Validity Period
The certificate validity period of a private certificate depends on the service duration of the intermediate CA:
If the service duration is less than one year, the certificate validity period cannot exceed the purchased PCA service duration. For example, if you purchased a one-month PCA service, the maximum certificate validity period is 31 days. To extend the validity period, renew the PCA service first. For more information, see Renew a CA.
If the service duration is one year or longer, you can set a validity period of 1 to 100 years.
SAN
Add SAN (Subject Alternative Name) extension attributes to a certificate to support multiple subjects.
If the certificate must support multiple subjects, add subject information by using the SAN extension.
For a server certificate, you can specify a domain name or an IP address. For a client certificate, you can specify an email address or a URI.
You can add up to 10 SAN extension attributes.
NoteSAN (Subject Alternative Name) is an extension defined in the X.509 standard that allows an SSL certificate to be bound to multiple domain names.
A URI (Uniform Resource Identifier) identifies the Alibaba Cloud resource to which the certificate belongs, such as an Elastic Compute Service (ECS) instance where the private certificate is deployed.
