Protocol comparison

Feature WireGuard OpenVPN
Speed Faster Slower
Security Modern (Curve25519) Very secure (OpenSSL)
Complexity Simple (~4000 lines) Complex (~100k lines)
Certificates Not required Requires PKI

Note: Choose WireGuard for simplicity and performance. OpenVPN is better if you need maximum compatibility or legacy device support.

Frequently Asked Questions

What is the difference between OpenVPN and WireGuard?

WireGuard is more modern and faster: it uses Curve25519, has only ~4000 lines of code, requires no PKI certificates, and runs directly in the Linux kernel. OpenVPN is more mature and compatible: it is based on OpenSSL, supports more legacy devices, and allows user+password authentication in addition to certificates. WireGuard is ideal for performance and simplicity; OpenVPN for maximum compatibility.

How do I configure a VPN with the generated files?

For OpenVPN, save the .ovpn file and run: openvpn config.ovpn. For WireGuard, save wg0.conf to /etc/wireguard/ and run: wg-quick up wg0. In both cases you need the corresponding client installed. The tool generates production-ready configurations — you only need to adjust your server IP addresses.

Which protocol should I choose for my VPN?

Choose WireGuard if you prioritize speed, low latency, and simple setup, especially for mobile connections or resource-constrained servers. Choose OpenVPN if you need legacy device support, multi-factor authentication, or if your firewall blocks UDP (WireGuard uses UDP only, OpenVPN supports TCP as well).

What are .ovpn and wg0.conf files?

.ovpn is the OpenVPN configuration format: it bundles certificates, keys, server address, and tunneling options into a single file. wg0.conf is the WireGuard format: it defines the local interface (Address, PrivateKey) and remote peers (PublicKey, Endpoint, AllowedIPs). Both are plain-text configuration files placed in the VPN client configuration directory.
