JSON Web Token Decoder In jQuery

A jQuery-based JWT decoder that provides a user-friendly interface to decode and analyze JSON Web Tokens on the web.

Just paste the JSON Web Token string in the input, and the JWT decoder will decode the payload and signature for you to view. This allows you to quickly see the claims and verify the signature of a JWT for debugging or authentication purposes.

What Are JSON Web Tokens:

JSON Web Tokens (JWTs) are an open, industry-standard method (RFC 7519) for securely transmitting information between two parties. JWTs are compact, URL-safe, and self-contained, meaning they can be easily transmitted via URL, POST parameter, or inside an HTTP header. They also contain all the required information about the user, eliminating the need to query a database more than once. JWTs are widely used for authentication and authorization purposes in modern web applications.

How to use it:

1. Create the HTML for the JWT Decoder.

<label for="token">Encoded Token</label>
<input type="text" id="token">

<label for="decoded">Payload</label>
<textarea id="decoded"></textarea>

<label for="analyzed">Interesting Values</label>
<pre id="out"></pre>

<button type="submit" id="decode">Decode</button>

2. Load the main script index.js after jQuery library. That's it.

<script src="/path/to/cdn/jquery.slim.min.js"></script>
<script src="/path/to/index.js"></script>
