public class CMSEnvelopedDataStreamGenerator extends CMSEnvelopedGenerator
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();
