org.bouncycastle.cms.CMSSignedDataParser

Direct Known Subclasses:

SMIMESignedParser

public class CMSSignedDataParser
extends CMSContentInfoParser

Parsing class for an CMS Signed Data object from an input stream.

Note: that because we are in a streaming mode only one signer can be tried and it is important that the methods on the parser are called in the appropriate order.

A simple example of usage for an encapsulated signature.

Two notes: first, in the example below the validity of the certificate isn't verified, just the fact that one of the certs matches the given signer, and, second, because we are in a streaming mode the order of the operations is important.

      CMSSignedDataParser     sp = new CMSSignedDataParser(encapSigData);

      sp.getSignedContent().drain();

      CertStore               certs = sp.getCertificatesAndCRLs("Collection", "BC");
      SignerInformationStore  signers = sp.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();

          System.out.println("verify returns: " + signer.verify(new JcaSimpleSignerInfoVerifierBuilder().setProvider("BC").build(cert)));
      }
 

Note also: this class does not introduce buffering - if you are processing large files you should create the parser with:

          CMSSignedDataParser     ep = new CMSSignedDataParser(new BufferedInputStream(encapSigData, bufSize));
  

where bufSize is a suitably large buffer size.
