A few forumers asked me questions regarding reading of MyKad surface information. The answer is there is no encryption; it is just about knowing what (APDU) command to send.

There will be 5 APDU commands that I'll introduce. I name them as:

Select Application
Get Response
Set Length
Select Info

MySQL

Getting started:

	#!/bin/bash

	AWS_DEFAULT_REGION="ap-northeast-1"
	AWS_ACCESS_KEY_ID="YOUR ACCESS KEY HERE"
	AWS_SECRET_ACCESS_KEY="YOUR SECRET ACCESS KEY HERE"

	INSTANCE_ID_URL="http://169.254.169.254/latest/meta-data/instance-id"
	INSTANCE_ID=$(curl -s ${INSTANCE_ID_URL})

	SERVER_STATUS_URL="http://localhost/php-fpm-status"

	#!/usr/bin/env bash
	#
	# Get the value of a tag for a running EC2 instance.
	#
	# This can be useful within bootstrapping scripts ("user-data").
	#
	# Note the EC3 instance needs to have an IAM role that lets it read tags. The policy
	# JSON for this looks like:
	#
	# {

	name: "GoogleNet"

	input: "data"
	input_dim: 10
	input_dim: 3
	input_dim: 224
	input_dim: 224

	# hierarchy 1
	# conv -> relu -> pool -> lrn

	server {
	listen 80;
	server_name example.com www.example.com;

	if ($http_x_forwarded_proto = "http") {
	return 301 https://$server_name$request_uri;
	}

	... directives to generate a response
	}
