Overview

I wrote about how to create a fullchain ssl certificate manually in a previous post. Today, I will show you how you can create fullchain ssl cert with only 3 commands.

We will use a tool named crtforge which is free and open-source application that you can find on Github.

Install crtforge

To install crtforge, you need Linux or macOS. You can also use the crtforge on Windows with wsl.

Terminal window
sudo curl -L -o /usr/bin/crtforge https://github.com/burakberkkeskin/crtForge/releases/latest/download/crtforge-$(uname -s)-$(uname -m) && \
sudo chmod +x /usr/bin/crtforge

These two command will install crtforge binary to your system.

Create a fullchain cert.

You can directly run crtforge with a appname and domains that app needs.

Terminal window
crtforge websiteApp myapp.com app.myapp.com

Congratulations 🎉, you will have your fullchain with 3 commands in total.

You can get the certs from the $HOME/.config/crtforge/default/websiteApp directory.

For detailed usage like custom root CA, custom intermediate CA and trusting the root CAs, you can check the readme of the repository.
