Hi,
one thing I don't understand: Storing your files in cloud has one and only purpose: To access them from other computers over the internet. You do not upload your files just to save them, at least not to a public provider, that would be cranky, wouldn't it? You upload them to access them from anywhere and therefore you prevent your provider from reading them. That's the internet.
So that does mean that you need a way to decrypt your data on strange computers, e.g. in an internet cafe or in the office, and that you cannot and do not want to install any software on these computers. I've flown over the headlines of the first 15 pages of discussions - and this problem isn't even mentioned. Nor in the support docs of manufacturer, at least this is not mentioned there as the first and most important feature. What's going on? Why does one upload his data, if he cannot access them over the internet without primarily searching someone to install decryption software on that computer (whether in the office or wherever)? You don't upload your files just to download them to the same computer, don't you?
Thanks for your ideas, or even better, for a solution to use the cloud in a useful and safe manner.
Regards,
Stefano
