Class CMSEncryptedDataInputConnector

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

All Implemented Interfaces:

CMSInputConnector

public class CMSEncryptedDataInputConnector

extends java.lang.Object

implements CMSInputConnector

A CMSEncryptedDataInputConnector is used in place of a CMSEncryptedDataInputStream when reading nested CMS objects containing encrypted-data structures.

A CMSEncryptedDataInputConnector is essentially a input stream filter that unwraps the CMS encrypted-data structure from the data read in. A CMSEncryptedDataInputConnector expects the Content field of the CMS ContentInfo structure i.e. the underlying input stream must be positioned just after the explicit [0] tag wrapper.

Creates a CMSEncryptedDataInputConnector.

Method Summary

oracle.security.crypto.asn1.ASN1ObjectID	getEnclosedContentType() Returns the content type of the encrypted content.
java.io.InputStream	getInputStream() Returns the underlying input stream governing this connector.
