It's sad that it only uses a maximum of 256 bits, but I guess it has
to be low enough so that it can be fast enough to be useable. I just
read a rather disconcerting message on bugtraq about 1024 bit
encryption in PKI (ie. pgp/gpg/ssh keys, etc.), and how easily it can
now, conceivably, be cracked. I'll forward a copy to the list for

Yes, I like this. I would *really* like to have something like
~/encrypted and set ~/.ssh and ~/.gnupg as symlinks to that
directory. And if it can be a file instead of an actual partition, so
much the better.
Time to go exploring... =)
