Class Overview

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

      CMSAuthenticatedDataGenerator  fact = new CMSAuthenticatedDataGenerator();

      adGen.addRecipientInfoGenerator(new JceKeyTransRecipientInfoGenerator(recipientCert).setProvider("BC"));

      CMSAuthenticatedData         data = fact.generate(new CMSProcessableByteArray(data),
                              new JceCMSMacCalculatorBuilder(CMSAlgorithm.DES_EDE3_CBC).setProvider(BC).build()));
