PLS-00201:必须声明标识符“DBMS_OBFUSCATION_TOOLKIT.DESENCRYPT”

Question

下面是我的包代码：

create or replace package body encryption as
    key_string   varchar2(64) := '$0@!H&^%#8I^~!JYE&#$55JKH*(@#$^^';
    encrypted_string varchar2(2048);
    decrypted_string varchar2(2048);

function encrypt (input_string IN varchar2) return varchar2 is
   BEGIN
       encrypted_string :=null;   

       dbms_obfuscation_toolkit.DESEncrypt(input_string =>pad(input_string),
                                       key_string   => key_string,
                                       encrypted_string=> encrypted_string);
       RETURN encrypted_string;                                    
   END;
   
function decrypt(input_string In varchar2) RETURN varchar2 IS
    BEGIN
        decrypted_string :=null;
        encrypted_string :=null; 

        dbms_obfuscation_toolkit.DESDecrypt(input_string => UTL_RAW.cast_to_varchar2(input_string),
                          key_string   =>key_string,
                                          decrypted_string=>decrypted_string);
    
        RETURN RTRIM(decrypted_string,'*');                                   
    END;
END;

运行此命令后，我在Oracle21c中收到以下错误，但在Oracle18c中运行成功。

看起来特权用户(例如SYS，如果您没有任何其他特权用户)应该

grant execute on DBMS_OBFUSCATION_TOOLKIT to your_user;
