JSON Web Tokens (JWT) in .NET 6 Web API 🔒 - User Registration / Login / Authentication In this tutorial, we will discuss about the implementation of JWT authentication in asp.net core 6.0 with example. A JSON web token(JWT) is JSON Object which is used to securely transfer information over the web(between two parties). It can be used for an authentication system and can also be used for information exchange. The token is mainly composed of header, payload, signature. These three parts are separated by dots(.) Header A header in a JWT is mostly used to describe the cryptographic operations applied to the JWT like signing/decryption technique used on it. It can also contain the data about the media/content type of the information we are sending. { "typ":"JWT", "alg":"HS256" } Payload The payload is the part of the JWT where all the user data is actually added. This data is also referred to as the ‘claims’ of the JWT. This information is readable by anyone so it is always advised to not put any confidential information in here. { "userId":"b07f85be-45da", "iss": "https://provider.domain.com/", "sub": "auth/some-hash-here", "exp": 153452683 } Signature This is the third part of JWT and used to verify the authenticity of token. BASE64URL encoded header and payload are joined together with dot(.) and it is then hashed using the hashing algorithm defined in a header with a secret key. T JWT Example : header: { "alg" : "HS256", "typ" : "JWT" } Payload: { "id" : 123456789, "name" : "Manoj" } Secret: manojdeshwal JSON Web Token eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpZCI6MTIzNDU2Nzg5LCJuYW1lIjoiSm9zZXBoIn0.OpOSSw7e485LOP5PrzScxHb7SR6sAOMRckfFwi4rp7o Tools Used: Visual Studio 2022, Swagger and Postman ☕ Buy me a Coffee (Channel Support through Donation) https://www.buymeacoffee.com/manojdeshwal 📻 Recommended Courses ➤ React Ecommerce Tutorial :    • React Ecommerce   ➤ React JS Tutorial :    • Reactjs   ➤ React Router Tutorial : https://www.youtube.com/watch?v=fDBD3E0zxTg ➤ Convert Html Template in Reactjs : https://www.youtube.com/watch?v=oQXsSpuXUl4 ➤ ASP.Net WEB API Tutorial : https://www.youtube.com/watch?v=ouiHedLJjTs ➤ SQL SERVER Tutorial : https://www.youtube.com/watch?v=cqgVxKdDq3Y ➤ HTML Crash Course: https://www.youtube.com/watch?v=65qD_SaiKWA ➤ Payment Gateway Integration : https://www.youtube.com/watch?v=CA2IR2AEN7I ➤ WEB API With SQL SERVER : https://www.youtube.com/watch?v=ifgZdY3T0Gs Subscribe to this channel ➤ https://bit.ly/2IaMZUr Must buy Programming Laptops : https://amzn.to/3AlLH03 https://amzn.to/3QQrgiz https://amzn.to/3RaqBIQ https://amzn.to/3R1EmJS https://amzn.to/3QHU9gZ https://amzn.to/3QNcAkk https://amzn.to/3QKtzno https://amzn.to/3dTMbmm https://amzn.to/3dQJ7aG Share, Support, Subscribe Now : Youtube 🎥 : null Instagram 📷 : https://instagram.com/openprogrammer Twitter 🐦 : https://twitter.com/openprogrammer Facebook 👍 : https://facebook.com/openprogrammer Website 🌐 : https://www.connectedprogrammer.com/ ⭐️Tags : ⭐️ #JWTToken #.netcoretoken #.netcorewebapitoken ⭐️ Your Queries : ⭐️ How to setup JWT authorization in asp.net core 6 with swagger in hindi || Jwt authorization with swagger in hindi || JWT atuhentication in hindi || JWT authentication in hindi with swagger || asp.net core 6 version jwt authorization token with swagger || JWT Authentication in asp.net core 6.0 with swagger Enable JWT authentication enable in swagger JSON Web Token Introduction || How does JWT authentication work? || What is JWT authentication in REST API? || Is JWT better than session? || Is JWT the same as OAuth? || JWT Authentication || JWT authentication: Best practices and when to use it || What Is JWT?
