Class CMSSignedDataStreamGenerator

java.lang.Object
  extended by org.bouncycastle.cms.CMSSignedGenerator
      extended by org.bouncycastle.cms.CMSSignedDataStreamGenerator

public class CMSSignedDataStreamGenerator
extends CMSSignedGenerator

General class for generating a pkcs7-signature message stream.

A simple example of usage.

      CertStore                    certs...
      CMSSignedDataStreamGenerator gen = new CMSSignedDataStreamGenerator();
  
      gen.addSigner(privateKey, cert, CMSSignedDataStreamGenerator.DIGEST_SHA1, "BC");
  
      gen.addCertificatesAndCRLs(certs);
  
      OutputStream sigOut = gen.open(bOut);
  
      sigOut.write("Hello World!".getBytes());
      
      sigOut.close();
