[openpgp] On Streaming and Chunking

2015-03-24 07:25:57
Adam's post on streaming API's has been posted before:
https://www.imperialviolet.org/2014/06/27/streamingencryption.html

The same problem is the root cause of the Java GCM CipherInputStream
issue: 
http://blog.philippheckel.com/2014/03/01/cipherinputstream-for-aead-modes-is-broken-in-jdk7-gcm/

But I haven't seen any discussion of Adam's point that one _can_
construct a format for chunking and authenticating the chunks (and
ordering thereof) to provide authenticated streaming. And that someone
has already done so:
https://github.com/kaepora/miniLock#4-file-encryption

I think support for a mode like this would be good to consider, and I
think if IPR allows it, a fully-specified design for it is a good
place to start.
