the class AS4DumpReader method decryptAS4In.

/**
 * Utility method to decrypt dumped .as4in message late.<br>
 * Note: this method was mainly created for internal use and does not win the
 * prize for the most sexy piece of software in the world ;-)
 *
 * @param aAS4InData
 *        The byte array with the dumped data.
 * @param aCF
 *        The Crypto factory to be used. This crypto factory must use use the
 *        private key that can be used to decrypt this particular message. May
 *        not be <code>null</code>.
 * @param aHttpHeaderConsumer
 *        An optional HTTP Header map consumer. May be <code>null</code>.
 * @param aDecryptedConsumer
 *        The consumer for the decrypted payload - whatever that is :). May
 *        not be <code>null</code>.
