Are there any web servers supporting RFC8879 TLS Certificate Compression?

I am trying to verify an implementation of RFC8879. Are there any webservers or TLS libraries which have implemented this RFC? I have done some research and my results indicate that the popular webservers/tls libraries have not implemented this RFC yet.

I'm aware the Chrome browser supports certificate compression in their ClientHello (brotli), are there any servers which support this in their ServerHello? It doesn't seem like google's servers are responding with a CompressedCertificate message.

Solution

  • Yes: LiteSpeed Web Server supports certificate compression.

    From 5.4 release notes:

    • [NEW FEATURE] HTTPS certificate compression, reducing the size of HTTPS handshake exchange data.
