JWT: header, payload, signature

Conquer Authentication with Ktor: Part 6 – Implementing JSON Web Tokens

Welcome back to our journey with the Ktor framework. Our previous post introduced you to JSON Web Tokens (JWT) and their impact on authentication in modern web applications. You learned about the key benefits of JWT, such as statelessness, improved scalability, cross-platform compatibility, and enhanced security. Today, we take things a step further with a hands-on approach, showing you how to effectively implement JWT using Ktor. Follow along as we dive into the practical side of JWT with Ktor to secure your web application seamlessly and effectively. By the end of this post, you’ll have a deeper understanding of how JWT and Ktor work together to create a robust and maintainable security model.

JWT embraces trust

Conquer Authentication with Ktor: Part 5 – Introduction into JSON Web Tokens

Welcome back to our ongoing series on the Ktor framework and its impressive capabilities when it comes to web application security. In this article, we shift our focus from traditional form-based authentication to a modern, innovative one – JSON Web Tokens (JWT). JWT provides several key advantages that have led to its growing popularity. Firstly, its stateless nature promotes better scalability by eliminating the need to maintain user sessions. Secondly, JWT’s JSON structure guarantees cross-platform compatibility. This means your authentication mechanism works equally well for web apps as it does for mobile apps or other systems. Lastly, JWT proactively increases the security of your applications, preventing attacks like CSRF. So, join us today as we delve into the world of JWT, exploring its mechanics and benefits.

Session Management with Ktor

Conquer Authentication with Ktor: Part 4 – Session Management

Welcome to the continued exploration of form-based authentication with Ktor. Today’s post delves into session management—a feature that enables the persistence of user data across multiple HTTP requests. Session management allows users to securely access protected resources after initial authentication. Once the user logs in, the server persists user data and automatically re-authenticates users on subsequent requests. This is not only convenient from a user’s perspective but also reduces the risk of credential interception, a vulnerability inherent in basic authentication.

Basic auth with Ktor

Conquer Authentication with Ktor: Part 2 – Basic Authentication

Welcome to the latest chapter in our ongoing series about implementing authentication with Ktor. Having laid a solid foundation by covering the fundamentals of Ktor, we’re now prepared to delve into the realm of security protocols. In today’s post, we’re going to start with the simplest one – Basic Authentication. We’ll unpack how this protocol functions and guide you through its implementation using Ktor.
