Class CMSDigestedDataOutputConnector

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

All Implemented Interfaces:

CMSOutputConnector

public class CMSDigestedDataOutputConnector

extends java.lang.Object

implements CMSOutputConnector

A CMSDigestedDataOutputConnector is used in place of a CMSDigestedDataOutputStream when constructing nested CMS objects containing digested-data structures.

A CMSDigestedDataOutputConnector is essentially an output stream filter that wraps the data written to it within a CMS digested-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.

CMSOutputConnector, CMSDigestedDataOutputStream

Constructor Summary

CMSDigestedDataOutputConnector(CMSOutputConnector conn, AlgorithmIdentifier digestAlgID, ASN1ObjectID contentType, boolean writeEContentInfo)
Creates a CMSDigestedDataOutputConnector.

CMSDigestedDataOutputConnector(java.io.OutputStream out, AlgorithmIdentifier digestAlgID, ASN1ObjectID contentType, boolean writeEContentInfo)
Creates a CMSDigestedDataOutputConnector.

Method Summary

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 that is governed by this connector.

                               throws AlgorithmIdentifierException

Creates a CMSDigestedDataOutputConnector.

Parameters:

out - The underlying output stream.

digestAlgID - The digest algorithm identifier.

contentType - The content type of the enclosing content.

writeEContentInfo - true if the enclosed content must be written to the output stream; false otherwise.

Throws:

AlgorithmIdentifierException - Digest algorithm is not supported.

                               throws AlgorithmIdentifierException

Creates a CMSDigestedDataOutputConnector.

Parameters:

conn - The underlying output connector.

digestAlgID - The digest algorithm identifier.

contentType - The content type of the enclosing content.

writeEContentInfo - true if the enclosed content must be written to the output stream; false otherwise.
