that is encrypted for possible future decryption.   Get all your
friends to do this and then buy stock in companies that sell archival
storage systems.   Fill up the silos with plenty of hay and they may
never have the resources use wholesale decryption to find the actual
needles in those hay stacks of S/MIME or PGP "encrypted" messages.
