How to install Easy-RSA on Linux Mint Latest

Easy-RSA is a command-line utility for managing a Public Key Infrastructure (PKI) for OpenVPN. It is designed to be simple, flexible and lightweight.

In this tutorial, we will guide you through the process of installing Easy-RSA on Linux Mint Latest. This guide assumes you have a basic knowledge of Linux command-line and have the necessary privileges to install software.

Prerequisites

Before we start, make sure that you have the following:

A Linux Mint Latest installation
A terminal or command-line interface

Steps to follow

First, you need to install the dependencies for Easy-RSA. Open your terminal and enter the following command:
```
sudo apt update
sudo apt install git libssl-dev liblzo2-dev libpam0g-dev
```
This will update your package list and install the necessary packages.
Next, you need to clone the Easy-RSA repository from GitHub. Enter the following command to clone the repository:
```
git clone https://github.com/OpenVPN/easy-rsa.git
```
This will create a new folder called easy-rsa in your current directory.
Navigate to the Easy-RSA directory by entering the following command:
```
cd easy-rsa/easyrsa3
```
This will take you to the Easy-RSA directory.
Now, you can generate a new PKI by typing the following command:
```
./easyrsa init-pki
```
This will initialize a new Public Key Infrastructure.
Next, you need to create a Certificate Authority (CA) by entering the following command:
```
./easyrsa build-ca
```
This will prompt you to enter a passphrase for the CA, and ask for other details such as the CA name and email address.
Finally, you can create a new server certificate by entering the following command:
```
./easyrsa build-server-full servername
```
Replace servername with the name you want to give to your server certificate. This will prompt you to enter a passphrase and other details such as the server name and email address.

Once the certificate is created, you can find it in pki/issued.

Congratulations, you have successfully installed Easy-RSA on Linux Mint Latest and created a new PKI with a CA and server certificate. You can now use these certificates with OpenVPN or any other application that requires SSL/TLS certificates.
