JWT payload blank when decrypting in

I am trying to decrypt my access token’s payload from JWT to see the “sub” and “exp” values.

This is the token I get:

eyJhbGciOiJkaXIiLCJlbmMiOiJBMjU2R0NNIiwiaXNzIjoiaHR0cHM6Ly9ndXR0ZXItYXBwLnVzLmF1dGgwLmNvbS8ifQ. .4VZtZTJHtkCb-lOk.yYJ3H3RR4vrg3HbSkKuNiB0SivUGl5G07oH_DabsxiZ-MSe1BeKZ1ss0uZm8EnWRrANl_y8pVoueF3QYswGV6JcgyLFsuIquJGnPmEdV71BKumvMOSX4GsxD5vB6ilKojFhPyo6TWBLB7LLMhCCudmtuS3wgQmNdBlKnmtGn19oaMFjTMy9BNCIvUjOTnw-eQpU8tA3KPJAm99A3827sMBWQ4JsNwBS8TMttW8ZTw0X9-doBnegqM0-PUb4tuNo9waUfSyj-xrvfXjfh7cDQyc8_0lG0jxUaikBsagoj358zFjiqYQ4iQgPpZGUr.ZdXs2ZE76Gd2qkDZzXZzgA

This is the code i use to decrypt it:

function parseJwt(token) {
        var base64Url = token.split('.')[1];
        var base64 = base64Url.replace(/-/g, '+').replace(/_/g, '/');
        var jsonPayload = decodeURIComponent(atob(base64).split('').map(function(c) {
            return '%' + ('00' + c.charCodeAt(0).toString(16)).slice(-2);

        return (jsonPayload);

I’ve also tried using the JWT debugger at https://jwt.io/ but it also returns a blank payload.

Side note, I’m using the Cordova Quickstart SDK.

Any help would be greatly appreciated :slight_smile:

Hi @JustZakary,

Welcome to the Auth0 Community!

That looks like an encrypted token. Can you confirm you are sending a valid audience in order to return a non-encrypted JWT?
