Class PolicyQualifierInfo
- java.lang.Object
-
- java.security.cert.PolicyQualifierInfo
public class PolicyQualifierInfo extends Object
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.

Constructor Detail
PolicyQualifierInfo
public PolicyQualifierInfo(byte[] encoded) throws IOException
Creates an instance of PolicyQualifierInfo
from the encoded bytes. The encoded byte array is copied on construction.
- Parameters:
-
encoded
- a byte array containing the qualifier in DER encoding - Throws:
-
IOException
- thrown if the byte array does not represent a valid and parsable policy qualifier
Method Detail
getPolicyQualifierId
public final String getPolicyQualifierId()
Returns the policyQualifierId
field of this PolicyQualifierInfo
. The policyQualifierId
is an Object Identifier (OID) represented by a set of nonnegative integers separated by periods.
- Returns:
- the OID (never
null
)
getEncoded
public final byte[] getEncoded()
Returns the ASN.1 DER encoded form of this PolicyQualifierInfo
.
- Returns:
- the ASN.1 DER encoded bytes (never
null
). Note that a copy is returned, so the data is cloned each time this method is called.
getPolicyQualifier
public final byte[] getPolicyQualifier()
Returns the ASN.1 DER encoded form of the qualifier
field of this PolicyQualifierInfo
.
- Returns:
- the ASN.1 DER encoded bytes of the
qualifier
field. Note that a copy is returned, so the data is cloned each time this method is called.
toString
public String toString()
Return a printable representation of this PolicyQualifierInfo
.
