+----netscape.security.x509.PolicyConstraintsExtension
- public class PolicyConstraintsExtension
- extends Extension
- implements CertAttrSet
This class defines the certificate extension which specifies the
Policy constraints.
The policy constraints extension can be used in certificates issued
to CAs. The policy constraints extension constrains path validation
in two ways. It can be used to prohibit policy mapping or require
that each certificate in a path contain an acceptable policy
identifier.
The ASN.1 syntax for this is (IMPLICIT tagging is defined in the
module definition):
PolicyConstraints ::= SEQUENCE {
requireExplicitPolicy [0] SkipCerts OPTIONAL,
inhibitPolicyMapping [1] SkipCerts OPTIONAL
}
SkipCerts ::= INTEGER (0..MAX)
