AFAICT, for this use case, we just need a simple API that says "store this data encrypted with assurance level <X> of confidentiality, requiring assurance level <Y> of authentication to unlock, and restricted to content from origin <Z>" similar to what Microsoft Exchange does for mobile devices. 

Even if you had an explicit crypto API, you would need the above API anyway, for protecting the keys, right?
