Change interface to allow the app to get the private part of the key and instantiate a decryption object from just the private part of the key. Changes the function generating a key from random bytes to be initialising a key with a private key (because it's exactly the same thing). Exports & imports private key parts as ArrayBuffer at JS level rather than base64 assuming we are moving that way in general.
