This blog is now behind CloudFlare

Back in July I registered the domain zhimingwang.org and pointed this GitHub Pages-powered blog at it. Since then I have lost the HTTPS badge due to GitHub Pages not supporting HTTPS on custom domains (see isaacs/github#156).

There have been a lot of discussions on isaacs/github#156 (and stupid +1's too). Among the proposed solutions is putting the website behind CloudFlare. I carefully investigated this option and read almost all the arguments against it. I fully understand CloudFlare's SSL models (summarized in the image below), and I do realize most if not all of the limitations of CloudFlare, including CloudFlare being a huge MITM (which is inevitable for a CDN anyway), as well as most if not all of its annoyances, including CAPTCHAs which I myself would occasionally run into when I'm browsing with PIA VPN, and JavaScript-based browser checks.

CloudFlare's SSL modes. I use the Full SSL mode so that both ends of the connection are encrypted. Again, I know CloudFlare is a big MITM and could be a high profile target. Credit: CloudFlare.

After careful evaluation, I decided that CloudFlare's SSL model is good enough for me. After all, this is just a damn blog, with nothing sensitive. TLS is still nice because it guards against prying eyes and unethical ad-injecting ISPs or Wi-Fi hotspots, but other than that, it isn't necessary.

End result: this blog is now behind CloudFlare. Readers should now see that green HTTPS badge again (note that I'm enforcing HTTPS — without HSTS though). As for CAPTCHAs, I have adjusted the firewall settings on CloudFlare's dashboard — "Security Level" to "Essentially Off" and "Challenge Passage" to 1 year, so hopefully it won't be too annoying.¹

09/01/2016 Update. I just realized that CloudFlare supports whitelisting Tor traffic. Did that.
