Reference documentation and code samples for the Certificate Authority v1 API class CertificateDescription.Types.SubjectDescription.
These values describe fields in an issued X.509 certificate such as the
distinguished name, subject alternative names, serial number, and lifetime.
The time after which the certificate is expired.
Per RFC 5280, the validity period for a certificate is the period of time
from not_before_time through not_after_time, inclusive.
Corresponds to 'not_before_time' + 'lifetime' - 1 second.
