Conquer Authentication with Ktor: Part 4 – Session Management

ByTomas Zezula

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.

Conquer Authentication with Ktor: Part 2 – Basic Authentication

ByTomas Zezula

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.

Conquer Authentication with Ktor: Part 1 – Getting Started

ByTomas Zezula

This post is part of a series. In today’s post, we’ll create a project from scratch, defining API endpoints to build upon. I’ll demonstrate how to use Ktor to develop a web server, which dependencies to install, and how to structure the project for easy maintenance. There’s a lot to cover, so let’s get started!

Launching a Guide to Conquer Authentication with Ktor

ByTomas Zezula

Welcome to the first post on the subject of authentication with Ktor. As developers, we appreciate the importance of security, but integrating it smoothly within our backend services can sometimes seem like a daunting task. However, when working with Kotlin and Ktor, the task becomes much more approachable due to concise syntax and flexibility. This series aims to delve into the diverse authentication mechanisms. We will find our way through Basic Auth, Form Auth, to more complex ones like JWT and OAuth. Whether you’re new to Ktor or looking to broaden your horizons, this series will offer practical, hands-on experiences to help you effectively bring security to your backend applications.

Streamlining Console Output Verification with Kotest

ByTomas Zezula

Console logging is often perceived as a bad practice, but in specific contexts, it’s quite suitable. Consider a scenario of a workshop where printing output directly to the console enhances transparency and simplifies the project setup. Using a comprehensive logger could lead to unnecessary clutter. However, there’s a downside to directly printing to the console—it makes it challenging to verify the result. Well, at least so I thought until I accidentally stumbled upon this awesome article by Thijs Kaper. Although Spring Boot provides out-of-the-box support for output verification, it’s also possible, and sometimes preferable, to implement it independently. In this blog post, I’ll demonstrate how to create a custom spec in Kotest that you can leverage in your tests. This spec automatically captures console output and provides the result for verification.
