Class SMimeSendDemo

java.lang.Object
  demo.smime.basic.SMimeSendDemo

public class SMimeSendDemo
extends java.lang.Object

This class demonstrates the usage of the IAIK S/MIME implementation for sending signed and/or encryped emails based on the JavaMail API.

To run this demo the following packages are required:

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

Usage:

 SMimeSend [-H host] [-S sender name] [-F (From) sender address] [-T (To) recipient address]
 

Example:

 SMimeSend -H mailhost -S \"John SMime\" -F smimetest@iaik.tugraz.at -T smimetest@iaik.tugraz.at
 

By default this demo used "mailhost" as host, "John SMime" as sender name, and "smimetest@iaik.tugraz.at" as sender and also as recipient mail address. "smimetest@iaik.tugraz.at" is also the email address contained in the demo certificates. Although you should specify other email addresses to send the test messages to yourself, be aware that the certificate email check may fail on the receiving side (SMimeShowDemo).
