Yes, that should work fine. Just make sure k >= 128 (or whatever level
of protection is desired) and use appropriate padding. If the all-or-nothing
transform is fast enough (and secure, of course), it should be a lot faster
than doing RSA on the whole thing. Let's patent it: "Gillogly & Anonymous
1999"... just in time for the RSA going-away party. Shall we cut Ron in for
a piece of the action? :)
