What is linode certbot wildcard?

When using Certbot on a Linode VPS to get a wildcard certificate, we can take he following steps:

1. Certbot may be installed on a Linode VPS using the Linux distribution’s command line package manager.

   In Ubuntu, for example, we can install Certbot with the command sudo apt-get install certbot.
2. Get a wildcard certificate: To obtain a wildcard certificate, enter the domain name for which we need the certificate. This includes the asterisk (*) character to indicate the wildcard subdomain.

   To acquire a wildcard certificate for the domain example.com, for example, type sudo certbot certonly —manual -d ‘*.example.com’.
3. Perform the DNS challenge: Certbot will ask us to complete a DNS challenge to prove that we hold the domain for which we are seeking the certificate.

   This entails adding a TXT record to the domain’s DNS settings. To complete this stage, we will need to follow the instructions supplied by Certbot.

4. Install the certificate: After completing the DNS challenge and receiving the wildcard certificate, we may install it on the Linode VPS.

The specific procedure for installing the certificate will be determined by the web server software being used (e.g. Apache or Nginx). The Certbot manual contains steps for deploying the certificate on various web servers.

We can use Certbot to get a wildcard SSL/TLS certificate for the Linode VPS by following these instructions. This enables us to protect an unlimited number of subdomains for the domain with a single certificate, resulting in increased security for the website or application.
