JWT uses base64url encoding, not base64 encoding

Thanks. I'm happy to take a PR, but will otherwise add it directly. You also remind me that in the js code I based myself on there is some extra pre-processing, which I should look at

function urlBase64Decode(str) {
    var output = str.replace('-', '+').replace('_', '/');
    switch (output.length % 4) {
        case 0:
            break;
        case 2:
            output += '==';
            break;
        case 3:
            output += '=';
            break;
        default:
            throw 'Illegal base64url string!';
    }
    return window.atob(output);
}

Have pushed a new release with your function and some length handling per my answer

You're welcome - and you provided half the code!
Hope you will consider starring the library if you find it useful.
