Redis is an open-source, in-memory, data structure store with optional disk writes for persistence. It can be used as a key-value database, or as a cache and message broker. Redis features built-in transactions, replication, and support for a variety of data structures such as strings, hashes, lists, sets, and others. Redis can be made highly available with Redis Sentinel and supports automatic partitioning with Redis Cluster.
3.AuthenticatingSecurityManager类中authenticate方法
Some contents of a web application are restricted, and only authorized users are allowed to view them, after they supplied the correct user name and password. The servlet technology supports applying security constraint to those contents via the configuration of the deployment descriptor (web.xml file). Now, in this chapter, we will look at how a web container supports the security constraint feature.
下载Springsecurity源码之后,看到的是多个module的,即多个module组成Springsecurity。
Purpose To enable one or more authentication services. If authentication has been installed, then it is recommended that this parameter be set to either none or to one of the authentication methods.
User对象是认证系统的核心。它们通常表示与你的站点进行交互的用户,并用于启用限制访问、注册用户信息和关联内容给创建者等。在Django的认证框架中只存在一种类型的用户,因此诸如’superusers’或管理员’staff’用户只是具有特殊属性集的user对象,而不是不同类型的user对象。
场景及需求: 项目接入了SpringBoot开发,现在需求是服务端接口返回的字段如果为空,那么自动转为空字符串。 例如: [ { "id": 1, "name": null }, { "id": 2, "name": "xiaohong" } ] 如上,格式化后的返回内容应该为: [ { "id": 1, "name": "" },
UsernamePasswordAuthenticationFilter: 用来根据传递进来的用户名及密码进行用户认证。
在之前了解了为什么所有的请求都会进行认证操作,我们也直接把目光放到源码中这个地方defaultSecurityFilterChain()

锁屏要使用指纹解锁,首先要注册指纹服务,我看过的一些大厂项目中,实际上是在KeyguardUpdate.java类中发起注册的,一般是根据当前状态,是不是已经处于上锁状态(侧边指纹机器,是不等上锁即进行指纹服务注册,屏下指纹需要等上锁后,才发起指纹服务注册)。

遂寻找了出错的原因 原因 MySQL 8 has supports pluggable authentication methods. By default, one of them named caching_sha2_password is used rather than our good old mysql_native_password (source). It should be obvious that using a crypto algorithm with several handshakes is more secure than plain password passing that has been there for 24 years! Now, the problem is mysqljs in Node (the package you install with npm i mysql and use it in your Node code) doesn't support this new default authentication method of MySQL 8, yet. The issue is in here: https://github.com/mysqljs/mysql/issues/1507 and is still open, after 3 years, as of July 2019. 在网上有看到这样一段描述,翻译过来,大概意思就是 MySQL 8 之前的版本中加密规则是mysql_native_password,而在mysql8之后,加密规则是caching_sha2_password,但是在Node中的mysqljs还不支持mysql8默认的新规则。 所以将账户的加密规则改为旧的即可 查看用户信息 select host,user,plugin,authentication_string from mysql.user;
While use of an active challenge/response paradigm to confirm liveness of the subject in a biometric authentication system can greatly strengthen security, it also carries with it an added burden on the user. Requesting the user to perform specific extra actions can increase the time to authenticate, increases the likelihood of user error, and can lead to missed detections.
对于登录功能来说,为了防止暴力破解密码,一般会对登录失败次数进行限定,在一定时间窗口超过一定次数,则锁定账户,来确保系统安全。本文主要讲述一下spring security的账户锁定。
上一篇文章 浅析 Spring Security 核心组件 中介绍了Spring Security的基本组件,有了前面的基础,这篇文章就来详细分析下Spring Security的认证过程。
假设那你已经了解RESTful API的相关概念,如果不清楚,可以阅读我之前写的这篇博客Designing a RESTful Web API.

hostapd is an IEEE 802.11 AP and IEEE 802.1X/WPA/WPA2/EAP/RADIUS Authenticator. This page is dedicated to the Linux documentation of it’s implementation and use. Please refer to the hostapd home page for information for other Operating Systems. As far a Linux is concerned, out of the old drivers you can only use these 3 drivers with hostapd: HostAP madwifi prism54 All new mac80211 based drivers that implement AP functionality are supported with hostapd’s nl80211 driver. The mac80211 subsystem moves all aspects of master mode into user space. It depends on hostapd to handle authenticating clients, setting encryption keys, establishing key rotation policy, and other aspects of the wireless infrastructure. Due to this, the old method of issuing ‘ iwconfig <wireless interface> mode master’ no longer works. Userspace programs like hostapd now use netlink (the nl80211 driver) to create a master mode interface for your traffic and a monitor mode interface for receiving and transmitting management frames. Getting hostapd Using your distributions hostapd It is advisable to try your distributions version of hostapd before taking the time to compile and install your own copy. This will make future maintenance easier as you’ll be able to use the init scripts shipped by the distro and hostapd will be updated by it as well. If your distribution ships 0.6.8 or later, you can test with this bare minimum config by creating the file hostapd-minimal.conf: #change wlan0 to your wireless device interface=wlan0 driver=nl80211 ssid=test channel=1 If that config errors out with something like: hostapd $ sudo hostapd ./hostapd-minimal.conf Configuration file: ./hostapd-minimal.conf Line 2: invalid/unknown driver ‘nl80211’ 1 errors found in configuration file ‘./hostapd-minimal.conf’ that means that your distro is not shipping hostapd with nl80211 driver support and you’ll need to follow the building instructions that follow. If it works, you can skip down to the configuring hostapd secti

Over the last few years, Google has introduced several new classes to Android for scheduling work that needs to run outside the scope of an application’s lifecycle. Many of these new schedulers implement features that improve battery life, as do updates to older methods. And as of Android Marshmallow, these schedulers became even more efficient thanks to Doze Mode, which doesn’t even require any effort from developers!

在本教程中,我们将开发一个Spring Boot应用程序,该应用程序使用JWT身份验证来保护公开的REST API。在此示例中,我们将使用硬编码的用户和密码进行用户身份验证。

如果我们不用使用drf那套认证规则,我们想自定义认证类,那么我们首先要知道,drf本身是如何定义认证规则的,也就是要查看它的源码是如何写的
#####认证组件##### 一、认证是什么就不说了,某些网页必须是用户登陆之后,才能访问的,所以这时候就需要用上认证组件。 你不用rest_framework的认证组件也行,这种认证的话,完全可以自己写出来。 二、之前再写APIView的时候,那里提到过。 不记得在哪里的话,先找dispatch方法(APIView的记得),然后是self.initial(request, *args, **kwargs), 最后找到self.perform_authentication(re
至此已经实现了基础鉴权,但是由于这里使用了restful api,获取资源的操作与修改、删除操作使用的是相同的路径,而koa-unless只支持单一的url匹配或者method匹配,两者无法混用,于是需要改写koa-unless:
dispatch根据请求方式的不同触发get/post/put/delete等方法
