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.
