GPG + Git SSH Authentication and Signing on Windows 10

GPG + Git SSH Authentication and Signing on Windows 10

Introduction

This simple Gist will explain how to settup your GPG key to work for SSH authentication (with Git) and Git commit signing on Windows 10. This may seem straightforward on Linux, but there are certain tweaks needed on Windows.

No Cygwin, no MinGW, no Git Bash or any other Linux emulated environment. This works in pure Windows 10.

A guide for configuring Vault's SSH-CA

SSH CA use-case with Vault

In this scenario we are going to set up Vault to sign SSH keys using an internal CA. We will configure the SSH secrets engine and create a CA within Vault. We will then configure an SSH server to trust the CA key we just created. Finally we will attempt to SSH using a private key, and a public key signed by Vault SSH CA.

Prerequisites

  • This guide assumes you have already provisioned a Vault server, SSH host using OpenSSH server, and a SSH client machine.
  • The client system must be able to reach the Vault server and the OpenSSH server.
  • We will refer to these systems respectively as:
  • VAULT_SERVER

[How To] Synchronize NTP server to a GPS/PPS source

So, I want to have a GPS Receiver driving a PPS (pulse-per-second) signal to the NTP server for a highly accurate time reference service.

Introduction

There are at least a couple of ways to propagate the PPS signal to the ntpd (NTP daemon) service, plus some variants in each case. However, the GPS device must be seen as a device that sources two different types of data:

  • the absolute date and time, and
  • the 1Hz clock signal (PPS).

The first one provides the complete information (incl. date and time) about when now is, but with poor accuracy because data is sent over the serial port and then encoded using a specific protocol such as NMEA (National Marine Electronics Association). PPS provides instead a very accurate clock but without any reference to absolute time.
