Calculate AWS fingerprint from SSH private key
Note that fingerprint you can see on AWS Key pairs tab in AWS console is not the same as fingerprint that ssh-keygen gives.
If key was uploaded:
ssh-keygen -f <myprivatekey> -e -m PKCS8 | openssl pkey -pubin -outform DER |openssl md5 -c
If key was generated by AWS:
The AWS Auto Scaling Goup, configured with a customised Cloud-Init file, sends a notification to an SNS Topic, which in turn passes it onto an SQS queue that the Salt Master is subscribed to. A Reactor watches for the auto scaling events and pre-approves the new minion based on its Auto Scaling group name and instance ID.

| # OBJECTIVE: Install Arch Linux with encrypted root and swap filesystems and boot from UEFI. | |
| # Note: This method supports both dedicated Arch installs and those who wish to install Arch on a multi-OS-UEFI booting system. | |
| # External USB HDD/SSD Installers Notes: Encrypted Arch installs can be booted and run from an external USB HDD or SSD, but | |
| # only when the installation is correctly set up. There are several necessary changes to my standard procedure you'll want | |
| # to make during the install process. Read my External USB HDD/SSD Installation section below before proceeding. |
