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?

Good luck ...

I hope you find what you're looking for, but I would suggest that:

This isn't possible.

Unless you own the crypto bits, and you know for a fact that they don't have any way to access your keys, you should assume any provider can probably comply with court orders and hand over your data.

Some of them might be peaking even if they claim not to be.

The only way you can be guaranteed your stuff is secure is to encrypt it yourself, and cut the cloud out of the process entirely.

There pretty much is no such thing as "trustworthy encryption" you didn't do yourself.
