I need to have the certificate key maintained when the certificate is renewed.
In certbot, the equivalent is options --keep and --reuse-key when the certificate is generated, and "reuse-key = true" options in the automatic renewal /etc/letsencrypt/cli.ini file.
I would also like my certificates to use --key-type ecdsa --elliptic-curve secp384r1
How can I do this? Where are the certificate generator configuration files?
Thank you very much.
Bruno.
