PPAPI support for Chrome

Google has discontinued NPAPI support, WebPG is not working on latest Chrome browser in our Linux boxes.
Are you planning to implement PPAPI for Chrome compatibility?
thanks in advance

While PPAPI would be the desired route, as I understand it, PPAPI (without Native Client - "NaCl") is not a viable option. My understanding is that PPAPI plugins (without NaCl) have no mechanism in which to install them. The issue with providing a PPAPI plugin with NaCl is the very restrictive sandbox (no fork, exec, etc.) and lack of ability to call, pipe or otherwise interact with an external binary/library (no way to communicate with GnuPG). If the above statements are ill-informed, I would love to hear about.

In the meantime, I have reluctantly changed the architecture in order to support "Native Messaging", which is a "messaging host" (binary) that is registered within chrome via a manifest (and registry key in windows), and communicates via STDIN/STDOUT.

The project kylehuff/libwebpg is actually used by webpg-npapi, and it provides the abstracted GnuPG methods, and webpg-npapi provides the NPAPI portion. kylehuff/libwebpg can be compiled as either a binary or library, which provides support for both Native Messaging (binary) and Mozilla's JS-CTYPES (library).

I plan to actually publish this information in the libwebpg wiki, however I have been left scrambling to react to the fact that Native Messaging has no in-built mechanism to install or bundle the "host" into the host operating system; that would require an external, out-of-band installer (which has crippled one of my projects that uses used webpg-npapi in chrome).

Some information about native messaging can be found here: https://developer.chrome.com/extensions/messaging#native-messaging

And my arguments/disdain regarding the Native Messaging implementation has been noted here: https://code.google.com/p/chromium/issues/detail?id=321628#c26

I should note, kylehuff/libwebpg is currently under heavy testing, and I have a few hundred lines of changes that are pending (not yet committed). I hope to have the improvements/fixes pushed out this weekend.

Apparently the markdown was not working all that great, by kylehuff/libwebpg I mean https://github.com/kylehuff/libwebpg
