I use Mozilla SSL Configuration Generator
(https://mozilla.github.io/server-side-tls/ssl-config-generator/) to generate a nginx configuration file.
There are three items about certificate,as follow :
ssl_certificate /path/to/signed_cert_plus_intermediates;
ssl_certificate_key /path/to/private_key;
ssl_trusted_certificate /path/to/root_CA_cert_plus_intermediates;
I use certbot(https://github.com/certbot/certbot) to apply certificate,but I can not find ssl_trusted_certificate
,how to generate it ?
