Class V2Form

java.lang.Object

iaik.x509.attr.V2Form

All Implemented Interfaces:

AttCertIssuer

public class V2Form
extends java.lang.Object
implements AttCertIssuer

This class implements the AC type V2Form.

The Internet Attribute Certificate Profile for Authorization specifies the V2Form type as a NOT TO BE USED option for identifying the issuer of an attribute certificate (entity who signs the attribute certificate):

 V2Form ::= SEQUENCE {
   issuerName            GeneralNames  OPTIONAL,
   baseCertificateID     [0] IssuerSerial  OPTIONAL,
   objectDigestInfo      [1] ObjectDigestInfo  OPTIONAL
           -- at least one of issuerName, baseCertificateID
           -- or objectDigestInfo MUST be present
 }
 

Attribute certifcates conforming to the Internet Attribute Certificate Profile for Authorization presented in draft-ietf-pkix-ac509prof-06.txt have to use the V1Form choice for representing the issuer:

 AttCertIssuer ::= CHOICE {
    v1Form   GeneralNames,  -- v1 or v2
    v2Form   [0] V2Form     -- v2 only
 }
