- public class CMSAuthenticatedDataGenerator
- extends CMSAuthenticatedGenerator
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()));
