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();
