Ask HN: Where is our zero knowledge cloud?

15 points by coopdog 13y ago ↗ HN

Browser based public/private key encryption, for a true 'cloud' communication experience.

Public keys linked to web persona's (anonymous or not), so you can easily select recipients of the message (email, chat, file, photo gallery, etc). The message is encrypted twice, once as just a summary (because it's the cloud, we browse but don't download everything), and one with the actual data.

The server stores the messages, the recipients decrypt in the browser with a private key stored on one of their USB sticks and accessed through the HTML5 file system API.

Is it an idea who's time has come?

We already had such a thing, in essence, except there were no takers. [1] Implemented by a bright HNer. [2]

The problem is doing meaningful processing on the data without exposure to the server, including indexing, search, etc.
