Whazzup,
I just released the beta of my plugin that implements OpenPGP into
Roundcube through JavaScript by using the OpenPGP.js library. Github
repo available here
and announcement here.
Expect a stable release as soon as I have regulated my dopamine
levels; or rather, as soon as I have fixed these
minor issues. I'm estimating it'll take at most one or two
weeks to finalize the stable version. In the meantime we can handle
the political discussions that this may stir up.
Please ennjoy it, mah homiez!
