java.lang.Objectjava.security.cert.PolicyQualifierInfo
public class PolicyQualifierInfo
Disabled: no SafeJ information.
An immutable policy qualifier represented by the ASN.1 PolicyQualifierInfo structure.
The ASN.1 definition is as follows:
PolicyQualifierInfo ::= SEQUENCE { policyQualifierId PolicyQualifierId, qualifier ANY DEFINED BY policyQualifierId }
A certificate policies extension, if present in an X.509 version 3 certificate, contains a sequence of one or more policy information terms, each of which consists of an object identifier (OID) and optional qualifiers. In an end-entity certificate, these policy information terms indicate the policy under which the certificate has been issued and the purposes for which the certificate may be used. In a CA certificate, these policy information terms limit the set of policies for certification paths which include this certificate.
A Set
of PolicyQualifierInfo
objects are returned
by the PolicyNode.getPolicyQualifiers
method. This allows applications with specific policy requirements to
process and validate each policy qualifier. Applications that need to
process policy qualifiers should explicitly set the
policyQualifiersRejected
flag to false (by calling the
PKIXParameters.setPolicyQualifiersRejected
method) before validating
a certification path.
Note that the PKIX certification path validation algorithm specifies
that any policy qualifier in a certificate policies extension that is
marked critical must be processed and validated. Otherwise the
certification path must be rejected. If the
policyQualifiersRejected
flag is set to false, it is up to
the application to validate all policy qualifiers in this manner in order
to be PKIX compliant.
Concurrent Access
All PolicyQualifierInfo
objects must be immutable and
thread-safe. That is, multiple threads may concurrently invoke the
methods defined in this class on a single PolicyQualifierInfo
object (or more than one) with no ill effects. Requiring
PolicyQualifierInfo
objects to be immutable and thread-safe
allows them to be passed around to various pieces of code without
worrying about coordinating access.
