Class RevocationInfoChoices

java.lang.Object
  extended by iaik.cms.RevocationInfoChoices

public class RevocationInfoChoices
extends java.lang.Object

This class implements the CMS type RevocationInfoChoices. The Cryptographic Message Syntax (CMS) ( RFC 5652) specifies the RevocationInfoChoices type for modeling certificate revocation status information:

 RevocationInfoChoices ::= SET OF RevocationInfoChoice

 RevocationInfoChoice ::= CHOICE {
   crl CertificateList,
   other [1] IMPLICIT OtherRevocationInfoFormat }

 OtherRevocationInfoFormat ::= SEQUENCE {
   otherRevInfoFormat OBJECT IDENTIFIER,
   otherRevInfo ANY DEFINED BY otherRevInfoFormat }
 
For creating an empty RevocationInfoChoices use the default constructor and subsequently supply RevocationInfos by calling method setRevocationInfos or a addRevocationInfo method.

Attention! Only X.509 certificate revocation lists (instances of iaik.x509.X509CRL) or other RevocationInfos (instances of iaik.cms.OtherRevocationInfo) can be added to a RevocationInfoChoices, e.g.:

 RevocationInfoChoices revocationInfoChoices = new RevocationInfoChoices();
 X509CRL x509Crl = ...;
 revocationInfoChoices.addRevocationInfo(x509Crl);
 OtherRevocationInfo otherRevInfo = ...;
 revocationInfoChoices.addRevocationInfo(otherRevInfo);
 
RevocationInfoChoices maybe used to provide/get revocation status information for the certificates included in a CMS SignedData or CMS OriginatorInfo object; the latter providing certificate/revocation status information of the originator of a CMS EnvelopedData or AuthenticatedData message, e.g.:
 SignedData signedData = ...;
 signedData.setRevocationInfoChoices(revocationInfoChoices);
 
 EnvelopedData envelopedData = ...;
 OriginatorInfo originatorInfo = new OriginatorInfo();
 ...
 originatorInfo.setRevocationInfoChoices(revocationInfoChoices);
 ...
 envelopedData.setOriginatorInfo(originatorInfo);
 
For parsing use the equivalent getRevocationInfoChoices() methods, e.g.:
 RevocationInfoChoices revocationInfoChoices = signedData.getRevocationInfoChoices();
