Thanks for the answer, but I was meaning from your customer perspective. My understanding is that you offer a key-value store, so the only operation available on the encrypted data is a comparison (==).

If my application wants to retrieve data within a certain range (< and > operators) is there anything I can do to implement it on top of you SDK?

Think of the encrypted messages app: how can I retrieve this month's messages using your SDK?

I hope this clearer now...
