  demo.smime.ecc.SMimeV4EccDemo
      demo.smime.ecc.SimpleSMimeV4EcDemo

Direct Known Subclasses:

SimpleSMimeV4EdDemo

public class SimpleSMimeV4EcDemo
extends SMimeV4EccDemo

This class demonstrates the usage of the IAIK S/MIME implementation. It shows how to create signed and/or (authenticated) encrypted S/MIMEv4 messages using EC keys and how to parse them and verify the signatures and decrypt the content, respectively.

This demo uses one set of cryptographic algorithms. A demo that uses several combinations of algorithms is shown in SMimeV4EccDemo.

Additionally to iaik_cms.jar you also must have iaik_jce_(full).jar (IAIK-JCE, https://sic.tech/products/core-crypto-toolkits/jca-jce/), and iaik_eccelarate.jar (IAIK-ECCelerate^TM, https://sic.tech/products/core-crypto-toolkits/eccelerate/) in your classpath.

To run this demo the following packages are required:

• iaik_cms.jar (IAIK-CMS/SMIME)
• iaik_jce(_full).jar (IAIK-JCE Core Crypto Library).
• iaik_eccelerate.jar (IAIK ECC Library).
• mail.jar (JavaMail API).
• activation.jar (Java Activation Framework; required for JDK versions < 1.6).
