How to setup your own CA with OpenSSL

For educational reasons I've decided to create my own CA. Here is what I learned.

First things first

Lets get some context first.

#!/bin/bash

# Settings: edit these as needed
PROJECT_NAME="test"
OUTPUT_DIRECTORY="~/Documents/MapBox/export/"

# first change into TileMill code directory
cd /Applications/TileMill.app/Contents/Resources/

# hint: use http://bboxfinder.com/ to get bounds in lon/lat

sudo xcodebuild -license
xcode-select --install # There will be a GUI prompt
sudo cpan SVN::Core # use the "sudo" method when prompted
# Then add this to your ~/.profile:
# export PATH=/Library/Developer/CommandLineTools/usr/bin:$PATH
# Then probably:
brew reinstall git
brew reinstall subversion

There are a bunch of reasons why this is convoluted, mostly in building the URL to make the request:

1. You have to rely on an AJAX request, this example uses jQuery
2. To make a GetFeatureInfo request, you must provide a BBOX for a image, and the pixel coordinates for the part of the image that you want info from. A couple of squirrely lines of Leaflet code can give you that.
3. Output formats. The info_format parameter in the request. We don't know a priori which will be supported by a WMS that we might make a request to. See Geoserver's docs for what formats are available from Geoserver. That won't be the same from WMS to WMS, however.
4. WMS services return XML docs when there's a mistake in the request or in processing. This sends an HTTP 200, which jQuery doesn't think is an error.
