使用Oracle Wrap工具加密你的代码
2024-08-21 04:12:37
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 varchar2
is
ls_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
[oracle@jumper tools]$ sqlplus scott/tiger SQL*Plus: Release 9.2.0.4.0 - Production on Mon Nov 15 21:56:36 2004 Copyright (c) 1982, 2002, Oracle Corporation. All rights reserved. Connected to:

3.使用wrap加密及加密后的代码
[oracle@jumper tools]$ wrap iname=f_get_rowid.sql oname=f_get_rowid.plb PL/SQL Wrapper: Release 9.2.0.4.0- Production on Mon Nov 15 21:59:39 2004 Copyright (c) Oracle Corporation 1993, 2001. All Rights Reserved. Processing f_get_rowid.sql to f_get_rowid.plb [oracle@jumper tools]$ cat f_get_rowid.plb
create or replace function get_rowid wrapped

4.测试加密后的代码
[oracle@jumper tools]$ exit
exit SQL> drop function get_rowid; Function dropped. SQL> @f_get_rowid.plb Function created. SQL> select get_rowid('AAABiPAABAAAFRSAAA') from dual; GET_ROWID('AAABIPAABAAAFRSAAA')
-----------------------------------------------------------------
Object# is :6287
Relative_fno is :1
Block number is :21586
Row number is :0 SQL>
注意，如果出现如下错误：
kgepop: no error frame. to pop to for error 1801
则需要设置正确的环境变量：NLS_LANG
例如在WIndows下可以如下设置：
C:\oracle\ora92\bin>set NLS_LANG=CHINESE_CHINA.ZHS16GBK
