Howto set all certs on 4096 to get a better score?

I run the script like ./letsencrypt.sh -c

The output:

The certificates generated by this script are using 4096 bit RSA keys by default, the 2048 bit key ist the root CA key which was generated by Let's Encrypt.

Thank you for the reply,

So how can I fix this (not an expert user).
Remove the 2 2048 bit ca keys? How?

Is it in the sh script..

Is it possible to add --rsa-key-size 4096?

@venigo , there is no further action required from your side or this repository owner, everything is working as it should and as you expect.
You can not change anything related to the intermediate cert or ca cert.
Google is your friend to get more knowledge on digital certs.
