public class BasicConstraintsExtension extends Extension implements CertAttrSet
This class represents the Basic Constraints Extension.The basic constraints extension identifies whether the subject of the certificate is a CA and how deep a certification path may exist through that CA.
The ASN.1 syntax for this extension is: BasicConstraints ::= SEQUENCE { cA BOOLEAN DEFAULT FALSE, pathLenConstraint INTEGER (0..MAX) OPTIONAL }
