public class SMIMESigned extends org.bouncycastle.cms.CMSSignedData
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.getCertificates("Collection", "BC");
  SignerInformationStore  signers = s.getSignerInfos();
  Collection              c = signers.getSigners();
  Iterator                it = c.iterator();
  
  while (it.hasNext())
  {
      SignerInformation   signer = (SignerInformation)it.next();
      Collection          certCollection = certs.getCertificates(signer.getSID());
  
      Iterator        certIt = certCollection.iterator();
      X509Certificate cert = (X509Certificate)certIt.next();
  
      if (signer.verify(cert.getPublicKey()))
      {
          verified++;
      }   
  }

Note: if you are using this class with AS2 or some other protocol that does not use 7bit as the default content transfer encoding you will need to use the constructor that allows you to specify the default content transfer encoding, such as "binary".
