No, the topic of this post is not referring on how to certify yourself after following a specific Pluralsight course.
I was looking for an easy way to create a self-signed certificate and Google brought me to the following blog post: https://www.pluralsight.com/blog/software-development/selfcert-create-a-self-signed-certificate-interactively-gui-or-programmatically-in-net. Keith Sparkjoy created a UI-based tool that uses a combination of the .NET Framework and the CryptoAPI to create self-signed X.509 certificates.
Although it is an old blogpost, the tool is still usefull today. Download the project here.
