SSH Certificate based Authentication - Quick Guide

Certificate Authority (CA) Server	Host Server(s)	Client(s)
	Host Server Certificate Configuration
This is the server typically managed by a security team. The root CA private keys are held on this server and should be protected. If these keys are compromised it will be necessary to Revoke & Rotate/Recreate ALL Certificates!!	These are the servers that are being built or reprovisioned. The Host CA Signed Certificate is used to prove Host Authenticity to clients. It is sent to the ssh client during the initial handshake when a ssh client attempts to login.	The user laptop or server that's runing the ssh client. The Client CA Signed Certificate is used to prove Client Authenticity to the Host Server
Step 1. Create HOST CA signing keys : Example ssh-keygen -t rsa -N '' -C HOST-CA -b 4096 -f host-ca	Step 2. Let's generate a fresh set of ssh RSA HOST keys with 4096 bits. Typically the keys are generated by default

Laravel's Dependency Injection Container in Depth

Translations: Korean (by Yongwoo Lee)

Laravel has a powerful Inversion of Control (IoC) / Dependency Injection (DI) Container. Unfortunately the official documentation doesn't cover all of the available functionality, so I decided to experiment with it and document it for myself. The following is based on Laravel 5.4.26 - other versions may vary.

Introduction to Dependency Injection

I won't attempt to explain the principles behind DI / IoC here - if you're not familiar with them you might want to read What is Dependency Injection? by Fabien Potencier (creator of the Symfony framework).

	return $args;
