CMSEnvelopedDataStreamGenerator (Bouncy Castle Library 1.37 API Specification)

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.addKeyTransRecipient(cert);

      ByteArrayOutputStream  bOut = new ByteArrayOutputStream();
      
      OutputStream out = edGen.open(
                              bOut, CMSEnvelopedDataGenerator.AES128_CBC, "BC");*
      out.write(data);
      
      out.close();
