Ask Slashdot: Keeping Cloud Data Encrypted Without Cross-Platform Pain?
bromoseltzer writes: I use cloud storage to hold many gigs of personal files that I'd just as soon were not targets for casual data mining. (Google: I'm thinking of you.) I want to access them from Linux, Windows, and Android devices. I have been using encfs, which does the job for Linux fairly well (despite some well-known issues), but Windows and Android don't seem to have working clients. I really want to map a file system of encrypted files and encrypted names to a local unencrypted filesystem — the way encfs works. What solutions do Slashdot readers recommend? Ideal would be a competitive cloud storage service like Dropbox or Google Drive that provides trustworthy encryption with suitable clients. Is there anything like that?
If you get rid of the mobile requirement, http://mega.co.nz/ might be the solution for you.
Specifically designed by Kim Dotcom's folks so that they CANNOT access your data (so they don't tell if you've got financial paperwork or pirated movies). Has a method for sync'ing a local unencrypted filesystem into their cloud architecture.
