Class CMSEnvelopedDataGenerator

java.lang.Object
  org.bouncycastle.cms.CMSEnvelopedGenerator
      org.bouncycastle.cms.CMSEnvelopedDataGenerator

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("BC"));

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