create-dotnet-devcert

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

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.

dotnet-sdk (Version >= 5.0)
libnss3-tools
- ubuntu: sudo apt install libnss3-tools
- arch: sudo pacman -S nss
- fedora: sudo dnf install openssl nss-tools

Simply run the script needed for your distribution.

Ubuntu based distributions: ./scripts/ubuntu-create-dotnet-devcert

Arch based distributions: ./scripts/arch-create-dotnet-devcert

Fedora based distributions: ./scripts/fedora-create-dotnet-devcert

Use the -s to also save the certificate into the home folder so it can be manually imported into other programs.
