As the requirement of practical application, we implement dynamic secret key management using multi-layer private key management strategyAs a convenience for database administration, we also provide a program for encrypt tool management.

• 密钥管理是实现数据库加密的关键技术之一。 针对实际应用情况，采用了多级密钥管理方案，在加强安全的同时，实现了密钥的动态管理。
