Leveraging Mock Service Workers for NestJS e2e tests
In the previous article, we discussed how almost any modern web application has to communicate with external systems. It's also safe to assume most of that communication is made via HTTP calls. In today's post, we'll learn how to: Intercept and stub HTTP calls in NodeJS using Mock Service Workers and NestJS as the framework - No interfaces are needed this time. Create reusable API stubs for any e2e test. Simulate network errors.

How to Add JWT-Based Authentication in NestJS
Authentication is a very important aspect of software development. It is the process of verifying a user’s identity. Authentication ensures that only authorized individuals access specific resources or perform certain actions within a system. It provides accountability by enabling the tracking of user actions and holding individuals responsible for their activities. It also gives companies data on the number of people using their products.

shiro 721 反序列化漏洞复现与原理以及Padding Oracle Attack攻击加解密原理
1.1 shiro550利用条件 知道aes加密的key且目标服务器含有可利用的攻击链。 原理 在Shiro <= 1.2.4中，反序列化过程中所用到的AES加密的key是硬编码在源码中，当用户勾选RememberMe并登录成功，Shiro会将用户的cookie值序列化，AES加密，接着base64编码后存储在cookie的rememberMe字段中. 服务端收到登录请求后，会对cookie的rememberMe字段的值进行base64解码，接着进行AES解密，然后反序列化。由于AES加密是对称式加密（key既能加密数据也能解密数据），所以当攻击者知道了AES key后，就能够构造恶意的rememberMe cookie值从而触发反序列化漏洞。 影响版本：1.2.4以下 解决payload过长的方式: 使用urlclassloader加载远程字节码 将字节码放在post的body中,恶意类实现加载body中的字节码即可.
The Ultimate Guide To Custom Role Based Access Without Third Party Libraries
Here, we have four roles: Sme, Sponsor, Admin, Operations.Initially, we had only 3 roles.Operations role was added later and Operations user has permissions similar to the Admin user.In the code, we had to replace every instance of if (user.type == USER_TYPES.ADMIN) with if (user.type == USER_TYPES.ADMIN || user.type == USER_TYPES.OPERATIONS).As this is time consuming and we can also miss many instances, we have created a roles module.
One-Time Password Generation Using speakeasy, Nest.js And MongoDB
Here, we have designed and developed a flow for OTP(One time password) for user registration and also blocking a user's account after the maximum retries for incorrect otp is exceeded. We will go in steps for generation, verification and blocking a user's account.
