How Does OpenVPN Work?

OpenVPN Keygen establishes VPN tunnels by leveraging two primary protocols – Transport Layer Security (TLS) and Secure Sockets Layer (SSL). Both use certificates and encryption algorithms to encapsulate and secure traffic between the VPN server and clients.

The high level process includes:

1. Initialize connection between client and server
2. Authenticate and verify certificates to validate identities
3. Negotiate encryption algorithm (AES, Blowfish etc.)
4. Establish encrypted VPN tunnel
5. Securely pass traffic through the VPN tunnel
6. Terminate tunnel connection

Including certificates as part of establishing connections uses a Public Key Infrastructure (PKI) that ensures only authorized clients can connect. The TLS handshake authenticates the client to the server and negotiates the encryption algorithm providing data security.

Once established, the encrypted tunnel allows remote client devices to securely access resources on the private network as if locally connected. OpenVPN inspects and directs traffic through the tunnel including handling encryption/decryption and routing.

How to Set Up OpenVPN Keygen

Now that we’ve covered OpenVPN’s capabilities, advantages and use cases, let’s explore how to actually set up OpenVPN starting with the prerequisites:

Server Prerequisites

• Ubuntu or RHEL Linux instance
• Public IP address
• Forward appropriate ports (TCP 1194, UDP 1194)
• Enable IP forwarding on server

Client Prerequisites

• Windows, Linux, MacOS or mobile device
• Admin/root access to install software
• Certificate file from server

With the prerequisites in place, the general setup process includes:

1. Install OpenVPN server – Use apt-get install openvpn or yum install openvpn on Linux distro. Also install EasyRSA for certificate authority (CA).

2. Generate CA and certificates – Utilize EasyRSA to generate root CA certificate and keys along with individual certs to distribute to each client.

3. Configure VPN server – Modify /etc/openvpn/server.conf file to specify TCP vs UDP, encryption cipher, authentication options, networking setup and other parameters.

4. Install client – Download and install OpenVPN client software onto Windows PCs, Mac laptops, smartphones or routers.

5. Import certificate to client – Add user certificate to new connection profile along with VPN server’s hostname/IP and configured port.
