I've got a few boxes running testing/unstable and I'd like to test running encrypted filesystems on some of them.
My question is if it's possible to set up a pre-existing reiserfs or ext3 filesystem for encryption. From what I've seen, it's more or less mounting it as loopback with losetup but it appears you've got to set up the encryption before creating the filesystem. Is it typically best to use the 'AES' encryption with a extremely long pass phrase, BTW? Thanks in advance, Bill PS: Will this ever be an option available at install time (or is it already and I just missed it?)
