Step 2: Install Required Packages

Before you begin the installation of Easy-RSA, you need to make sure that your system has some of the required packages. Open the terminal and run the following command:

sudo swupd bundle-add devpkg-openssl devpkg-pkgconfig devpkg-gcc

Step 3: Clone Easy-RSA

You can clone Easy-RSA using the following command:

Step 4: Install Easy-RSA

Once you have cloned the repository, move into the easy-rsa directory and run the installation script:

cd easy-rsa

This command will initialize the Public Key Infrastructure (PKI) in a directory named pki.

Step 5: Create CA Certificate and Key Pair

To create a Certificate Authority (CA) certificate and key pair in the PKI, run the following command:

./easyrsa build-ca

Step 6: Generating Server and Client Certificates

You can generate server and client certificates using the following command:

./easyrsa build-server-full server nopass
./easyrsa build-client-full client1 nopass

In the above commands, server and client1 are the names chosen for the server and client certificates, respectively.

Step 7 : Move the Certificates

Once the certificates have been generated, you need to move them along with other files to your OpenVPN server directory which includes the following files:

ca.crt
<client-name>.crt
<client-name>.key
ta.key

Step 8: Secure the Certificates

Now you need to secure the generated certificates by setting the proper file permissions to them. Run the following command to set the permissions:

chmod -R 700 /path/to/your/certificates
