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” .

与mysql加密结果一致，只是大小写差异。

1.mysqladmin -uxxx -p password "newpassword"

这个方法win下不好用

2.进入mysql后

set password for '用户名'@'hostname' identified by 'newpassword'

3.进入mysql后

grant usage on *.* to '用户名'@'hostname' identified by 'newpassword'

4.修改user表

use mysql

update user set password=password('newpassword') where user='xxxx'
