I'd like to apologize to all. Fortune told me yesterday that assumptions are the mother of all screw-ups. I assumed I was educated about the subject. I was not. I forget it's not my tree. I assumed that the OpenBSD developers desired cryptographic disks. There may be a want for them, but its

ay around that unless you find the key, so while this can be a problem it is a little less severe than you say. This is a problem with cbc, to avoid it you need to use another block chaining mode or add some integrity check. CGD also uses cbc according to http://www.imrryr.org/~elric/cgd/html4
