数据库安全至关重要，尤其是Access数据库，由于其加密算法过于简单，使得Access单靠密码无法保证其安全，本代码通过改变数据库头文件实现对Acess数据库的加密。-Database security is crucial, especially the Access database, because of its too simple encryption algorithm, making Access a password alone can not guarantee their safety, the code by changing the header file database achieve Acess database encryption.
