For example, one might want to only use a server-generated key to access the data, in which case this data won't be available offline but will be used to supplement the online behavior. Another might determine the key based on some information in a cookie, which is less secure but does allow offline access while also ensuring that if the cookie changes or is deleted, the data remains secure.

Perhaps we should instead focus on a set of JS Crypto APIs, since that
is largely orthogonal to the storage APIs?
