This guide explains how to generate a certificate signing request (CSR) for a domain name and all its subdomains with a Web Hosting (excluding free hosting of type Starter).

This allows you to encrypt the connection to your domain name and all its subdomains via SSL.

Set up a Wildcard certificate

1. Add an alias domain with an asterisk *

To add an alias of type * to your website:

1. Click here to access the management of your product on the Infomaniak Manager (need help?).
2. Click directly on the name assigned to the product concerned:
   
3. Click on the chevron ‍ to expand the Domains section of this site.
4. Click on the Add a domain button:
   
5. Enter the domain name to be added in this format:
   • *.domain.xyz (the asterisk is mandatory, followed by a dot, then the domain name of the website which is domain.xyz in this example)
6. Click on the Confirm button to complete the procedure:
   

2. Install an SSL certificate or update it

Example of updating the existing certificate to include the wildcard subdomain *:
