Question

我在包中有以下功能，我试图解密加密密码，但收到以下错误信息：

ORA-28817: PL/SQL function returned an error.
ORA-06512: at "SYS.DBMS_CRYPTO_FFI", 
ORA-06512: at "SYS.DBMS_CRYPTO", 
ORA-06512: at "RATOR_MONITORING_CONFIGURATION.ENCRYPT_DECRYPT_PASSWORD", line 11    
28817. 00000 -  "PL/SQL function returned an error."
*Cause:    A PL/SQL function returned an error unexpectedly.
*Action:   This is an internal error. Enable tracing to find more
           information. Contact Oracle customer support if needed.
*Document: NO

当我在不同的服务器和机器上运行此程序包时，我能够执行程序包并能够使用相同的查询解密密码。

以下是我的包裹：

create or replace PACKAGE BODY "ENCRYPT_DECRYPT_PASSWORD"
AS

  l_key RAW(128) := utl_raw.cast_to_raw('abcdefgh');

 FUNCTION decrypt_val( p_val IN varchar2 ) RETURN VARCHAR2
  IS
    l_decrypted RAW(2048);
    l_val RAW(2048) := utl_raw.cast_to_raw(p_val);
   BEGIN
         l_decrypted := dbms_crypto.decrypt
                ( src =>  l_val,
                  typ => dbms_crypto.des_cbc_pkcs5,
                  key => l_key );

         return utl_raw.cast_to_varchar2(l_decrypted);

  END decrypt_val;


FUNCTION get_decrypted_password( table_name IN varchar2,column_name IN varchar2,table_id IN varchar2,table_id_val IN varchar2 ) RETURN VARCHAR2
  IS
     encrypted_pas varchar2(100);
     decrypted_pas varchar2(100);

   BEGIN
      EXECUTE IMMEDIATE 'select ' || column_name || ' from ' || table_name || ' where ' || table_id || ' = ' || table_id_val
         INTO encrypted_pas;
         Select decrypt_val(encrypted_pas) into decrypted_pas from dual;
          return decrypt_val(encrypted_pas);
  END get_decrypted_password;

END encrypt_decrypt_password;

我也尝试向用户提供DBMS_CRYPTO权限，我的包也已经编译但是当我尝试运行以下命令来解密密码时，我收到了错误。

Select ENCRYPT_DECRYPT_PASSWORD.get_decrypted_password('DB_CONNECTION','PASSWORD','DB_CONNECTION_ID',11) from dual;

解密加密密码时出现SYS.DBMS_CRYPTO错误
