org.bouncycastle.cms.CMSAuthenticatedDataGenerator
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()));
