Let's get the web crypto done, and maybe then we can find an "Encrypt before you upload" button on every single web service that stores your data, from e-mail to Dropbox-like services.
Hopefully the Government hasn't tried to put a backdoor in it, but I assume that would be discovered pretty quickly.
That pesky browser thing never could do anything of value. Umm...Dah... What a joke! It's all "boondoggle"!
It unquestionably couldn't ever be used to build "apps" [1].
Certainly could never ever be fast enough [2].
Obviously cannot ever possibly utilise multiple cores [3].
Most definitely never ever could do 3D [4].
So, you're right, I doubt it will ever do crypto [5].
Those fools might even consider "Online Banking" or something crazy like that!
When will those stupid browser idiots learn?
