Finally, I managed to enable HTTPS on my own blog!
I opted for a quick-and-dirty solution based on a self-compiled version of HAProxy in front of WordPress, statically linked to OpenSSL 1.0.2, in order to serve Certificate Transparency information during the TLS setup.
The recent OpenSSL 1.0.2 version added support for Certificate Transparency (CT) RFC6962 by implementing one of the methods that allow TLS clients to receive and verify Signed Certificate Timestamp during the TLS handshake, that is the OCSP response extension. My goal here is to show how to use another method, the signed_certificate_timestamp TLS extension, to gain the same result.
