Nice, quick implementation. It's cool that it's all client side. People have pointed out the weaknesses as far as non-crushes brute forcing the answer but still this is interesting. I'll have to digest the implications more. I created https://aytwit.com/thoughter which takes the basic idea here to a much more involved extreme. It got some good traction on hackers news a few years ago and I've improved it a lot since then. I still want to make some improvements as far as moving more of the cryptography client-side so people don't have to trust my server as much, yet not ALL client side like this for more convenience and privacy.

Thanks for the submission!
