WebSocketsSecure (WSS) Configuration

Prerequisites

• certbot and openssl
• RocketSockets v1.1 or above

Instructions

1. Run sudo certbot certonly on your server that is hooked up to a domain name to generate a HTTPS certificate. Use the standalone option.
2. cd into the directory specified by certbot in its final stages (etc/letsencrypt/someOtherPath) and run the following command: openssl pkcs12 -export -out certificate.pfx -inkey privkey.pem -in cert.pem. Configure the certificate with a password and remember it.
3. Copy the generated certificate.pfx to the folder where ./RocketSockets lives.
4. Configure RocketSocket’s appsettings.json file with the following settings:

{
  "RocketSocketsConfig": {
    // snip
    "useSecureWebSockets": true,
    "webSocketsCertificatePath": "certificate.pfx",
    "webSocketsCertificatePassword": "passwordYouSelected"
  }
}

You should be able to run WebSocketsSecure servers now! A secure server will start automatically, but you can start secure servers with the --secure switch and nonsecure servers with the --nosecure switch.
