有的oracle版本没有加解密函数,以下操作可以手动添加
oracle数据使用加密解密,我们首先要先赋予dbms_crypto权限给用户。
grant execute on dbms_crypto to user;

CREATE OR REPLACE FUNCTION F_ENCRYPT_DATA(NUMBER_IN IN VARCHAR2,
SECRETKEY IN VARCHAR2) RETURN RAW IS
NUMBER_IN_RAW RAW(128) := UTL_I18N.STRING_TO_RAW(NUMBER_IN, 'AL32UTF8');
KEY_NUMBER VARCHAR2(32) := SECRETKEY;
