Dude, I was here to talk about security, not to be judged on the quality of my English. What I get from your take is that your English is better than mine, but not your security knowledge.

> That isn't what "sandboxed" means, it has nothing to do with checking hashes.

I didn't say it had anything to do with it. I meant that NOT ONLY it is sandboxed, but ON TOP OF THAT you can check that you received the same code.

> You keep referring to "backdoor", and I don't think you really know what that means.

The only explanation I see for you not understanding what I mean by "backdoor" for the end-to-end encryption is that you have no idea how it works. If you're just being condescending about my language, go for it. Tell me I can't speak your language. But don't tell me I don't understand security, you have absolutely no idea what I know.

> Protonmail sending a "web page" that "leaks your key"? WTF?

You obviously don't understand how it works if this surprises you. I would gladly elaborate with anyone who is not a jerk, but that does not seem to be the case here.
