I read now about a nice cloud service that keeps security and privacy, called Wualy from lacie. It's possible to store up to 5gb of stuff. I don't represent them.

The beauty is that everything is encrypted on your computer/device and then uploaded to the cloud.
They also have tar.gz versions.

Quote:
Wuala employs the 256 bit AES, 2048 bit RSA and SHA-256 algorithms for encryption, signatures and integrity checks. If you're interested in how Wuala manages encryption, have a look at our publication on Cryptree.


The link is here:
http://www.wuala.com/en/learn/technology

Looks very promising, although I didn't check it.

Enjoy. if someone checks, please post your comments.

queen,

AFAICS this is a blob without the source code available.
That means that you don't know what the software does.
It's impossible to review their claims about encryption, signatures and integrity checks without decompilation.
To me that's not trustworthy.
It's exactly as good as skype, just the claims are a bit different.
In case I would use the services of a cloud storage provider, which I don't, I'd choose one that has an open source client or, preferably, uses a standardised protocol and I'd do the encryption locally on my own before uploading.

The point is not at all on the software that encrypts, but the software that sits between the encryption function and your data/the keys.
Without the sourcecode to that you don't know what happens to your data/keys.

Yes, you are right.

However, there is source code of wualawebstart.
http://wualawebstart.cvs.sourceforge.net/viewvc/wualawebstart/wualawebstart/loader/com/wuala/loader2/

and see also the crypto folder.
http://wualawebstart.cvs.sourceforge.net/viewvc/wualawebstart/wualawebstart/loader/com/wuala/loader2/crypto/

If you open the tar.gz you will see a file called loader3. So something exists, although not completely.

That's good. To be honest I didn't expect that.
The code would have to be reviewed to judge whether the whole thing is trustworthy or not, which I doubt.
