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.

      CMSEnvelopedDataGenerator  fact = new CMSEnvelopedDataGenerator();

      fact.addKeyTransRecipient(cert);

      CMSEnvelopedData         data = fact.generate(content, algorithm, "BC");
