   I don't recall from
   the DES algorithm whether the key schedule is uniquely invertible to the
   key, but even if it is, it is considerably more work than snatching the key.

But if you have the key schedule you don't need the key at all!  (Jeff
thought of this right off the bat.)  pcbc_encrypt doesn't even take the
key as an argument, it only takes the key schedule.  So I don't think
the protecting the master key argument flies ...
