public class SMimeV4BrainpoolDemo
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 ECC keys with Berainpool curves and how to parse them and verify the signatures and decrypt the content, respectively.

Although Brainpool curves may not be widely used with S/MIME applications they are, e.g., recommended by the German Federal Office for Information Security (BSI) for their Technical Guideline BSI TR-03116 defining cryptographic requirements for projects of the Federal Government. Note that whereas S/MIME in general uses AEAD cipher modes like GCM with the AuthEnvelopedData content type, BSI TR-03116 specifies GCM for use with the EnvelopedData type. For that reason GCM is used with EnvelopedData in this demo (in difference to the parent SMimeV4EccDemo which uses GCM with the AuthEnvelopedData type.

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_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).

This demo requires Java 7 or later.
