Easy-rsa is a package used to manage certificates for OpenVPN. The package is available on GitHub and can be easily installed on macOS using the following steps:
Homebrew is a package manager for macOS that makes it easy to install command-line tools and other software.
To install Homebrew, open the Terminal application and run the following command:
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
To install easy-rsa, open the Terminal application and run the following command:
brew install easy-rsa
This will download and install easy-rsa on your macOS system.
To verify that easy-rsa has been installed correctly, run the following command in the Terminal application:
easyrsa
If the installation is successful, you should see a list of available commands.
Before you can use easy-rsa, you'll need to configure it. To do this, navigate to the easy-rsa directory using the following command:
cd /usr/local/opt/easy-rsa
Next, copy the example configuration file to a new file named vars:
cp vars.example vars
Finally, open the vars file in your favorite text editor and make any necessary changes. This includes setting the default values for the various options, such as the location of the CA certificate and key, the name of the directory where certificates will be stored, and so on.
Now that you've installed easy-rsa and configured it, you can start generating certificates for OpenVPN. Congratulations!
