Class HMACwith3DESAuthenticatedDataDemo

java.lang.Object
  demo.cms.authenticatedData.AuthenticatedDataDemo
      demo.cms.authenticatedData.HMACwith3DESAuthenticatedDataDemo

public class HMACwith3DESAuthenticatedDataDemo
extends AuthenticatedDataDemo

Demonstrates the usage of class AuthenticatedDataStream and AuthenticatedData for recipient-specific protecting the integrity of a message using the CMS type AuthenticatedData with the HMACwith3DESwrap algorithm for wrapping the HMAC key.

Attention: This demo uses Static-Static Diffie-Hellman as key management technique for providing origin authentication. The mac key is wrapped by using the HMACwith3DESwrap algorithm as specified by RFC 3537.

This demo requires that you have iaik_esdh.jar (or iaik_jce_full.jar) in your classpath. You can download it from https://sic.tech/products/core-crypto-toolkits/jca-jce/.

Constructor Detail

HMACwith3DESAuthenticatedDataDemo

public HMACwith3DESAuthenticatedDataDemo()
                                  throws java.io.IOException,
                                         java.security.NoSuchAlgorithmException

Creates an HMACwith3DESAuthenticatedDataDemo and setups the demo certificates.
Keys and certificates are retrieved from the demo KeyStore ("cms.keystore") file which has to be located in your current working directory and may be created by running SetupCMSKeyStore.
HMACwith3DESwrap is used as key wrap algorithm.

Throws:

java.io.IOException - if an file read error occurs

java.security.NoSuchAlgorithmException - if no implementation for the requested key wrap algorithm is available

                 throws java.lang.Exception

Main method.

Throws:

java.io.IOException - if an I/O error occurs when reading required keys and certificates from files
