Enabling HTTPS (TLS SSL) connection for AionWeb3 JSONRPC calls - aionnetwork/aion GitHub Wiki

INTRODUCTION

Securing traffic between client application and Kernel is common security case. AION provides conventional mechanism to enable HTTPS connection for JSON calls. Please refer to steps below.

Requirements

NGINX
AION Kernel
AION_Web3 API

Deployment

sudo apt-get update
sudo apt-get install nginx
ngnix -v
cd /etc/nginx
sudo openssl req -x509 -nodes -days 3650 -newkey rsa:2048 -keyout /etc/nginx/aion8545.key -out /etc/nginx/aion8545.crt

Configuration

sudo cp /etc/nginx/sites-enabled/default /etc/nginx/sites-enabled/default.orig.<YYYYMMDD>
sudo vim /etc/nginx/sites-enabled/default

Replace the file code with following code

server {

    listen 443;
    server_name localhost;
    ssl_certificate           /etc/nginx/aion8545.crt;
    ssl_certificate_key       /etc/nginx/aion8545.key;

    ssl on;
    ssl_session_cache  builtin:1000  shared:SSL:10m;
    ssl_protocols  TLSv1 TLSv1.1 TLSv1.2;
    ssl_ciphers HIGH:!aNULL:!eNULL:!EXPORT:!CAMELLIA:!DES:!MD5:!PSK:!RC4;
    ssl_prefer_server_ciphers on;

    access_log            /var/log/nginx/aion8545.access.log;

    location / {
      proxy_set_header        Host $host;
      proxy_set_header        X-Real-IP $remote_addr;
      proxy_set_header        X-Forwarded-For $proxy_add_x_forwarded_for;
      proxy_set_header        X-Forwarded-Proto $scheme;

      proxy_pass          http://localhost:8545;
      proxy_read_timeout  90;

      proxy_redirect      http://localhost:8545 https://localhost;
    }
  }

Restart NGINX

sudo systemctl restart nginx && sudo systemctl status nginx

Client configuration

Create aionweb3test.js with the code below

process.env.NODE_TLS_REJECT_UNAUTHORIZED = "0";
var Web3 = require('web3')
var web3 = new Web3(new Web3.providers.HttpProvider("https://localhost"));
console.log(Web3)

Testing

Execute nodejs script as follow

node aionweb3test.js

SUMMARY

By completing the steps the HTTPS encrypted connection is enabled with end-to-end secure traffic.
