使用Oracle Wrap工具加密你的代码-- 小新技术网 Xker.Com

Oracle提供Wrap工具，可以用于加密你的Package等.
不过需要注意的是，加密后的代码无法解密，你需要保管好你的源代码。

以下是个例子:

1.源代码

create or replace function get_rowid(l_rowid in varchar2)return varchar2isls_my_rowid     varchar2(200);          rowid_type      number;          object_number   number;          relative_fno    number;          block_number    number;          row_number      number;  begin dbms_rowid.rowid_info(l_rowid,rowid_type,object_number,relative_fno, block_number, row_number);           ls_my_rowid := 'Object# is      :'||to_char(object_number)||chr(10)||                'Relative_fno is :'||to_char(relative_fno)||chr(10)||                'Block number is :'||to_char(block_number)||chr(10)||                'Row number is   :'||to_char(row_number); return ls_my_rowid ;end;          /

2.代码功能测试

3.使用wrap加密及加密后的代码
