Currently, there is an explosion of tools that aim to manage secrets for automated, cloud native infrastructure management. Daniel Somerfield did some work classifying the various approaches, but (as far as I know) no one has made a recent effort to summarize the various tools.

This is an attempt to give a quick overview of what can be found out there. The list is alphabetical. There will be tools that are missing, and some of the facts might be wrong--I welcome your corrections. For the purpose, I can be reached via @maxvt on Twitter, or just leave me a comment here.

There is a companion feature matrix of various tools. Comments are welcome in the same manner.

Setup with TinyCore Linux (RAM only OS) on Raspberry Pi Zero W on Windows

These are the steps taken to setup piCore 14 on a Raspberry Pi with only Wi-Fi (no ethernet)
Newer version might work as well (or maybe even better), but have not been tested.

Set up piCore

Download the piCore image
Unpack the .zip file and write the .img file to the SD-Card (using Raspberry Pi Imager for example)
Move the SD-Card to the Pi, plug in a keyboard and a screen, plug in the power source
Execute backup shell command after the first boot to save generated unique SSH keys which will be used during next boots.

	P-code for PL/0 machine

	[ref] https://en.wikipedia.org/wiki/P-code_machine
	[ref] http://blackmesatech.com/2011/12/pl0/pl0.xhtml

	The PL/0 virtual machine was originally specified by Nicklaus Wirth in his book
	Algorithms + Data Structures = Programs; it's used as the target machine for a
	PL/0 compiler.
