补充说明

  • CIPHER 指定密文数据列,ASSISTED_QUERY 指定辅助查询列,LIKE_QUERY 指定模糊查询列;
  • encryptAlgorithmType 指定加密算法类型,请参考 加密算法
  • 重复的 ruleName 将无法被创建。

示例

  • 修改加密规则
  1. ALTER ENCRYPT RULE t_encrypt (
  2. COLUMNS(
  3. (NAME=user_id,CIPHER=user_cipher,ENCRYPT_ALGORITHM(TYPE(NAME='AES',PROPERTIES('aes-key-value'='123456abc')))),
  4. (NAME=order_id,CIPHER=order_cipher,ENCRYPT_ALGORITHM(TYPE(NAME='AES',PROPERTIES('aes-key-value'='123456abc'))))
  5. ));
