Mini tutorial for configuring client-side SSL certificates.

Client-side SSL

For excessively paranoid client authentication.

Using self-signed certificate.

Create a Certificate Authority root (which represents this server)

Organization & Common Name: Some human identifier for this server CA.

openssl genrsa -des3 -out ca.key 4096
openssl req -new -x509 -days 365 -key ca.key -out ca.crt

tag function for formatting console.log(..) statements
function logger(strings,...values) {
var str = "";
for (let i = 0; i < strings.length; i++) {
if (i > 0) {
if (values[i-1] && typeof values[i-1] == "object") {
if (values[i-1] instanceof Error) {
if (values[i-1].stack) {
str += values[i-1].stack;
continue;
}

Strings

String.prototype.*

None of the string methods modify this – they always return fresh strings.

  • charAt(pos: number): string ES1

    Returns the character at index pos, as a string (JavaScript does not have a datatype for characters). str[i] is equivalent to str.charAt(i) and more concise (caveat: may not work on old engines).

Full socket.io client and server example

Last updated: 2021-02-21, tested with socket.io v3.1.1

This is the simplest implementation you will find for a client/server WebSockets architecture using socket.io.

To see a full explanation, read my answer on SO here: https://stackoverflow.com/a/24232050/778272.
