var ncrypter = require('ncrypter');
//use encode on your frontend with number of second you want it to change and the secret key
var encodedString = ncrypter.encrypt(2, 'mysecret1')
//use decode on your backend with same number of second and the same secret
var decodedString = ncrypter.decrypt(encodedString, 2, 'mysecret1');
console.log('permission granted -->', decodedString);
