public class PolicyMapping

extends java.lang.Object

implements ASN1Type

This class implements a policy mapping as used by the X509v3 PolicyMappings extenscion to be included into CA certificates.

A policy mapping is a pair of object identifiers specifying an issuerDomainPolicy and a subjectDomainPolicy for indicating that the issuing CA considers its issuerDomainPolicy equivalent to the subject CA's subjectDomainPolicy.

The PolicyMappings extension is defined as sequence of such policy mapping pairs:

 PolicyMappings ::= SEQUENCE SIZE (1..MAX) OF SEQUENCE {
   issuerDomainPolicy      CertPolicyId,
   subjectDomainPolicy     CertPolicyId }
 

 CertPolicyId ::= OBJECT IDENTIFIER
 

When creating a PolicyMapping object to be used for the PolicyMappings extension, specify issuerDomainPolicy and subjectDomainPolicy as ObjectID instances, e.g.:

 ObjectID iaikPolicy1 = new ObjectID("1.2.3.4.5.1", "iaikPolicy1");
 ObjectID iaikPolicy2 = new ObjectID("1.2.3.4.5.2", "iaikPolicy2");
 PolicyMapping policyMap = new PolicyMapping(iaikPolicy1, iaikPolicy2);

Constructor Detail

PolicyMapping

public PolicyMapping()

Default constructor. Creates an empty PolicyMapping object. Implements the ASN1Type interface.

PolicyMapping

public PolicyMapping(ASN1Object obj)
              throws CodingException

Creates a policy mapping from an ASN1Object.

The given policy mapping ASN1Object is parsed for issuerDomainPolicy and subjectDomainPolicy object identifiers.

Parameters:

obj - the PolicyMapping as ASN1Object

Throws:

CodingException - if the given ASN1Object is not a PolicyMapping

PolicyMapping

public PolicyMapping(ObjectID issuerDomainPolicy,
                     ObjectID subjectDomainPolicy)

Creates a policy mapping from an issuerDomainPolicy and a subjectDomainPolicy.

For instance:

 ObjectID iaikPolicy1 = new ObjectID("1.2.3.4.5.1", "iaikPolicy1");
 ObjectID iaikPolicy2 = new ObjectID("1.2.3.4.5.2", "iaikPolicy2");
 PolicyMapping policyMap = new PolicyMapping(iaikPolicy1, iaikPolicy2);
 

Parameters:

issuer_domain_policy - the issuer domain policy object identifier

subject_domain_policy - the subject domain policy object identifier

Method Detail

toASN1Object

public ASN1Object toASN1Object()

Returns this policy mapping as (SEQUENCE) ASN1Object.

Specified by:

toASN1Object in interface ASN1Type

Returns:

this policy mapping as ASN1Object

decode

public void decode(ASN1Object obj)
            throws CodingException

Decodes a PolicyMapping from the given ASN1Object.

This method implements the ASN1Type interface. The given policy mapping ASN1Object is parsed for issuerDomainPolicy and subjectDomainPolicy object identifiers.

Specified by:

decode in interface ASN1Type

Parameters:

obj - the PolicyMapping as ASN1Object

Throws:

CodingException - if the given ASN1Object is not a PolicyMapping

getIssuerDomainPolicy

public ObjectID getIssuerDomainPolicy()

Returns the issuer domain policy.

Returns:

the issuer domain policy object identifier

getSubjectDomainPolicy

public ObjectID getSubjectDomainPolicy()

Returns the subject domain policy.

Returns:

the subject domain policy object identifier

toString

public java.lang.String toString()

Returns a string that represents the contents of PolicyMapping

Overrides:

toString in class java.lang.Object

Returns:

the string representation
