Class CMSEnvelopedDataStreamGenerator

  • public class CMSEnvelopedDataStreamGenerator
extends CMSEnvelopedGenerator
    General class for generating a CMS enveloped-data message stream.

    A simple example of usage. 

          CMSEnvelopedDataStreamGenerator edGen = new CMSEnvelopedDataStreamGenerator();

      edGen.addRecipientInfoGenerator(new JceKeyTransRecipientInfoGenerator(recipientCert).setProvider("BC"));

      ByteArrayOutputStream  bOut = new ByteArrayOutputStream();
      
      OutputStream out = edGen.open(
                              bOut, new JceCMSContentEncryptorBuilder(CMSAlgorithm.DES_EDE3_CBC)
                                              .setProvider("BC").build());
      out.write(data);
      
      out.close();
