For years I have used .dmg or .sparsebundle (Encrypted and Password Protected) to safely keep home directory backups on my Mac.
Now, I am looking for a similar Full Permissions/Read/Write that maintains an encrypted, and password protected file that it Tri-Platform. I'd like to have the future ability to use it on Mac OS X, Windows 7/8, and Ubuntu (current releases+).
I appreciate your recommendations. Thank you.
(I like mounting a DMG and having a file directory structure that can be easily maintained and organized. When done, un-mounting the file.)
(I've seen Windows tools to open encrypted DMG files? and I will explore these options, but with the desire to also keep the file accessible on on three OSes, someone might have additional suggestions.)
