Create Root CA (Done once)

Create Root Key

Attention: this is the key used to sign the certificate requests, anyone holding this can sign certificates on your behalf. So keep it in a safe place!

openssl genrsa -des3 -out rootCA.key 4096

These are my own personal notes on how i setup a Pi Zero W as an access points it is a blatant copy of this: https://gist.github.com/tcg/0c1d32770fcf6a0acf448b7358c5d059 but is just missing a couple of things from: http://imti.co/post/145442415333/raspberry-pi-3-wifi-station-ap and like tcg, this is not intended as a guide but notes as i will invariably have to rebuild this sometime and i have broken biscuits for brains.

1. making the pi zero accesible from a computer

this is really just the same info as here https://gist.github.com/gbaman/975e2db164b3ca2b51ae11e45e8fd40a

• flash raspbian lite to sd card
• unplug and replug sd card adapter if necessary to see 'boot' drive
• edit cmdline.txt add: modules-load=dwc2,g_ether after the word rootwait
• edit config.txt and add dtoverlay=dwc2 to the end of the file
• create a blank file called ssh
