How to install easy-rsa on OpenSUSE Latest

Easy-rsa is a tool that allows users to manage certificate authorities (CA), which are used to create and manage digital certificates for secure communication. In this tutorial, we will guide you on how to install it on OpenSUSE Latest in a step-by-step manner.

  1. First, open a terminal on OpenSUSE Latest by pressing Ctrl+Alt+T.

  2. Install the git package using the following command:

sudo zypper install git
  1. Clone the Easy-RSA repository from Github using the following command:
git clone https://github.com/OpenVPN/easy-rsa.git
  1. Change to the directory where you cloned the repository using the following command:
cd easy-rsa/easyrsa3
  1. Install easy-rsa by running the easyrsa script with the init-pki option:
./easyrsa init-pki
  1. Now generate the CA by running the following command:
./easyrsa build-ca
  1. After generating the CA, you can generate client and server certificates by running the following commands:
./easyrsa build-server-full server
./easyrsa build-client-full client

Note: Replace server and client with the names you want to give to your respective certificates.

  1. Now you need to copy the necessary files that have been generated into your server installation. You can use the following commands to copy the files:
sudo mkdir /etc/openvpn/keys/
sudo cp -v pki/ca.crt /etc/openvpn/keys/
sudo cp -v pki/private/server.key /etc/openvpn/keys/
sudo cp -v pki/issued/server.crt /etc/openvpn/keys/
sudo cp -v pki/issued/client.crt /etc/openvpn/keys/
sudo cp -v pki/private/client.key /etc/openvpn/keys/
  1. Now that you have all the files copied to your server, you can configure your OpenVPN connection to use these certificates. You can refer to OpenVPN documentation on how to do that.

Congratulations! You have successfully installed Easy-RSA on OpenSUSE Latest and generated a CA and client/server certificates.
