Certbot is the new Client from Let’s Encrypt. It’s the successor of the previews letsencrypt-auto Tool. With a simple Webserverconfiguration it’s easy to issue and renew certificates.
ISPs often offer external disk space, together with their server packages, to store several GB of data for backups. Usually this storage space can be accessed via ftp/sftp , nfs or cifs (Samba / Windows shared folder). But that usually means that our data is stored unencrypted on an external server we don’t control.
But there is quite an elegant solution to this using autofs and encfs to automount and encryt that storage space.
