Im currently working with encryption for both Python and Javascript. I have currently working with RSA combined with base64 where I have this code for both python and javascript:

Javascript:

const NodeRSA = require('node-rsa');

const key = new NodeRSA("-----BEGIN PUBLIC KEY-----MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQCzjsLuAJ18f71jg+ZG/wef3FuFTFK2ZvqBPjM7EwVj1FcLkzfixx6D6u59leFgW4SptOIgBtm9OGW1cCmxYLx1nHkugvoAL9g/vnIz6ejVTcoVYPJwkaGum3qXCPW6Km0canc7/DJtM//Zum40AZls/ZFjJ2YJrEOfevIU77urUwIDAQAB-----END PUBLIC KEY-----");

var x = {store_id: 1, url_key: 'hello_world.html', category_id: ''}

const data = key.encrypt(JSON.stringify(x), 'base64')
console.log(data)

and Python:

import base64
import json

import rsa

pub = rsa.PublicKey.load_pkcs1_openssl_pem('''-----BEGIN PUBLIC KEY-----\nMIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQCzjsLuAJ18f71jg+ZG/wef3FuFTFK2ZvqBPjM7EwVj1FcLkzfixx6D6u59leFgW4SptOIgBtm9OGW1cCmxYLx1nHkugvoAL9g/vnIz6ejVTcoVYPJwkaGum3qXCPW6Km0canc7/DJtM//Zum40AZls/ZFjJ2YJrEOfevIU77urUwIDAQAB\n-----END PUBLIC KEY-----''')
payload = json.dumps({'store_id': 1, 'url_key': 'hello_world.html', 'category_id': ''},
                     separators=(',', ':')).encode('utf-8')

bs64_encoded = base64.b64encode(rsa.encrypt(payload, pub))
print(bs64_encoded.decode('utf-8'))

Output for Javascript:

mBXCV95Dpc0sg8gigQWv1WdJNkLU9rlVQTcsFy6ell0PTsDfPh8EAVqFZBL6zM3i3S7P0Z2rSRCJQ6xGQag4yeupZ8yJIttyLk1HNIowhB/nPWqUxAPn59cL2uqP5hMBXSPLYet67DWEzwNkmHA4W2pZc/ysKrTLqUQBYGRYQQ97z3n8kGaGQLgg5afKXHPFne6qEjhiupH6cRKzwj7jwy0fEosBleyDaXWOaNtrK2drGpyR3OFVVq2QtlyXLt1kbYAV01eRSZatgRH0pNXQKEkwqSDmoEz4txDEaP/KU4nwroN/r40cOHYd1/pW2aMqjY0yTM3fm4rWM/nRQAYX5w==

Output for Python:

OPpU/VMEq7238VQamObgNX8r7pbUnvvNQ/5ie42EpWF3yXT4vNUFxNVaqvMdlNYft6FvVTs5xoAuuhg2JKRk6ar0EvIQL2ZxasIvAIpLhDazJijU5+JQ7u9nEY03QrXbrfHro3620g26LtOw5hAjjUy7pKLKO0hNO+bdobUZrio=

and as you can see there is a difference and the output of Javascript is the correct output that im looking for but not python (When using the output, it thorws an invalid data while Javascript response with 200 (correct data)).

My question is that why does it has any difference between Javascript and python when it comes to encryption and how can I make the output of Python to be correct?
