public class PolicyInformation

extends Object

This class implements the ASN.1 type PolicyInformation.

A sequence of policy information terms is used within a X.509v3 Certificate Policies extension for indicating the policy under which the certificate has been issued and the purposes for which the certificate may be used. Each of such policy information terms consists of an object identifier (OID) and optional qualifiers (see X.509 Certificate and CRL profile presented in RFC 2459):

 certificatePolicies ::= SEQUENCE SIZE (1..MAX) OF PolicyInformation
 

 PolicyInformation ::= SEQUENCE {
      policyIdentifier   CertPolicyId,
      policyQualifiers   SEQUENCE SIZE (1..MAX) OF PolicyQualifierInfo OPTIONAL }
 

 CertPolicyId ::= OBJECT IDENTIFIER
 

 PolicyQualifierInfo ::= SEQUENCE {
      policyQualifierId   PolicyQualifierId,
      qualifier           ANY DEFINED BY policyQualifierId }
 

The X.509 Certificate and CRL profile presented in RFC 2459 defines two policy qualifiers types:

 Qualifier ::= CHOICE {
    cPSuri         CPSuri,     -- CPS Pointer qualifier
    userNotice     UserNotice  -- User Notice qualifier
 }
 

The CPS Pointer qualifier indicates a (URI) pointer to a Certification Practice Statement (CPS) published by the CA:

CPSuri ::= IA5String

The User Notice qualifier may include a noticeRef field identifying an organization and a particular textual statement prepared by that organization, or/and an explicitText string field of up to 200 characters including the textual statement directly into the certificate:

 UserNotice ::= SEQUENCE {
   noticeRef     NoticeReference OPTIONAL,
   explicitText  DisplayText OPTIONAL}
 

 NoticeReference ::= SEQUENCE {
   organization  DisplayText,
   noticeNumbers SEQUENCE OF INTEGER }
 

 DisplayText ::= CHOICE {
   visibleString    VisibleString  (SIZE (1..200)),
   bmpString        BMPString      (SIZE (1..200)),
   utf8String       UTF8String     (SIZE (1..200)) }
 

More information can be found in RFC 2459, section 4.2.1.5 "Certificate Policies".

When creating a PolicyInformation object to be used for the CertificatePolicies extension, specify the policyQualifierId as ObjectID and the policy qualifiers as array of PolicyQualifierInfo objects, e.g.:

 int[] notice_nr = {12, 35};
 ObjectID iaik_policy_id = new ObjectID("1.2.3.4.5", "iaik_policy_id");
 PolicyQualifierInfo[] policy_qualifier = new PolicyQualifierInfo[1];
 policy_qualifier[0] = new PolicyQualifierInfo("IAIK", notice_nr, null);
 PolicyInformation policy_info = new PolicyInformation(iaik_policy_id, policy_qualifier);
