Class CMSEnvelopedDataInputConnector

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

All Implemented Interfaces:

CMSInputConnector

public class CMSEnvelopedDataInputConnector

extends java.lang.Object

implements CMSInputConnector

A CMSEnvelopedDataInputConnector is used in place of a CMSEnvelopedDataInputStream when reading nested CMS objects containing enveloped-data structures.

A CMSEnvelopedDataInputConnector is essentially a input stream filter that unwraps the CMS enveloped-data structure from the data read in. A CMSEnvelopedDataInputConnector 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.

CMSInputConnector, CMSEnvelopedDataInputStream

CMSEnvelopedDataInputConnector(java.io.InputStream in, java.security.PrivateKey recipientPrivateKey, java.security.cert.X509Certificate recipientCert)
Creates a CMSEnvelopedDataInputConnector.

Method Summary

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