Demonstrates the Chilkat Mime.ContainsEncryptedParts method, which returns whether the currently visible MIME tree contains a CMS/PKCS #7 encrypted entity. It takes no arguments.

Note: The file path is relative to the application's current working directory. Absolute paths may also be used. Supply the path to your own file.

// Important: Don't forget to include the call to System.loadLibrary
