Class CMSSignedDataOutputConnector

java.lang.Object
oracle.security.crypto.cms.CMSSignedDataOutputConnector

All Implemented Interfaces:

CMSOutputConnector

public class CMSSignedDataOutputConnector

extends java.lang.Object

implements CMSOutputConnector

A CMSSignedDataOutputConnector is used in place of a CMSSignedDataOutputStream when constructing nested CMS objects containing signed-data structures.

A CMSSignedDataOutputConnector is essentially an output stream filter that wraps the data written to it within a CMS signed-data structure. Only the Content field of the CMS ContentInfo structure minus the the explicit [0] tag wrapper is written to the underlying output stream.

See Also:

CMSOutputConnector, CMSSignedDataOutputStream

Constructor Summary

CMSSignedDataOutputConnector(CMSOutputConnector conn, java.util.Vector signers, java.util.Vector certificates, java.util.Vector crls, oracle.security.crypto.asn1.ASN1ObjectID contentType, boolean createExternalSignatures)
Creates a CMSSignedDataOutputConnector.

CMSSignedDataOutputConnector(java.io.OutputStream out, java.util.Vector signers, java.util.Vector certificates, java.util.Vector crls, oracle.security.crypto.asn1.ASN1ObjectID contentType, boolean createExternalSignatures)
Creates a CMSSignedDataOutputConnector.

Method Summary

oracle.security.crypto.asn1.ASN1ObjectID	getExposedContentType() Returns the content type of the data that is output to the underlying output stream.
java.io.OutputStream	getOutputStream() Returns the output stream governed by this connector.

                             throws java.security.NoSuchAlgorithmException

Creates a CMSSignedDataOutputConnector.

Note the change in the exceptions thrown

Exceptions no longer thrown : AlgorithmIdentifierException

Exceptions introduced : NoSuchAlgorithmException

Parameters:

out - The underlying output stream.

signers - A collection of signers i.e CMSSignerInfo Objects.

certificates - A collection of Certificates that are to be be added to the signed-data Object.

crls - A collection of CRL's that are to be be added to the signed-data Object.

contentType - The content type of the enclosed data that is being signed.

createExternalSignatures - Specify whether External Signatures are to be created i.e. signed content is not written to the output stream.

Throws:

java.security.NoSuchAlgorithmException - An error occurred during the initialization

CMSSignedDataOutputConnector

                                    java.util.Vector signers,
                                    java.util.Vector certificates,
                                    java.util.Vector crls,
                                    oracle.security.crypto.asn1.ASN1ObjectID contentType,
