今天在做 wrap 的测试实验的时候，出现一个很奇怪的现象，就是加密不成功。
具体表现为：1.加密后的文件大小为0kb。
2.加密后的文件仍然可视。
具体测试步骤如下：

只是装了11g的客户端的机器上测试不成功，生成的文件只有0字节；安装整个数据库的机器上测试成功，没找到确切的原因。
继续测试：

印证了Oracle官方文档的说法
Wrapping PL/SQL Code with wrap Utility
The wrap utility processes an input SQL file and wraps only the PL/SQL units in the file,
such as a package specification, package body, function, procedure, type specification, or type body.
It does not wrap PL/SQL content in anonymous blocks or triggers or non-PL/SQL code.
我想是通过在文件中查找开始位置的CREATE OR REPLACE PROCEDURE(function,package body,type)来判断加密开始和结束的位置
