Class CamelliaEnvelopedDataDemo

java.lang.Object
  demo.cms.envelopedData.EnvelopedDataDemo
      demo.cms.envelopedData.CamelliaEnvelopedDataDemo

public class CamelliaEnvelopedDataDemo
extends EnvelopedDataDemo

Demonstrates the usage of class EnvelopedDataStream and EnvelopedData for encrypting data using the CMS type EnvelopedData with the Camellia cipher algorithm.
Camellia is used for both content encryption and content encryption key wrapping (according to RFC 3657).

This demo creates an EnvelopedData object and subsequently shows several ways that may be used for decrypting the content for some particular recipient.

Keys and certificates are retrieved from the demo KeyStore ("cms.keystore") which has to be located in your current working directory and may be created by running the SetupCMSKeyStore program.
