This package allows you to generate HTTPS certificates for all your websites in minutes using the free Let's Encrypt service.
All the process is automatic, except for the installation of the generated certificates that will be your responsibility.
Multiple domain names are supported (even for domains not running concrete5), and the certificate renewal can be easily automated (for instance via a one-line script that can be scheduled and must be run as root on the server).
This package also comes with a full set of command line (CLI) commands, so that you can work directly via a shell console - this is useful if you have tons of domain names and/or you have to write files using a different user than the one impersonated by the web server.
Please remark that this is an unofficial package: it's not maintained by Let's Encrypt guys.
NEW IN VERSION 3.0.0: added support to Internationalized Domain Names!
For a list of supported browsers you can visit this page. In just a few words, https certificates generated by this package ave valid for all the more diffused systems, with the exception of Windows XP.
TYPE OF GENERATED CERTIFICATES
Let's Encrypt supports only standard Domain Validation certificates. They don't have plans to support Extended Validation (EV) or wildcard certificates.
