public class CMSAuthenticatedDataStreamGenerator
extends CMSAuthenticatedGenerator

General class for generating a CMS authenticated-data message stream.

A simple example of usage. CMSAuthenticatedDataStreamGenerator edGen = new CMSAuthenticatedDataStreamGenerator(); edGen.addRecipientInfoGenerator(new JceKeyTransRecipientInfoGenerator(cert).setProvider("BC")); ByteArrayOutputStream bOut = new ByteArrayOutputStream(); OutputStream out = edGen.open( bOut, new JceCMSMacCalculatorBuilder(CMSAlgorithm.DES_EDE3_CBC).setProvider("BC").build());* out.write(data); out.close();

base constructor
Method Detail

setBufferSize

public void setBufferSize(int bufferSize)
Set the underlying string size for encapsulated data
Parameters:
bufferSize - length of octet strings to buffer the data.

setBEREncodeRecipients

public void setBEREncodeRecipients(boolean useBerEncodingForRecipients)
Use a BER Set to store the recipient information. By default recipients are stored in a DER encoding.
Parameters:
useBerEncodingForRecipients - true if a BER set should be used, false if DER.

open

public java.io.OutputStream open(java.io.OutputStream out,
                                 MacCalculator macCalculator)
                          throws CMSException
generate an authenticated data structure with the encapsulated bytes marked as DATA.
Parameters:
out - the stream to store the authenticated structure in.
macCalculator - calculator for the MAC to be attached to the data.

                          throws CMSException
generate an authenticated data structure with the encapsulated bytes marked as type dataType.
Parameters:
dataType - the type of the data been written to the object.
out - the stream to store the authenticated structure in.
macCalculator - calculator for the MAC to be attached to the data.
