MD5密码加密

1.MD5密码加密

package com.utils;

import java.security.MessageDigest;

import sun.misc.BASE64Encoder;

//MD5密码加密
public class MD5Util {
    //密码加密
    public static String md5(String password) {
        try {
            //1.创建加密对象
            MessageDigest md5 = MessageDigest.getInstance("md5");
            //2.加密密码
            byte[] by = md5.digest(password.getBytes());
            //3.创建编码对象
            BASE64Encoder encoder = new BASE64Encoder();
            //4.对结果编码
            return encoder.encode(by);
        } catch (Exception e) {
            throw new RuntimeException(e);
        }
    }
}

2.测试

public class Test {
    public static void main(String[] args) {
        User user = new User();
        user.setPassword("123");
        System.out.println(user.getPassword());
        //密码加密
        user.setPassword(MD5Util.md5(user.getPassword()));
        System.out.println(user.getPassword());
    }
}
