Dear All,
This is in response to ACTION-856 (Discuss possible encryption algorithms suitable for streaming).

In my opinion, GCM would work well also for streaming. One can easily do a "chunked" form of GCM wherein each chunk being whatever size is deemed optimal for the streaming situation, having its own authentication vector, and using the nonce as a counter to ensure no lost (or re-ordered) chunks. One could also have a special indicator for the last chunk.
