Generating a certificate (CSR) for all subdomains of a domain name (Wildcard)

This guide explains how to generate a certificate request (CSR) for a domain name and all its subdomains. This will let you encrypt the connection to your domain name and all subdomains using SSL.

Please note that this procedure is also valid for Let's Encrypt certificates.

Setting up a Wildcard certificate

1. Open the Manager (manager.infomaniak.com)
2. Go to Web Hosting
3. Click on the hosting/domain name in question
4. Under Sites,  in the the lower right corner, click on Add a site and click Add
5. In the alias Domain Name to be added field (one per line), enter *.your-domain.com
6. Hit Save

When generating a certificate request (CSR), it is now possible to select *.your-domain.xyz
