该例子的加密原理是由外壳工具 AXPROTECTOR和 WUPI函数功能组成，用户除了可以用

自动外壳工具保护程序外，还可以对源程序的函数段进行自定义加密，并且可以通过

WUPI函数来控制该函数段在内存中什么时候解密运行，什么时候再次加密保护起来-The principle of this example is encrypted by the shell tool AXPROTECTOR and WUPI function-composition, the user can use in addition to

Automatic shell tool saver, but also can be the source of the function segments custom encryption, and can be

WUPI function to control the function segment decrypted in memory when running, when re-encrypt protected
