"encryptAndWrite" and other functions do not throw error even error occurs during the process

[nakaakist]

In encryptAndWrite function, errors during the encrypting & writing process are all caught, and returned as string.

However, this behavior is confusing because the document says that the return value of this function is the created stream ID.

How about just throwing error when error occurs? It would reduce confusion, and also would help developers easily debug their apps.

(fyi: we use this function in our app, we had to write a bit ugly error handling due to this behavior.)
