How to get an 1-year free SSL certificate from Aliyun?

admin

Original Digicert Free Single Domain Certificate, recommended for testing and personal use scenarios, org and jp domains may not be eligible due to special domain names, it's recommended to use paid certificates in official environments. Each real entity (individual or enterprise) can receive 20 free single domain trial certificate quotas per year. Additional payment is required if more than 20 certificates are needed. The free single domain trial certificate will automatically clear expired quantities on the last day of each year (December 31 at 24:00). The free single domain trial certificate does not support re-subscription and cannot be topped up with old certificates' expiration time. The SSL certificate provided by Aliyun only lasts for 3 months. Does Digicert have a one-year or script-renewable free single domain certificate? Thank you very much for all your help.
