Bouncy Castle PKIX APIs (FIPS Distribution) 1.0.7 · 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()));
