OT Maybe: Crypto for Lin/Win

[Jason Pfingstmann]

Does anyone know of any methods of loopback file encryption which works 
both in the Linux world and the Windows world?  Preferrably one that is 
expandable/shinkable.  I currently use loopback patched with encryption 
support and aes256, but I don't think I can start anything with this 
loopback file in Windows.  I did however, discover that since it does 
encryption by the block, I could actually add space to the end of it and 
use a resize tool for the FS to expand it.  I'd like to find something 
that works in Windows too, though.
