openssl rsa -in private.pem -pubout > public.pem
const jwt2 = require('jsonwebtoken');
const fs = require("fs")
const public_key = fs.readFileSync('public.pem');
const private_key = fs.readFileSync('private.pem');
var token=jwt2.sign({"user":"me"},private_key, { algorithm: 'RS256'})
var res = jwt2.verify(token, public_key, { algorithm: 'RS256'})
