准备好一个非管理员个账号,如我用的账号为SHAREDB
要登录oracle服务器用dba账号给SHAREDB进行授权

1、添加java代码

类 DipSm4DbUtils 和 dipsm4dbutils 的名称可以自定义,两个名字对得上就行。如果自定义,后面几步用到的地方都要用自定义的名称。

此处需要使用dbeavber登录sharedb,将这一段代码作为SQL语句执行。

create or replace and compile java source named dipsm4dbutils as
import sun.misc.BASE64Decoder;
import sun.misc.BASE64Encoder;
import javax.xml.bind.DatatypeConverter;
import java.io.ByteArrayInputStream;
import java.io.ByteArrayOutputStream;
import java.io.UnsupportedEncodingException;
import java.math.BigInteger;
import java.nio.charset.StandardCharsets;
import java.util.Arrays;
import java.util.Base64;
import java.util.regex.Matcher;
import java.util.regex.Pattern;

    }

2、创建包

还是和步骤1一样,在dbeaver中用sharedb账号当做SQL语句执行

create or replace package pkg_SM4 as
  function fun_sm4_decode(f_value varchar2, f_key varchar2) return varchar2;
  function fun_sm4_encode(f_value varchar2, f_key varchar2) return varchar2;
end pkg_SM4;

3、创建函数

还是和步骤1一样,在dbeaver中用sharedb账号当做SQL语句执行

create or replace package body pkg_SM4 as
  function fun_sm4_decode(f_value varchar2, f_key varchar2)
    return varchar2 as
    language java name 'DipSm4DbUtils.strDecode(java.lang.String,java.lang.String) return java.lang.String';
   function fun_sm4_encode(f_value varchar2, f_key varchar2)
    return varchar2 as
    language java name 'DipSm4DbUtils.strEncode(java.lang.String,java.lang.String) return java.lang.String';
end pkg_SM4;

4、授权

进入oracle服务器中

# 登录
sqlplus /nolog
conn / as  sysdba
# 切换模式 这一步根据具体情况执行,12c可能需要,我的数据库服务名叫ORCL,若数据库没有PDB则不需要切换
alter session set container=ORCL; -- 不需要 c##
# 授权
exec dbms_java.grant_permission('SHAREDB','SYS:java.io.FilePermission','<<ALL FILES>>','execute');
exec dbms_java.grant_permission('SHAREDB','java.lang.RuntimePermission','*','write,read');
grant execute on SHAREDB.pkg_sm4 to SHAREDB;

5、测试

秘钥需要16位,不能多不能少

select sharedb.pkg_sm4.fun_sm4_decode('29c8ea9bfff185956d1d0d1243f7d98c','1234567812345678') from dual;

select sharedb.pkg_sm4.fun_sm4_encode('你好abc123,./','1234567812345678') from dual;

6、其他

  • sm4加密后可以选择输出hex16进制字符串、Base64字符串两种,代码中默认为hex16进制
  • hex16进制、base64的加密、解密方法java代码中都有,按需在java代码中修改即可。
