  JA3 is a standard for creating SSL client fingerprints in an easy to produce and shareable way.

  

This paper is nice, but it goes over some finer technical things.

So, not about the great wall, but there's projects out there, like this one https://github.com/salesforce/ja3 , which talk about how you can fingerprint fully encrypted traffic. Would be surprising if the great wall doesn't do this, when some open source firewall will.

  An unidentifiable mechanism that helps you bypass GFW.

  

A fellow Aussie currently in China, a Trojan [0] server has been working fine for the last week I've been here. I've got it hosted through a VPS (smaller provider) in LA. While it's a bit of a pain to setup, reliability has been rock solid and definitely useable - my laptop is connected 24/7 and I can access the unfiltered web, including video, just fine. V2ray also supposedly works quite well, but I haven't looked into it.
