![]() Open up a new folder in VS Code and enter the following to initialize the Golang Project Dependencies. Helps save a lot of time, rather than switching over to postman or other REST Clients. Another really cool reason to use VSCode for API development is the ability to send requests to the API right from the VS Code interface using the REST API conventions. The latest available version while writing this article is Go 1.18.1.Īlso, ensure that you have installed the Golang Extension on VS Code which helps a ton in improving the Golang development experience. Make sure you have the latest stable SDK of Golang. Visual Code will be the IDE of choice for the article (and probably every other Golang Article that I will be posting in the future), because of its ease of use and productivity. Let’s get started with implementing JWT Authentication in Golang REST API. Getting Started with JWT Authentication in Golang The third part of the token, which is the Signature, is used to verify that the JWT has not been tampered with. Note that sensitive data such as passwords should be never sent in through a JSON Web Token. It’s usually claims sent by the server like username, email, and stuff. The payload contains the data to be exchanged. The header contains the signing algorithm used such as RSA or HMAC SHA256. You can see that these tokens are separated into 3 parts with a period. Head over to jwt.io where there is a sample JWT for our understanding. ![]() Let’s see the structure of an actual JWT in action. ![]() JWT is a really good contender for securing REST APIs. JSON Web Tokens are an open, industry-standard RFC 7519 method for representing claims securely between two parties. ![]()
