  • 使用Oracle Wrap工具加密你的代码

    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> !
    [oracle@jumper tools]$ ls
    ct.sql  ddlt.sql  f_get_rowid.sql  getevent.sql       

    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

    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:oracleora92in>set NLS_LANG=CHINESE_CHINA.ZHS16GBK
