I guess at this point I should chime in.

I have been working on adding streaming support for openpgp.js encrypted messages containing files. [1] [2] I mimics the node.js stream API [3] so it's largely compatible with "the rest of the world's software". To get an idea of how it works you should look at the unittests [4] [5]. Basically you write to a MessageStream instance chunks of your file and it will emit "data" events with chunks of encrypted data including all the headers for the various data structures inside a OpenPGP Message [6]. If you prefer to just encrypt using AES in cfb mode you can also use the streamed CipherFeedback [7], that works similarly [5]. I need to fix up some things that ~tanx pointed out in the pull request comments [2], though the API will not change so you can start trying it out and you will not have to change the code once I make these changes. In the end this is something that I am doing to integrate jquery-file-uploader and openpgp.js. You can see the relevant jquery-file-uploader patches I wrote in this branch [8]. Let me know what you think. ~ Art.
