Subject: --- lock ---

From the algorithm described, I would assume that locking twice, with
different keywords could be undone, using the same two keywords IN
REVERSE ORDER (i.e.: if locked with "dead" then "bolt", unlock with
"bolt" first then "dead"....)   It MIGHT work unlocking with "dead"
then "bolt"....but I wouldn't want to bet on it.....  BTW:  can
you "unlock" a file that has not been locked....if so, can you recover
the data (perhaps  by "locking" it?).
