public class CMSEnvelopedDataGenerator
extends CMSEnvelopedGenerator

General class for generating a CMS enveloped-data message. A simple example of usage.

       CMSTypedData msg     = new CMSProcessableByteArray("Hello World!".getBytes());

       CMSEnvelopedDataGenerator edGen = new CMSEnvelopedDataGenerator();

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

       CMSEnvelopedData ed = edGen.generate(
                                       msg,
                                       new JceCMSContentEncryptorBuilder(CMSAlgorithm.DES_EDE3_CBC)
                                              .setProvider("SC").build());
