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()));

Method Detail

generate

public CMSAuthenticatedData generate(CMSTypedData typedData,
                                     MacCalculator macCalculator)
                              throws CMSException
Generate an authenticated data object from the passed in typedData and MacCalculator.

Parameters:
typedData - the data to have a MAC attached.
macCalculator - the calculator of the MAC to be attached.
Returns:
the resulting CMSAuthenticatedData object.
Throws:
CMSException - on failure in encoding data or processing recipients.

generate
