MYSQL AES 加密

使用mysql的加密函数运行：

select HEX(AES_ENCRYPT( 'test aes encrypt','123')) as aesTest

输出密文：

17CDAE577C715A0B5A922BF07462622AF15884B6D0F596B0241DC8F966C4A93F

https://dev.mysql.com/doc/refman/8.0/en/encryption-functions.html#function_aes-encrypt

官方文档解释：

The block_encryption_mode system variable controls the mode for block-based encryption algorithms. Its default value is <font color="red"> aes-128-ecb </font>, which signifies encryption using a key length of 128 bits and ECB mode. For a description of the permitted values of this variable, see Section 5.1.8, “Server System Variables” .

该网加密结果为：

17cdae577c715a0b5a922bf07462622af15884b6d0f596b0241dc8f966c4a93f

与mysql加密结果一致，只是大小写差异。

原因：mysql8 之前的版本中加密规则是mysql_native_password,而在mysql8之后,加密规则改为caching_sha2_password

解决办法：

1、升级客户端

2、把mysql用户登录密码加密规则还原成mysql_native_password：

ALTER USER xxxx IDENTIFIED WITH mysql_native_password BY '新密码'
