What is WireGuard?

WireGuard is a modern, fast, and secure VPN (Virtual Private Network) protocol designed to be simpler and more performant than traditional VPN solutions like OpenVPN or IPsec. It uses state-of-the-art cryptography and runs as a kernel module, making it extremely lightweight with minimal attack surface. WireGuard creates encrypted tunnels between devices, allowing secure communication over untrusted networks like the internet.

How does WireGuard work?

WireGuard uses a cryptographic key exchange system based on public/private key pairs. Each device (server or client) has its own private key kept secret and a corresponding public key shared with peers. When two devices want to communicate, they exchange public keys and use them to establish an encrypted tunnel. The configuration is straightforward: define an interface with your private key and address, then add peers with their public keys and allowed IP ranges.

Tool description

This WireGuard Configuration Generator creates ready-to-use configuration files for both WireGuard servers and clients. Simply enter your network parameters, add clients, and the tool automatically generates properly formatted configuration files that can be directly deployed to your WireGuard installations.

Examples

Server Configuration Output:

# wg-server configuration
[Interface]
PrivateKey = ABC123...xyz=
Address = 10.0.0.1/24
ListenPort = 51820
SaveConfig = true

# client1
[Peer]
PublicKey = DEF456...abc=
AllowedIPs = 10.0.0.2/32

Client Configuration Output:

# client1 configuration
[Interface]
PrivateKey = GHI789...def=
Address = 10.0.0.2/32
DNS = 1.1.1.1, 1.0.0.1

[Peer]
PublicKey = JKL012...ghi=
Endpoint = your-server-ip.com:51820
AllowedIPs = 0.0.0.0/0, ::/0
PersistentKeepalive = 25
