Payara Server And Letsencrypt

[musterio]

Hello all,

I was trying to make my website secured using letsencrypt (certbot) ssl certificates, it took me a while to cover the script of installing the certificates into the payara server from certbot covering all https certificates needed. You can follow this post in letsencrypt forum for more information: https://community.letsencrypt.org/t/importing-letsencrypt-into-java-and-glassfish/9711

Would there be a wizard maybe to install letsencrypt ssl script through payara admin so i don't have to go through all these details in the script in order to install the https certificates for my webserver?
Beside that there is a weakness in my ssl installation that mark the website with grade B from this link: https://www.ssllabs.com/ssltest/ . The website i am using is https://www.ppollweb.com.
The reasons for this mark are as the following:
* This server supports weak Diffie-Hellman (DH) key exchange parameters
* The server does not support Forward Secrecy with the reference browsers

What should be done through payara admin to fix these issues?

Thanks and regards
