Cryptography is hard to get right: there is a companyin Russia called
Elcomsoft that makes a tidy income selling cracks for the password
"protection" in Intuit QuickBooks.

Put the entire folder that's got your .gnucash file on a TrueCrypt volume:

   http://www.trucrypt.org/

There are two ways to do it.  One is a "virtual disk", in which a
regular file is encryped, then formatted with a filesystem and mounted
like a regular drive.  The other way to do it is to encrypt a physical
partition on a real drive.

TrueCrypt also supports full-system encryption for Windows, with
boot-type password entry.

If you use encryption, be very very careful to maintain regular
unencrypted backups, and *test* your backups from time to time to
ensure you can really restore them.  It's not just that you might
forget the password, but that something might happen to incapacitate
you so that no one would be able to manage your affairs on your
behalf, or should your encrypted volume get the slightest little
corruption, so much as a single flipped bit, it will be totally
unrecoverable.

I'll send you my bill in the mail.
