How to generate & use private keys using the OpenSSL command line tool

How to Generate & Use Private Keys using OpenSSL's Command Line Tool

These commands generate and use private keys in unencrypted binary (not Base64 “PEM”) PKCS#8 format. The PKCS#8 format is used here because it is the most interoperable format when dealing with software that isn't based on OpenSSL.

OpenSSL has a variety of commands that can be used to operate on private key files, some of which are specific to RSA (e.g. openssl rsa and openssl genrsa) or which have other limitations. Here we always use

LastPass Pwned Passwords checker

LastPass Pwned Passwords checker

This is a script for checking if any of the passwords you have stored in LastPass have been exposed through previous data breaches.

To use the script you need to have Python 3 installed and you need a CSV export of your LastPass vault. The export can be generated from the LastPass CLI with:

lpass export > lastpass.csv

or can be extracted with the browser plugin by going to the LastPass icon → More Options → Advanced → Export → LastPass CSV File (note that I did have problems getting this to work).

Let's encrypt wildcard TLS certificates for Azure DNS using cert-manager on AKS (Azure Kubernetes Service)

This gist will guide you through the setup of a wildcard Let's encrypt TLS certificate.

Let's encrypt

Let’s encrypt is one of a new kind of Certificate Authority. You can get a TLS certificate from them for your website free of charge and without any manual overhead. These certificates are trusted in most browsers that are out there and will show up as valid. Instead of sending Mails or even paper around you can call an API and prove your domain ownership with simple challenges. Basically you call the API with a hostname or domain name you need a TLS certificate for and you get back a challenge string that you need to put in a well known location on your http host or as a txt record in your dns system.

The little helper for Kubernetes: Cert-Manager

You can find many clients that manage the proces

Shebang Scripts in Nix Derivations #nix

Shebang Scripts in Nix Derivations

When you create a derivation, and you later run nix-build on the Nix derivation. Nix will transport the source to a chrooted temporary build directory (this actually can be configured in NixOS configuration.nix). The reason to do this is to ensure deterministic builds in a clean environment.

However the environment is so clean that no dependencies that you don't explicitly declare will be available in that environment. Also things that you take for granted like PATH is something that needs to be explicitly built.
