decode jwt token without using jwt.io

How to decode jwt token using postman in 2 minutes !!

3 parts of JWT token described by Millan Kaul

Background:

Most of the developers and QA have pasted jwt tokens on jwt.io as nothing else seems more reliable than that to copy your secrets.

But its less of a fact that we read this on the same website

Warning: JWTs are credentials, which can grant access to resources. Be careful where you paste them! We do not record tokens, all validation and debugging is done on the client side.

Postman Test tab

var jwt_token = 'eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiIxMjM0NTY3ODkwIiwibmFtZSI6IkpvaG4gRG9lIiwiaWF0IjoxNTE2MjM5MDIyfQ.SflKxwRJSMeKKF2QT4fwpMeJf36POk6yJV_adQssw5c'
var one = JSON.parse(atob(jwt_token.split('.')[0]));
var two = JSON.parse(atob(jwt_token.split('.')[1]));
var three = jwt_token.split('.')[2];
console.log (one);
console.log (two);
console.log (three);
var one1 = JSON.stringify(two)
pm.test('one -----> ' + JSON.stringify(one), function () {});
pm.test('two -----> ' + JSON.stringify(two), function () {});
pm.test('three ---> ' + three, function () {});
