Our journey of exploring authentication with Ktor has come to an end. Thanks to all of you who have followed along through this tutorial series. Over the past two months and across ten comprehensive posts, we’ve covered a wide array of techniques and best practices to secure Ktor applications effectively. Read more…
Ensuring security and flexibility of web services when it comes to cross-origin resource sharing is essential. This is elegantly managed through the implementation of Cross-Origin Resource Sharing (CORS), an established practice for modern web applications. A well defined CORS policy not only enhances security but also promotes a seamless interaction between different domains. Thankfully, Ktor makes this process straightforward and efficient. In this final part of our series on authentication with Ktor, we will provide clear examples to guide you. By the end of this post, you’ll see how effortless it is to integrate CORS into your Ktor projects, ensuring your services are both secure and accessible.
In our previous post, we explored the theory behind OAuth 2.0. Today, we’re going to dive into practical application by implementing OAuth authentication with Google in a Ktor application. While the traditional approach leans towards using user session cookies to store access tokens, we’re taking a different approach. We’ll be leveraging JSON Web Tokens (JWT) to encapsulate the access token. By encapsulating the access token in JWT, we transition our authentication to a stateless model, making our server more resource efficient.
In our previous post, we wrapped up the discussion on Json Web Tokens. We’ve come far in this tutorial, gradually uncovering more complex and practical use cases. Now, we’re turning our attention to a widely adopted authorization protocol – Open Authorization 2.0. While JWT primarily ensures secure communication, OAuth focuses on the delegation of access. Today, we’ll have a closer look at key concepts of this authorization protocol.
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.
Welcome to the latest instalment in our series on implementing authentication with Ktor. In the previous post, we delved into the intricacies of basic authentication. Today, we’re enhancing our security measures by addressing one notable drawback — the need to pass user credentials with each request. By the end of this post, you’ll understand the workings of form-based authentication and why it’s a superior choice over basic authentication.
