a OA system needs to provide a cryptographic module, the user confidential information (such as password, mailbox, etc.) after encryption, stored in the database, the system has defined the database operation class, in order to improve the development efficiency, now need to reuse existing encryption algorithms, these cryptographic algorithms are encapsulated in the class provided by the third party, some even no source code, Try the adapter mode, design the module, and reuse the third-party enc

Game engine rating !!

cool! By myself, I will not post it. Below I will post the Ogre plug-in novodex effect. The powerful scalability of ogre allows it to plug in multiple third-party physical engines, including Tokamak , Ode And the coolest Novodex . As a physical engine of commercial quality,Novodex features many patterns, fast speed, and stable operation. You can put thousands of rigid bodies in novodex without affecting the speed.
