Install elixir (>= 1.9) and then run ./entrypoint.sh.
On the first launch the program will generate two file. ca.pem and ca_key.pem.
You will need to install ca.pem as a root certificate in your system or application (Firefox for example).
After that set https_proxy to 127.0.0.1:8080 and then you will be able to bypass censorship based on SNI sniffing.
Keep in mind that we do not send the SNI correctly, So the webserver won't send us the correct certificate hence the validation of server certificate is not possible (easily!). I wouldn't recommend logging in or sending sensitive information with this approach.
Also some services are censored by their server's IP Address. In this case bypassing SNI won't help.
