测试--MD5--加密

CREATE TABLE `test`.`testmd5` (
`id` INT ( 4 ) NOT NULL,
`name` VARCHAR ( 20 ) NOT NULL,
`pwd` VARCHAR ( 50 ) NOT NULL,
PRIMARY KEY ( `id` )
) ENGINE = INNODB DEFAULT CHARSET = utf8;

SELECT id,name,pwd FROM testmd5

-- 明文密码
INSERT into testmd5 values (1,'zhangsan','123456'),(2,'lis','123456'),(3,'wangyu','123456'),(4,'zhaoliu','123456'),(5,'songqi','123456'),(6,'daba','123456')

-- 加密密码
UPDATE testmd5 SET pwd=MD5(pwd) WHERE id=1;

--插入时候就用加密

INSERT into testmd5 values (7,'xiaoming',MD5('123456'))

--如何校验：将用户传递进来的密码，进行md5加密，然后对加密后的值进行比对
SELECT * FROM testmd5 WHERE `name`='xiaoming'AND pwd=md5('123456')
