I know in Lion that you can get FDE but that's not what I am after. I have a small set of files which I access infrequently but need to keep secret. I know you can set up an encrypted disk image with Disk Utility but I was wondering what the best settings are for my use. I would like for the encrypted partition to be accessible from another machine (possibly windows, possibly linux) if my mac breaks. Ideally I would like the image to be expandable to fit the contents, but only take up the space it requires on the disk (dynamically expanding). Is this possible, if so which settings do I use? Thanks.
