Encrypt

Usage

Pre-work

  1. Start the MySQL service
  2. Create MySQL database (refer to ShardingProxy data source configuration rules)
  3. Create a role or user with creation permission for ShardingProxy
  4. Start Zookeeper service (for persistent configuration)

Start ShardingProxy

  1. Add mode and authentication configurations to server.yaml (please refer to the example of ShardingProxy)
  2. Start ShardingProxy (Related introduction)

Create a distributed database and sharding tables

  1. Connect to ShardingProxy
  2. Create a distributed database
CREATE DATABASE encrypt_db;
  1. Use newly created database
USE encrypt_db;
  1. Configure data source information
ADD RESOURCE ds_0 (
HOST=127.0.0.1,
PORT=3306,
DB=ds_0,
USER=root,
PASSWORD=root
);
  1. Create encrypt table
CREATE TABLE `t_encrypt` (
  `order_id` int NOT NULL,
  `user_plain` varchar(45) DEFAULT NULL,
  `user_cipher` varchar(45) DEFAULT NULL,
  PRIMARY KEY (`order_id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4
  1. Create encrypt rule
CREATE ENCRYPT RULE t_encrypt (
COLUMNS(
(NAME=user_id,PLAIN=user_plain,CIPHER=user_cipher,TYPE(NAME=AES,PROPERTIES('aes-key-value'='123456abc'))),
(NAME=order_id, CIPHER =order_cipher,TYPE(NAME=MD5))
));
  1. Alter encrypt rule
CREATE ENCRYPT RULE t_encrypt (
COLUMNS(
(NAME=user_id,PLAIN=user_plain,CIPHER=user_cipher,TYPE(NAME=AES,PROPERTIES('aes-key-value'='123456abc'))),
));
  1. Drop encrypt rule
DROP ENCRYPT RULE t_encrypt;
  1. Drop resource
DROP RESOURCE ds_0;
  1. Drop distributed database
DROP DATABASE encrypt_db;

Notice

  1. Currently, DROP DATABASE will only remove the logical distributed database, not the user’s actual database.
  2. DROP TABLE will delete all logical fragmented tables and actual tables in the database.
  3. CREATE DATABASE will only create a logical distributed database, so users need to create actual databases in advance.
