PolicyQualifierInfo (6.2 API Documentation)

java.lang.Object
- iaik.asn1.structures.PolicyQualifierInfo

public class PolicyQualifierInfo
extends java.lang.Object

This class implements the ASN.1 type PolicyQualifierInfo.

The PolicyQualifierInfo type is used for defining the information specified by the PolicyInformation terms of the X.509v3 Certificate Policies extension, indicating the policy under which the certificate has been issued and the purposes for which the certificate may be used.

 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 PKIX X.509 Certificate and CRL profile (RFC 5280) 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 {
      ia5String        IA5String      (SIZE (1..200)),
      visibleString    VisibleString  (SIZE (1..200)),
      bmpString        BMPString      (SIZE (1..200)),
      utf8String       UTF8String     (SIZE (1..200)) }

The policy qualifier IDs for the CPS Pointer and User Notice qualifiers are defined as follows:

 id-qt ::= { id-pkix 2 }  -- pkix arc for qualifier types
 

 id-qt-cps      OBJECT IDENTIFIER ::=  { id-qt 1 }
 id-qt-unotice  OBJECT IDENTIFIER ::=  { id-qt 2 }
 

 PolicyQualifierId ::= OBJECT IDENTIFIER ( id-qt-cps | id-qt-unotice )

More information can be found in the PKIX internet draft draft-ietf-pkix-ipki-part1-06.txt, section 4.2.1.5 "Certificate Policies".

When creating a PolicyQualifierInfo object to be set for a PolicyInformation, use a proper constructor for either specifying a CPS Pointer qualifier or a User Notice qualifier, 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("IAIK",
     notice_nr, null);

```
public PolicyQualifierInfo(java.lang.String CpsUri)
```
    Creates a new PolicyQualifierInfo from a CPS Pointer qualifier. The CPS Pointer qualifier contains a pointer to a Certification Practice Statement (CPS) published by the CA. The pointer is in the form of an URI.
    
    Parameters:
    
    CpsUri - the pointer as URI
  - PolicyQualifierInfo
```
public PolicyQualifierInfo(java.lang.String organization,
                           int[] noticeNumbers,
                           java.lang.String explicitText)
```
    Creates a new PolicyQualifierInfo from a user notice qualifier specified by reference information and/or an explicit text.
    A user notice qualifier has two optional fields:
```
 UserNotice ::= SEQUENCE {
   noticeRef     NoticeReference OPTIONAL,
   explicitText  DisplayText OPTIONAL}
 
```
    A notice reference consists of an organization name and a notice number identifying a particular textual statement prepared by this organization:
```
 NoticeReference ::= SEQUENCE {
   organization  DisplayText,
   noticeNumbers SEQUENCE OF INTEGER }
 
```
    An explicitText field includes the textual statement directly in the certificate. The explicitText field is a string with a maximum size of 200 characters:
```
 DisplayText ::= CHOICE {
      ia5String        IA5String      (SIZE (1..200)),
      visibleString    VisibleString  (SIZE (1..200)),
      bmpString        BMPString      (SIZE (1..200)),
      utf8String       UTF8String     (SIZE (1..200)) }
 
```
    According RFC 5280 By default organization and explicitText are encoded as UTF8String.
    Parameters:
    
    organization - the organization [or null if not needed; sets noticeNumbers also to null]
    
    noticeNumbers - notice numbers [or null if not needed; sets organization also to null]
    
    explicitText - the textual statement or null if not needed
    
    Throws:
    
    java.lang.IllegalArgumentException - if explicitText is present but too long (more than 200 characters)
  - PolicyQualifierInfo
```
public PolicyQualifierInfo(ASN1Object organization,
                           int[] noticeNumbers,
                           ASN1Object explicitText)
```
    Creates a new PolicyQualifierInfo from a user notice qualifier specified by reference information and/or an explicit text.
    A user notice qualifier has two optional fields:
```
 UserNotice ::= SEQUENCE {
   noticeRef     NoticeReference OPTIONAL,
   explicitText  DisplayText OPTIONAL}
 
```
    A notice reference consists of an organization name and a notice number identifying a particular textual statement prepared by this organization:
```
 NoticeReference ::= SEQUENCE {
   organization  DisplayText,
   noticeNumbers SEQUENCE OF INTEGER }
 
```
    An explicitText field includes the textual statement directly in the certificate. The explicitText field is a string with a maximum size of 200 characters:
