public class CMSSignedData
extends java.lang.Object

general class for handling a pkcs7-signature message. A simple example of usage - note, in the example below the validity of the certificate isn't verified, just the fact that one of the certs matches the given signer...

  CertStore               certs = s.getCertificatesAndCRLs("Collection", "BC");
  SignerInformationStore  signers = s.getSignerInfos();
  Collection              c = signers.getSigners();
  Iterator                it = c.iterator();
  
  while (it.hasNext())
  {
      SignerInformation   signer = (SignerInformation)it.next();
      Collection          certCollection = certStore.getMatches(signer.getSID());

      Iterator        certIt = certCollection.iterator();
      X509CertificateHolder cert = (X509CertificateHolder)certIt.next();
  
      if (signer.verify(new JcaSimpleSignerInfoVerifierBuilder().setProvider("BC").build(cert)))
      {
          verified++;
      }   
  }
