# Files of a Certificate The acme client recommends not to use the acme storage directly but to copy the needed files into a wanted structure. After issue or renew a certificate with acme all files you need on the target system will be copied from acme to a certificate directory. ## Target dir see ./inc_config.sh ... the target directory is set with ```sh export CM_diracme="./certs" ``` ## File structure The certificate folder contains the fqdn as directory and in it are the files: ```txt ./certs/ +-- www.example.com/ +-- www.example.com.ca.cer +-- www.example.com.cert.cer +-- www.example.com.fullchain.cer +-- www.example.com.haproxy.pem +-- www.example.com.key.pem ``` Here are the files from acme client * the key * the server certificate * the intermediate certificate * a chained certificate (server + intermediate certificate) * the ca certificate For Haproxy a 2nd chained certificate will be generated.
