  How to selectively remove items from an Azure blob storage container?

  In this article, I'll share a simple script for a simple use case: removing blobs from a virtual directory structure in a container in an Azure blob storage account. This should be useful for a case like ours; removing certain directories and subdirectories but not the whole container. But let's not get ahead of ourselves! What was the problem we had?

  How to update application settings for (all of your) App Services and Azure Functions on Azure using az cli?

  Anyone still remember Log4Shell? The incredibly easy-to-exploit, zero-day vulnerability in Log4j, a popular Java logging framework, that made arbitrary code execution extremely simple and straightforward. The vulnerability had existed unnoticed since 2013 and was simply a side effect of a nifty new feature implemented way back when. But that's enough of that. How serious was it? Well - Apache gave Log4Shell a CVSS severity rating of 10, the highest available score .

  How to export an App Service Certificate from Azure?

  Azure offers this great offering that is in my mind underutilized still - managed certificates that they'll renew for you. While the offering is called Azure App Service Certificates , they are not only limited to being used in App Services. Their biggest strengths lie in their ease of use, automation, and integration with different Azure services. These certs are automatically renewed, eliminating the need for manual certificate management.

  How to export a certificate and a private key from a .pfx using OpenSSL?

  Alright, so let's make this a quick one. I've had to google this multiple times, since I have to do this a couple of times per year, which is NOT often enough for me to remember it by heart, or even for my Terminal to remember the commands properly. So, long story short - here's how to export a PEM-formatted .cer -file and your private key (and optionally decrypt it as well!) from a .pfx -file containing both!
