You can encrypt the database to increase the security of the information stored in UltraLite. However, you should note that there is an increase in overhead of between 5-10% as a result, resulting in decreased performance. The exact effect on performance depends on the size of your cache. If your cache is too small, encryption can add significant overhead. However, if your cache is sufficiently large, you may not see any difference at all. To determine what the optimal cache size for your scenario is, you can graph the database performance with benchmark tests.
