Rebooting...

Thanks a lot if this can work since this will be an important part of my project since I don't want anyone to send a json file to my server and crash it.. My bet is if my nodejs server have to decrypt it will help with security. I'm using crypto-js on my server. I will make a post with my crypted data and decrypt on nodejs server. I like simple code, and I may be dumb but in the beginning I just wanted to use aes key. I don't really understand what the iv is? Another password for more security?

Also I know this is a stupid question(yep I'm a real noob) but can this run 24/24 for 10 years or there is a chance that there is a leak somewhere and it will end up crashing? Silly question I know(or guess)

Also how do I receive a crypted json on server side and decrypt it?

I have so much gratitude if you answer, thank you for reading me

To prove my incompetence and show you how much nursing I need, that's how I encrypt and decrypt everything on my server:

const cryptojs = require('crypto-js');
password = 'd6F3Efeq3000sjdsjASSSS';

function encrypt(text){
  const result = cryptojs.AES.encrypt(text, password);
  return result.toString();
}

function decrypt(text){
  const result = cryptojs.AES.decrypt(text, password);
  return result.toString(cryptojs.enc.Utf8);
}

I started programming with node 2 weeks ago. And my programming skills are really really basic level of c++ without any knowlege of object because I took that programming tutorial way too long ago and and I don't remember

Did you try the example in nodejs folder? How did this end up? Can we close the issue that is linked to old version?
