Encryption based on the AES algorithm has been added to the built-in encryption providers available to secure the Servlet implementation of the WebFOCUS Client. To implement AES128, AES192, or AES256 encryption, modify the WFENCR context parameter in the Web application (for example, in the ibi\WebFOCUS77\config\webconfig.xml file or using your Application Server Administration interface). For more information, see the WebFOCUS Security and Administration manual.
