For most browsers and operating systems, yes. See the compatibility list for more detail. Certbot automatically requests certificates for multiple names when requested to do so. The resulting certificates will be accepted by browsers for any of the domain names listed in them. Certbot has added support for wildcard certificates as of version 0. Note that depending how you install Certbotappropriate plugins to automate the process may not yet be available on your system.
Information about the DNS plugins is available in the Certbot documentation. However, certificates obtained with a Certbot DNS plugin can be renewed automatically. There are a large number of other client implementations available too. This website provides information about the level of support for various web servers and operating systems, which varies and is increasing over time.
On supported systems, the automated configuration makes it fast and easy to obtain, install, and automatically renew certificates. If automated configuration is not supported for your web server, you can still get a certificate using Certbot and configure your server software manually. In this case, the certificate will not be renewed automatically.
Note that automated configuration is not required. It can be disabled if you prefer to configure your server software yourself. The webroot and manual plugins work well without root privileges. The certbot-auto script works on the assumption that root privileges will be used, both in order to install OS dependencies where required and because it needs to support all of the plugins mentioned above.
The packaged versions of Certbot are more flexible, and some of the teams building these packages are working toward having Cerbot run with group rather than root privileges where possible.
You can obtain a certificate for an existing CSR, which means you may generate your own CSR using your own private key. However, Certbot will not accept a private key as input and generate a CSR for you. In the future, it may validate from multiple IP addresses at once. They all have their strengths. The Certbot software and documentation are licensed under the Apache 2.

And you may need "RewriteEngine On" before those rules:. And to the question about wildcard certificates, they are supported but only with the help of additional plugins. You're using HTTP validation, where a specific file is uploaded to prove ownership, however this is insufficient for proving that you have ownership of an entire domain.

We reply to it with yes or no. Finally, the prompt will provide a text string. The prompt appears as. The DNS record modification has a propagation delay. Finally, we receive a success message with the certificate location.
It will provide the certificate name, domain name, expiry and certificate location. The certificate is valid for 90 days, therefore, we have to renew it before the expiry. Then, we update the certificate locations in the Apache virtual host. And finally, we reload the Apache to load the new configuration. Later, to automate the SSL renewal process, we add the certbot command in the crontab of the server.

First, a few notes on my setup and versions of certbot. Please read this carefully to save yourself some time. Certbot runs on most flavors of Linux and in this demo, I have used an Ubuntu In order to request wildcard certificates, your certbot client must be version 0. Also note that the method for installing certbot that I am using here will not work in Bash in Windows, so you can save yourself some time by starting a small Linux VM to complete the steps.

The certbot client will walk you through the process of registering an account, and it will instruct you on what to do to complete the challenges. You should see something like:. Before continuing, verify the record is deployed.
How you deploy this TXT record will depend on where your domain is registered. Once you have completed the TXT record, you should verify that it is working using nslookup:. When you have verified that the TXT record is properly deployed, proceed to the next challenge.
Eventually, the certificate will be issued and you should see something like:. To obtain a new or tweaked version of this certificate in the future, simply run certbot-auto again. You will be prompted for a password for the certificate. To deploy an ASE using this certificate, you can use this template. And that is it. You now have a wildcard certificate for your ASE.
