oracle.security.crypto.cert.X509Extension
oracle.security.crypto.cert.ext.BasicConstraintsExtension
public class BasicConstraintsExtension
Represents the Basic Constraints certificate extension from RFC 2459. This extension MUST be critical in CA certificates, and MAY be critical in end-entity certificates.
The path length constraint only makes sense if the CA flag is true
. The default value for path length is null
, indicating no limit on the number of following certificates in a chain. A value of 0
indicates that only an end-entity certificate may follow the certificate having this extension. Non-null
values must be non-negative.
