The concept here is that if your application supports EngineManager then all EngineManager plugins will work with your application. That is you can design your application using just one engine platform and then deploy your application, and the end user of your application can plugin new algorithms at later time. EngineManager also helps you with dealing with Encryption export laws that some countries such as the US and France, and more. Now you can deploy your application with minimum encryption schemes.
