I have now installed a better #SSL
certificate issued by #LetsEncrypt
and with the help of this #python
Plus I have used a largely expanded #shell
But now my SSL sites got rated with B by #SSLLabs
because of an incomplete chain. I think I need to download the CA certificate and attach it at mine?
I also have (not yet reloaded) added DH parameters (DH = Diffie-Hellmann?) to my certificate parameters, I have read it will improve some security.
