ssl - How to config ssl_trusted_certificate of Let’s Encrypt? -

i use mozilla ssl configuration generator(https://mozilla.github.io/server-side-tls/ssl-config-generator/) generate nginx configuration file.

there item in configuration file, this:

ssl_trusted_certificate /path/to/root_ca_cert_plus_intermediates; 

i use certificate of let’s encrypt,how generate ssl_trusted_certificate ?

this needed when have client certificate verification.

syntax: ssl_trusted_certificate file; default:    — context:    http, server directive appeared in version 1.3.7. specifies file trusted ca certificates in pem format used verify client certificates , ocsp responses if ssl_stapling enabled.  in contrast certificate set ssl_client_certificate, list of these certificates not sent clients. 

i believe not need you, since looking host https site. need comment directive , good.
