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());
