Class CMSAuthenticatedDataStreamGenerator

java.lang.Object

org.bouncycastle.cms.CMSEnvelopedGenerator

org.bouncycastle.cms.CMSAuthenticatedGenerator

org.bouncycastle.cms.CMSAuthenticatedDataStreamGenerator

public class CMSAuthenticatedDataStreamGenerator
extends CMSAuthenticatedGenerator

General class for generating a CMS authenticated-data message stream.

A simple example of usage.

      CMSAuthenticatedDataStreamGenerator edGen = new CMSAuthenticatedDataStreamGenerator();

      edGen.addKeyTransRecipient(cert);

      ByteArrayOutputStream  bOut = new ByteArrayOutputStream();

      OutputStream out = edGen.open(
                              bOut, CMSAuthenticatedDataGenerator.AES128_CBC, "BC");*
      out.write(data);

      out.close();
