Creating an SSL Certificiate
Please follow the steps below to create a new SSL certificate on ZeroSSL. Before you start, please note that you can choose from single-domain, multi-domain and wildcard certificates with a both 90-day or 1-year validity.
Step 1: Enter Domain(s)
To create an SSL certificate, navigate to the New Certificate page and get ready to enter the domain(s) you want secured. You can enter a single domain or multiple domains, or choose to protect your domains using a wildcard certificate.
- Single-Domain Certificate
Secure a single domain using your SSL certificate. For single-domain certificates, the www-version of your domain will be secured as well at no additional charge.
- Multi-Domain Certificate
Secure multiple domains using your SSL certificate. You can both add multiple versions of the same domain (e.g. www-version or subdomain) as well as completely unrelated domains (e.g. apple.com and store.com).
- Wildcard Certificate
Secure all subdomain versions of your dumain using your SSL certificates. Wildcards are typically shown as *.domain.com in order to represent that any type of subdomain is protected at once.
Step 2: Choose Validity
Next, you will need to choose between a 90-day or 1-year validity for your SSL certificate. To keep manual work renewing certificates at a minimum, we usually recommend choosing 1-year certificates.
- 90-Day Certificate
SSL certificates with a validity of 90 days. For this type of certificate, manual renewal will be required every 90 days.
- 1-Year Certificate
SSL certificates with a validity of 1 year (365 days). For this type of certificate, renewal will be required once per year.
