create-dotnet-devcert

A simple script that creates and trusts a self-signed development certificate for dotnet on Ubuntu.

What does the script do

The script uses openssl to create a self-signed certificate. The certificate will then be imported and trusted at

• System certificates - to enable service-to-service communication
• User nssdb - to trust the certificate in supported application like Chromium or Microsoft Edge
• Snap Chromium nssdb - to trust the certificate in Chromium if installed via snap
• Snap Postman nssdb - to trust the certificate in Postman if installed via snap

In addition the certificate will be imported into dotnet so that it will be used as a development certificate in ASP.NET Core.

Prerequisites

• dotnet
• libnss3-tools (install via sudo apt install libnss3-tools)

Usage

Simply run the script.
