Alibaba Cloud SSL Certificates Service allows you to renew a certificate before it expires. The remaining validity period of the original certificate is added to the validity period of the renewed certificate. This prevents the website that is bound to the certificate from being identified as insecure if the certificate is not updated in time. You can renew a certificate that is due to expire in the SSL Certificates Service console. For more information, see Log on to the Alibaba Cloud SSL Certificate console.
You can purchase a new certificate on the Alibaba Cloud Certificates Service page in the SSL Certificates Service console. For more information, see On the SSL Certificates page, click Purchase Certificate.
- The remaining validity period of the original certificate is added to the validity
period of the renewed certificate.
Note If the current certificate is about to expire and you purchase a new one instead of renewing the current certificate at expiration, the validity period of the new certificate will not be added to the remaining validity period of the current certificate.
- A renewed certificate is issued faster than a purchased certificate.
- When you apply for a purchased certificate, you must enter application information,
but you do not need to do so for a renewed certificate.
Note Alibaba Cloud SSL Certificates Service stores your information about certificate application. When you apply for a certificate after it is renewed, the system automatically fills in the historical information that you entered when you previously applied for the certificate.
