Class CMSEnvelopedDataOutputConnector

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

All Implemented Interfaces:

CMSOutputConnector

public class CMSEnvelopedDataOutputConnector

extends java.lang.Object

implements CMSOutputConnector

A CMSEnvelopedDataOutputConnector is used in place of a CMSEnvelopedDataOutputStream when constructing nested CMS objects containing enveloped-data structures.

A CMSEnvelopedDataOutputConnector is essentially an output stream filter that wraps the data written to it within a CMS enveloped-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, CMSEnvelopedDataOutputStream
