Class CMSAuthenticatedDataGenerator

    java.lang.Object
      org.bouncycastle.cms.CMSEnvelopedGenerator
          org.bouncycastle.cms.CMSAuthenticatedGenerator
              org.bouncycastle.cms.CMSAuthenticatedDataGenerator

    public class CMSAuthenticatedDataGenerator

extends CMSAuthenticatedGenerator

General class for generating a CMS authenticated-data message. A simple example of usage.

          CMSAuthenticatedDataGenerator  fact = new CMSAuthenticatedDataGenerator();

          fact.addKeyTransRecipient(cert);

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