<p>Certbot is usually meant to be used to switch an existing HTTP site to work in HTTPS (and, afterward, to continue renewing the site’s HTTPS certificates whenever necessary). Some Certbot documentation assumes or recommends that you have a working web site that can already be accessed using HTTP on port 80. That means, for example, that if you use a web browser to go to your domain using http://, your web server answers and some kind of content comes up (even if it’s just a default welcome page rather than the final version of your site). Some methods of using Certbot have this as a prerequisite, so you’ll have a smoother experience if you already have a site set up with HTTP. (If your site can’t be accessed this way as a matter of policy, you’ll probably need to use DNS validation in order to get a certificate with Certbot.)</p>

To use certbot --standalone, you don’t need an existing site, but you have to make sure connections to port 80 on your server are not blocked by a firewall, including a firewall that may be run by your Internet service provider or web hosting provider.

<p>A server is a computer on the Internet that provides a service, like a web site or an email service. Most web site owners pay a hosting provider for the use of a server located in a data center and administered over the Internet. This might be a physical dedicated server, a virtual private server (VPS), or a shared server. Other servers provide other parts of the Internet infrastructure, such as DNS servers.</p>

<p>SSH (which stands for “secure shell”) is a technology for connecting to a remote server and accessing a command line on that server, often in order to administer it. The administrator of a server can grant SSH access to others, and can also use SSH access directly in order to administer the server remotely. SSH is usually used to access servers running Unix-like operating systems, but your own computer doesn’t have to be running Unix in order to use SSH. You normally use SSH from your computer’s command line in a terminal by typing a command such as ssh <a href="mailto:username@example.com">username@example.com</a>, especially if your own computer runs Linux or macOS. After logging in, you’ll have access to the server’s command line. If you use Windows on your computer, you might also use a dedicated SSH application such as PuTTY.
Most Certbot users run Certbot from a command prompt on a remote server over SSH.</p>

<p>A wildcard certificate is a certificate that includes one or more names starting with <code>*.</code>. Browsers will accept any label in place of the asterisk (<code>*</code>).
