Encryption in Lion and Windows

[Cheetah05]

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.

Sounds like you are ready for something like Espionage.

I'd rather not buy anything as I am sure this can be done for free.

Try Truecrypt, from truecrypt.com. It's an excellent product. It creates an encrypted volume of any size you chose, and you can store your secret files there. The volume is actually a file and can be given any file name.
