This series provides a concise guide on using JWT (JSON Web Tokens) to create tokens for authentication in an ASP.NET Core Web API. 1. Create a ASP.NET Core Web API Project We'll be using Visual Studio 2019 with .NET Core 3.1. 2. Add JWT Services 2.1 Install the NuGet Package Install System.IdentityModel.Tokens.Jwt via NuGet Package Manager. 2. ...

Login Handling with Sestion and JWT Session-based authentication is required to restrict page access to logged-in users only. The Gin framework provides session middleware via github.com/gin-contrib/sessions. import "github.com/gin-contrib/sessions" rootRouter.GET("/login", func(c *gin.Context) { session := sessions.Def ...

Understanding JWT Structure JWT (JSON Web Token) is an open standard (RFC 7519) that defines a compact method for securely transmitting information betwean parties as a JSON object. This information can be verified and trusted because it is digitally signed. JWTs are commonly used for authentication and authorization purposes in web application ...

Login Module After completing all the previous modules, we continue with login validation, global exception handling, transaction management, and AOP. A simple login checks the database for the employee. This can be implemented using a three-layer architecture. Controller Layer Create a LoginController class dedicated to handling login requests ...

Why Discovery Security Matters When every microservice is reachable over the network, the service registry becomes the first line of defense. An unprotected Eureka instance can be used to: Inject rogue endpoints into the load-balancer Exfiltrate configuration metadata Trigger cascading failures via forged health checks This guide shows how to ...

This system provides a unified platform for managing laboratory assets, booking schedules, equipment maintenance logs, and user permissions across academic institutions. Built with a modern full-stack architecture, it supports web and mobile access through responsive Vue-based dashboards and cross-platform uniapp clients. Architecture Overview ...

Architecture Overview To enhance session security and manage user persistence, the architecture employs a pair of JSON Web Tokens (JWT). An access_token handles immediate API requests with a short lifespan (e.g., 30 minutes), while a refresh_token maintains longer-term validity (e.g., 60 minutes) to extend sessions without re-authentication. Wh ...

JSON Web Tokens (JWT) are a compact, URL-safe means of representing claims to be transferred between two parties. By employing digital signatures, JWTs ensure that data remains tamper-proof during transit. Structure of a JWT A JWT is composed of three distinct segments separated by periods: Header: Specifies the algorithm and token type. Paylo ...

RSA Asymmetric Encryption Implementation The following example demonstrates a complete RSA encryption utility for generating key pairs, encrypting data with public keys, and decryptign with private keys. This implementation uses Java's built-in cryptographic providers with Base64 encoding for key and data portability. import javax.crypto.Cipher ...

1. Introduction Preface Welcome back to the development of the B-side project. This week we will focus on coding the right-side settings part of the editor, completing component property settings, layer settings, and page settings. To avoid getting lost in business complexities, we'll cover several typical features and knowledge points. What ...
