Hi, I'm currently activating Let's encrypt for various already configured websites. This process does not run totally smooth with my installation, therefore I've got one/maybe some questions. First of all: I activated Let's Encrypt for my website domain1.de. This worked fine, I can access the site via HTTPS. In the browser I see that the cert was issued today and is valid until February 3rd. But having a look in /etc/letsencrypt/archive/domain1.de I do not see any key/cert/chain. Where are these files saved to? I would like to use the cert elsewhere too (actually for accessing ISPConfig itself, Postfix, Dovecot...). Thanks!
