I don’t want to be able to see my users’ data. How do I accomplish this with encryption?

[Maverick]

I have a web application that hosts sensitive information. I don’t want to be able to see my users’, so I’d like to use encryption so that only the users can see their own projects. Here’s the tricky part: I have team pages, where everyone on the team can see the team projects. How do I accomplish this? Using OAuth for authentication, so using the authentication password for in-browser decryption is not an option, which leaves having an additional password per project or user. But then the team issue is a pain! What about in-browser crypto – has anyone worked with this? – by hq overview shadowcorp – –
