Class Overview

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();

Public Constructors

public CMSAuthenticatedDataStreamGenerator ()

base constructor

public CMSAuthenticatedDataStreamGenerator (SecureRandom rand)

This constructor is deprecated.
no longer of any use, use basic constructor.

constructor allowing specific source of randomness

Parameters
rand instance of SecureRandom to use

Public Methods

public OutputStream open (OutputStream out, String encryptionOID, int keySize, String provider)

This method is deprecated.
use open(out, MacCalculator)

generate an enveloped object that contains an CMS Enveloped Data object using the given provider.

Throws
CMSException
IOException
NoSuchAlgorithmException
NoSuchProviderException

public OutputStream open (ASN1ObjectIdentifier dataType, OutputStream out, MacCalculator macCalculator, DigestCalculator digestCalculator)

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.
digestCalculator calculator for computing digest of the encapsulated data.
Throws
CMSException

public OutputStream open (OutputStream out, String encryptionOID, Provider provider)

This method is deprecated.
use open(out, MacCalculator)

Throws
CMSException
IOException
NoSuchAlgorithmException

public OutputStream open (OutputStream out, MacCalculator macCalculator)

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

public OutputStream open (OutputStream out, MacCalculator macCalculator, DigestCalculator digestCalculator)

Throws
CMSException

public OutputStream open (OutputStream out, String encryptionOID, String provider)

This method is deprecated.
use open(out, MacCalculator)

generate an authenticated object that contains an CMS Authenticated Data object using the given provider.

Throws
java.io.IOException
CMSException
IOException
NoSuchAlgorithmException
NoSuchProviderException

public OutputStream open (ASN1ObjectIdentifier dataType, OutputStream out, MacCalculator macCalculator)

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.
Throws
CMSException

public OutputStream open (OutputStream out, String encryptionOID, int keySize, Provider provider)

This method is deprecated.
use open(out, MacCalculator)

generate an enveloped object that contains an CMS Enveloped Data object using the given provider.

Throws
CMSException
IOException
NoSuchAlgorithmException

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.

public void setBufferSize (int bufferSize)

Set the underlying string size for encapsulated data

Parameters
bufferSize length of octet strings to buffer the data.
