I thought of that as well.  Putting the key on a CD and having that in
only when it's needed would be good, too, but pretty inconvenient in a
remote server environment.

Right.

My next approach is a get a [pgp?] passphrase from the user and cache
that in memory but not save it in the backups; then the hacker would
have to get at the running system to see where in memory to dump.  On
the other hand, it's only as safe as the employees using the passphrase;
an improved approach is to tie it to the account used for access -- but
now we're getting more into the system side than the database side, which
may not be interesting to the list ;-)

Of course not :-)  They have to come together somehow, though, and that's
the trick.


Thanks! & HAND
